氮化碳负载AgPd合金催化剂的甲酸分解制氢性能

Hydrogen Production from the Decomposition of Formic Acid over Carbon Nitride-Supported AgPd Alloy Nanoparticles

本文以氮化碳为载体,使用超声辅助液相还原法制备了氮化碳上负载的AgPd纳米催化剂,并将其应用到甲酸分解制氢反应中。利用XRD、SEM和TEM对催化剂进行了表征,考察了不同甲酸钠加入量条件下催化剂的甲酸脱氢性能。结果表明,催化剂为片状结构,AgPd合金纳米粒子均匀地分散在载体上,甲酸钠的加入量显著提高了催化剂的性能。

In this paper, the AgPd nanoparticle supported on carbon nitride was prepared by ultrasonic assisted liquid phase reduction and applied to the decomposition of formic acid for hydrogen generation.The structure properties of the AgPd/CN were wellcharacterized by XRD, SEM and TEM.The catalyst showed sheet structure, AgPd alloy nanoparticles were dispersed on the carbon nitride and the addition of sodium formate significantly improveed the catalytic performance.
