noble metals deposited on the carbon surface, the platinum is frequently used as a valuable and efficient catalyst [9]. Ageeva et al [9] studied the mechanism and kinetics of the sorption process of platinum, palladium and gold complexes on the BAU activated carbon (AC). The effects of pH and initial concentration of precious metals on the adsorption equilibrium of those metals were investigated......
Atomic simulation on evolution of nano-crystallizaion in amorphous metals WANG Yu(王 宇), WANG Xiu-xi(王秀喜), WANG Hai-long(王海龙) Key Laboratory of Mechanical Behavior and Design of Materials... amorphous Ni-Pd alloys and the temperature effect on the nano-crystallization behavior in amorphous metals were studied. The results show that the small nano-crystalline grain will nucleate and grow......
, and the average diameter of the pore is around 3.5 nm. The nanoplate with mesoporosity is active to methanol electrocatalytic oxidation, and its electrocatalytic property is similar to that of platinum. Key words: tungsten carbide; nanoplate; mesoporosity; electrocatalytic property; platinum similarity 过渡金属碳化物(包括碳化钼,碳化钛,碳化钨,碳化钒等)具有独特的物理化学性能,如机械强度高,导电率高,热稳定和化学稳定性好[1-2],以及较好的催化活性等,这些性能使其受到越来越多的关注.自发现碳化钨(WC)具有类铂电催......

of these metal complexes lies in the optoelectronics areas, such as light-emitting devices (LEDs)[7], chemosensors[8], and photovoltaic devices[9]. Among these complexes, cyclometalated platinum (II) complexes with a square- planar d8 electronic configuration, have displayed their potential applications in light-emitting devices[10-12]. Many cyclometalated homo- or hetero-leptic platinum (II......
