Creator An entity primarily responsible for making the resource Husin, Husni Date A point or period of time associated with an event in the lifecycle of the resource 2011-12-01 Description An account of the resource Crystalline sodium tantalate doped with La3+ ions (La/NaTaO3) has been successfully synthesized by sol-gel technique. The photocatalysts have been prepared by mixing of TaCl5, NaOH, and La(NO3)3.2H2O in the aqueous solution of H2O2. The resulting materials are characterized by X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), and transmission electron microscopy (TEM) to provide useful information about crystallinity and morphology. All samples are exactly indexed as the pure NaTaO3 orthorhombic structure with the space group Pcmn. The XRD spectra displayed a single-phase NaTaO3 structure without any impurity phase, suggesting that lanthanum is uniformly incorporated into the NaTaO3 lattice. TEM images indicates that the particle sizes of the La-doped NaTaO3 powders are approximately 30-80 nm, while the particle sizes of the non-doped NaTaO3 are around 80-250 nm. Doping lanthanum in the NaTaO3 is able to prevent agglomeration, result in particle size, and better crystallinity. The La/NaTaO3 crystal structures reveal that a certain amount of lattice distortion due to the La3+ ions occupying the Na+ sites results in the increase of crystallite size. Powder formation mechanisms for both non-doped NaTaO3 and La-doped NaTaO3 are proposed based on the experimental results.Keywords: La-doped sodium tantalum oxide, photocatalyst, sol-gel, perovskite, orthorhombic Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context http://jurnal.unsyiah.ac.id/RKL/article/view/742 Language A language of the resource eng Publisher An entity responsible for making the resource available Chemical Engineering Department, Syiah Kuala University, Banda Aceh, Indonesia Relation A related resource http://jurnal.unsyiah.ac.id/RKL/article/view/742/696 Source A related resource from which the described resource is derived Jurnal Rekayasa Kimia & Lingkungan; Vol 8, No 2 (2011): Jurnal Rekayasa Kimia & Lingkungan; 60-65 2356-1661 1412-5064 Title A name given to the resource Preparasi dan karakterisasi fotokatalis NaTaO3 didoping ion lantanum (La/NaTaO3) dengan metode sol-gel Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Contributor An entity responsible for making contributions to the resource Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

The aim of this work is to study the photocatalytic properties of NaTaO3 and NiO incorporated NaTaO3 used in water splitting reaction. The NaTaO3 powder with high crystallinity has been synthesized by a H2O2-asissted sol-gel route calcined at a temperature of 900 oC. NiO as a cocatalyst is deposited by impregnation of Ni(NO3)2.6H2O solution. The catalysts are characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), high resolution transmission electron microscopy (HRTEM), and diffuse reflectance UV-Vis (DR-UV-Vis). The photocatalysts have a band gap energy ca. 4.01 and 4.00 eV (corresponding to absorption edge of 310 and 311 nm). Photocatalytic activity towards hydrogen generation from water is investigated using a glass reactor under ultra violet (UV) light illumination. Photocatalytic of H2 and O2 production on the pristine NaTaO3 are 0.61 and 0.30 mmol g-1 cat.h-1, respectively. The activities are greatly enhanced 8.5 times higher by the incorporation of NiO as cocatalysts on the prepared oxides. NiO is found to give rise to more efficient photocatalytic activity for hydrogen evolution. The NaTaO3 nanoparticles produces using this facile have: better crystallinity, smaller size, and higher photocatalytic activity.Keywords: Sodium tantalum oxide; Nickel oxide; Sol-gel; impregnation; Hydrogen evolution Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context http://jurnal.unsyiah.ac.id/RKL/article/view/254 Language A language of the resource eng Publisher An entity responsible for making the resource available Chemical Engineering Department, Syiah Kuala University, Banda Aceh, Indonesia Relation A related resource http://jurnal.unsyiah.ac.id/RKL/article/view/254/240 Source A related resource from which the described resource is derived Jurnal Rekayasa Kimia & Lingkungan; Vol 9, No 2 (2012): Jurnal Rekayasa Kimia & Lingkungan; 51-56 2356-1661 1412-5064 Title A name given to the resource Produksi Hidrogen Secara Fotokalitik dari Air Murni Pada Katalis NaTaO3 Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Contributor An entity responsible for making contributions to the resource Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

The aim of this work is to study the catalytic properties of copper based catalysts used in the steam reforming of methanol. This method is known as one of the most favorable catalytic processes for producing hydrogen on-board. The catalyst was prepared by impregnation method with Cu loading of 5%, 10%, and 15%,. The X-ray diffraction pattern shows that the catalyst compositions are Cu, CuO, ZnO, and Al2O3. The reactions were carried out in the fixed bed tubular reactor operating at temperatures of 150oC, 200oC, 250oC, 300oC, and 350oC and atmospheric pressure. The product was analyzed using Shimadzu Gas Chromatography GC 8A with mole sieve 5A and porapak-N column 80/100 mesh. The performance of the catalyst shows that the highest methanol conversion was 86% over Cu/ZnO/Al2O3 catalyst with 15% of Cu loading. The selectivity and yield of hydrogen was 66% and 57% respectively over Cu/ZnO/Al2O3 catalyst with 15% of Cu loading. Selectivity of carbon dioxide is 18% over Cu/ZnO/Al2O3 catalyst with 15% of Cu loading at 300oC.Keywords: alumina oxide catalyst, copper zinc oxide, hydrogen, impregnation Format The file format, physical medium, or dimensions of the resource application/pdf Identifier An unambiguous reference to the resource within a given context http://jurnal.unsyiah.ac.id/RKL/article/view/91 Language A language of the resource eng Publisher An entity responsible for making the resource available Chemical Engineering Department, Syiah Kuala University, Banda Aceh, Indonesia Relation A related resource http://jurnal.unsyiah.ac.id/RKL/article/view/91/86 Source A related resource from which the described resource is derived Jurnal Rekayasa Kimia & Lingkungan; Vol 7, No 3 (2010): Jurnal Rekayasa Kimia & Lingkungan 2356-1661 1412-5064 Title A name given to the resource Pembuatan Katalis Cu/ZnO/Al2O3 untuk Proses Steam Reforming Metanol menjadi Hidrogen sebagai Bahan Bakar Alternatif Type The nature or genre of the resource info:eu-repo/semantics/article info:eu-repo/semantics/publishedVersion Peer-reviewed Article Contributor An entity responsible for making contributions to the resource Dublin Core The Dublin Core metadata element set is common to all Omeka records, including items, files, and collections.

Creator An entity primarily responsible for making the resource Husin, Husni Date A point or period of time associated with an event in the lifecycle of the resource 2012-11-15 Description An account of the resource The advantage of palladium modified La-doped NaTaO3 (Pd/La-NaTaO3)semiconductor photocatalyst for enhanced hydrogen generation under irradiation at the ultraviolet range has been investigated. The La-NaTaO3 has been synthesized by sol-gel technique. The palladiums are loaded by impregnation of aqueous palladium nitrate solution. The palladium supported of La-NaTaO3 composites are characterized by transmission electron microscopy (TEM), high-resolution HRTEM (HRTEM), and X-ray absorption spectroscopy (XAS). The HRTEM images indicate that Pd nanoparticles (NPs) aredeposited on the surface of La-NaTaO3. Most of the Pd deposits have diameters ranging from 3 to 4 nm. XAS spectra shows that the Pd-La-NaTaO3 absorbance profiles of the pristine and used samples are overlapped with the Pd foil, indicating that oxidation of the fresh and used cocatalyst was identical in nature with that of the palladium foil. Hydrogen production from pure water irradiation with ultra violet (UV) light source is 1.1 mmol g-1h-1 on La-NaTaO3 photocatalysts. The activity of the La-NaTaO3 up to 8.9 mmol g-1h-1 H2 froman aqueous methanol solution are obtained. The hydrogen evolution on the La-NaTaO3 sample can be further increase of 36.49 mmol g-1h-1 or 4.1 times higher by depositing nanosized Pd as a cocatalyst on the surface photocatalyst. The highest hydrogen generation is observed at 0.15 wt% Pd loading. The higher activity of the Pd/tantalates from aqueous methanol solution is attributed to an important suppressing in the electron–hole pairs recombination due to the effect produced by the presence of La in the NaTaO3 structure as well as by the role of methanol acts as hole-trap and Pd like electron-trap.
