Cluster models embodying the periodicity and symmetry of atomic arrangement on the surface of g-Al O , as a support, 2 3 Ž . have been applied to discuss the dispersion state of metal oxide i.e., MoO , NiO, or CuO on the basis of the incorporation 3 model from the theoretical chemistry’s point of view. The preference occupation of the tetrahedral or octahedral vacant sites available on the surf...

Standard sacrificial template synthesis allows metal oxide nanotubes to be produced from ZnO nanowires. In spite of their high interest in several technological fields, the low surface area of these nanotubes is a drawback for most applications. Here we report for the first time the sacrificial template synthesis of stainless steel wire-mesh (SSWM) supported metal oxides of high technological i...

Abstract Nanotechnology is a completely unique branch of technology that offers with substances in very small size between (1–100 nm) various crystal shapes. Metals have ability to produce large number oxides. These metal oxides play major role many areas chemistry, physics, material science and food science. In this research, Zinc Oxide (ZnO) Copper (II) oxide nanoparticles were synthesized vi...

Copper oxides have been of considerable interest as electrocatalysts for CO2 reduction (CO2R) in aqueous electrolytes. However, their role as an active catalyst in reducing the required overpotential and improving the selectivity of reaction compared with that of polycrystalline copper remains controversial. Here, we introduce the use of selected-ion flow tube mass spectrometry, in concert with...

In the present work, we report the synthesis of binary nano metal oxides such as Zinc /Copper Oxide via novel dry synthetic methods such as thermal decomposition of oxalate precursor. The synthesis route involves facile solid-phase mechanochemical activation of a physical mixture of simple copper/zinc salts and oxalic acid, followed by calcination of the as-ground oxalate precursors at 450◦C. X...

Recently, bulk superconductivity at ambient pressure in polycrystalline pressed samples of an organic metal a,-(BEDT-TTF),I, was observed."' This is a remarkable fact because this finding shows that organic superconductors can in principle be used for the production of electronic devices, such as squids, and might even be suitable for the preparation of superconducting cables similar to the hig...

Spatially well-distributed copper-zinc oxides supported on mesoporous silica (SBA-15 and commercial silica gel) showed high adsorption capacity for hydrogen sulfide (as high as 80 mgS/gsorbent) and stability during cyclic adsorption-regeneration process. 2014 Elsevier Inc. All rights reserved.
