| 摘 要： | 以ISOBAM-104为保护剂,采用共还原法制备了一系列不同组成的Rh/Co双金属纳米颗粒(BNPs)。采用紫外-可见吸收光谱、透射电镜及高分辨透射电镜对纳米颗粒的结构及组成进行了表征。结果表明,所制备的Rh/Co BNPs的粒径小于6.0nm,具有合金结构。催化制氢实验结果表明,Rh_(20)Co_(80)BNPs具有最高的催化制氢活性,其TOF值可高达12880mol-H_2·h~(-1)·mol-Rh~(-1),远高于Rh和Co单金属纳米颗粒的催化活性。

| Abstract: | A series of Rh/Co bimetallic nanoparticles (BNPs) were synthesized by rapid injection of KBH4 using ISOBAM-104 as protective reagent. UV-vis, TEM and HRTEM were used for characterization of the structure and composition of the prepared BNPs. It showed that Rh/Co BNPs are alloy structure, and that the particle size of as-prepared BNPs are less than 6.0 nm. The catalytic activity of the prepared Rh/Co BNPs are higher than that of Rh or Co monometallic nanoparticles, and Rh20Co80 BNPs possessed the highest TOF of 12880 mol-H2.h-1.mol-Rh-1. |
