A series of surface-functionalized gold nanocatalysts are synthesized. Through diazonium chemistry, calix[4]arene molecules grafted at the surface. Sharing same anchoring function and a common backbone, ligands possess distinct terminal chemical functions where length, hydrophobic nature, oxygen affinity varied. Thanks to versatility platform, this paper only focuses on molecular tuning solid/l...

In this study simple catalytic test experiment was performed in a flask of rotary evaporator for dechlorination of nitrochlorobenzene (NCB) over two samples of Ni/LaAl2 O3 nanocatalysts (C1 and C2). In the reaction, Ni acts as a catalyst to collect hydrogen gas in aqueous solution and dissociate it to produce active hydrogen atoms for replacing the chlorine. The catalysts were characterized by ...

Impregnation is the most commonly used approach to prepare supported metal catalysts in industry. However, this method suffers from formation of large particles with uneven dispersion, poor thermal stability, and thus unsatisfied catalytic performance. Here, we demonstrate that self-pillared MFI zeolite (silicalite-1 ZSM-5) nanosheets larger surface area abundant Si-OH groups are ideal supports...

The electroreforming of glucose/xylose mixtures has been evaluated at Pd1-xAux/C anodes in 0.10 mol L−1 NaOH electrolyte. catalysts synthesized by a wet chemistry route are comprehensively characterized physicochemical and electrochemical techniques. From linear scan voltammetry situ Fourier transform infrared spectroscopy measurements, it was shown that the Pd0.3Au0.7/C material led to best el...
