采用液相化学还原法制备了系列用于一氧化碳、水及氧气直接法制过氧化氢的环境友好纳米Cu/Al2O33催化剂,并用TEM,XRD和N2O化学滴定等手段对催化剂中纳米金属铜的结构及性质进行了表征.研究结果表明,Cu/Al2O33催化剂在CO/H2O/O2直接法制H2O2反应中呈现出显著的纳米尺寸效应:当金属铜纳米晶粒平均尺寸为15 nm时,有高达0.236 mmol·(g-cat)-1·h-1的H2O2生成速率.

A series of environmentally benign nanocrystalline Cu/Al2O3 catalysts for the direct formation of H2O2 from CO, H2O and O2 have been developed by a novel liquid-phase chemical reduction method and characterized by TEM, XRD, and N2O titration. A maximum H2O2 formation rate of 0 236 mmol·(g-cat)-1·h-1 was achieved over the catalyst with average Cu particle size of 15 nm, suggesting the presence of a significant size effect on the performance of the Cu/Al2O3 catalysts.

Key words: environmentally benign, nanocrystalline Cu/Al2O3 catalyst, direct production, carbon monoxide, hydrogen peroxide
