Pd/C electrocatalysts containing VN with different morphology (particles (Pd-VN(particles)/C) and plates (Pd-VN(plates)/C)) were prepared by a simple reduction with sodium borohydride and their electrocatalytic performance for methanol oxidation was investigated. The Pd-VN(particles)/C and Pd-VN(plates)/C performed better activity, stronger resista...
Herein, self-supported hierarchical AuPd alloyed interconnected nanowire networks (AuPd NCNs) were fabricated by a one-pot co-reduction method. Theophylline was acted as the capping and structure directing agents. The product was mainly characterized by a series of techniques such as transmission electron microscopy (TEM), X-ray diffraction (XRD) a...
The chemical modification and organized self-assembly of MXene-based nanocomposites demonstrate critical importance to a wide range of material applications. Herein, we have investigated the preparation of new hierarchical core-shell type MXene-based composite materials for high-efficient dye removal in wastewater treatment via layer-by-layer (LbL)...
Pd/C and Pd-Gd/C catalysts were synthesized and their catalytic performance for methanol electrooxidation in alkaline solution was compared. The structure, morphology and nature of surface species of these catalysts were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM), and X-ray photoelectron spectroscopy (XPS). The...
Pd/C and Pd/Mg-Al-CO3 LDH (Pd/LDH) catalysts were prepared and their catalytic performances for methanol electro-oxidation in alkaline solution were investigated in this work. The result of cyclic voltammograms proves that Pd/LDH has a much higher specific activity than Pd/C. CO stripping results indicate that Mg-Al-CO3 LDH could facilitate the ox...
A high-performance PdRu bimetallic catalyst supported on mesoporous silica nanoparticles (MSN), PdRu/MSN, was prepared by a facile impregnation-hydrogen reduction method. It was found that PdRu/MSN showed 5 times higher activity than that of Pd/MSN towards the liquid-phase hydrogenation of phenol. The catalysts were characterized comprehensively by...
Well-defined core shell gold [email protected] nanocrystals ([email protected]) are facilely prepared by a simple and green wet-chemical method at 25 degrees C. A Good's buffer, 2-[4-(2-hydroxyethyl)-1-piperazinyl] ethanesulfonic acid (HEPES), is used as a reducing agent and a shape-directing agent, while there is no template, seed, organic solvent, or sur...
The Pd-Tb/C catalysts with different Pd/Tb ratios were synthesized by a simple simultaneous reduction reaction with sodium borohydride in aqueous solution. The structure and morphology of those catalysts had been characterized by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The electrocatalytic performance of those catalysts ...
