, Changsha 410082, China Received 9 December 2014; accepted 15 July 2015 Abstract: Ag-based nanocatalysts exhibit good catalytic activity for the electrochemical reduction of organic halides. Ag-Ni alloy... positively, and increase the catalytic activity of Ag-Ni NPs. However, when the Ni content reaches a certain value, the catalytic activity of Ag-Ni NPs decreases. Meanwhile, the synergistic catalytic......
and then washed several times with methanol. After drying, it was re-used to test the catalytic recyclability. Figure S3 Kinetic curves of Co3S4/NC-400 and CoSx/NC-500 Figure S4 XPS high-resolution N... possesses higher degree of S defects and larger specific surface areas, can achieve high conversion, selectivity and stability for catalytic reduction of nitro compounds into amines under mild reaction......
J. Cent. South Univ. (2016) 23: 39-43 DOI: 10.1007/s11771-016-3046-8 Kinetic study on leaching of nickel from Turkish lateritic ore in nitric acid solution Tevfik AGACAYAK, Veysel ZEDEF, Ali ARAS... in range of 0.1-2 mol/L on nickel dissolution rate. The kinetic analysis shows that the nickel dissolution from lateritic ore could be described by diffusion model. The activation energy (Ea......
Microwave-assisted synthesis of L-cysteine-capped nickel nanoparticles for catalytic reduction of 4-nitrophenolNazar Hussain Kalwar,Ayman Nafady,Razium Ali Soomro,Sirajuddin,Syed Tufail Hussain... of reductant(Na BH4)within reaction time of 40 s. In contrast, Raney nickel in similar sample environments shows only 25.5% reduction.The kinetic and energetic behaviours of cyst-Ni NPs were also studied......

was measured under mixed gas. The results show that, for the Pd/TiZrNiCo, the thinner the Pd membrane, the better the poisoning resistance and hydrogen adsorption kinetic properties. The pulverization of Pd... pulverization. Therefore, the hydrogen absorption-desorption repeating leads to the fluctuation of hydrogen absorption quantity of Pb/TiZrNiCo. Kinetic model for hydrogen absorption under pure......
