摘要

低温水煤气变换反应（WGSR）是制氢工业的关键环节。针对传统催化剂低温活性差和贵金属催化剂贵金属用量高的问题，采用简单混合法将Pt盐与Cu盐混合后加入钼酸铵中超声、焙烧，制备了Cu改性Pt@AM催化剂用于低温催化WGSR。结果表明，在Pt@AM中加入少量Cu不仅有利于

-MoC结构的形成，还能增强金属间相互作用，调节活性位点分布，从而提升催化剂催化活性。其中，0.05%Pt-0.5Cu%@AM在温度200 ℃、原料气

Abstract

Low-temperature water-gas shift reaction (WGSR) is a key bridge in hydrogen production industry. In response to the poor low-temperature activity of traditional catalysts and the high metal content of noble mental catalysts

a simple mixing method was used to mix Pt salt and Cu salt

and then add them to ammonium molybdate for ultrasonic and calcination to prepare Cu-modified Pt@AM catalysts in low-temperature WGSR. The results show that adding a small amount of Cu to Pt@AM not only facilitates the formation of

-MoC

but also enhances the interaction between metals

adjust the distribution of active sites

and thus improves the catalytic activity of catalysts. Among them

0.05%Pt-0.5Cu%@AM catalyst shows a high CO conversion rate of up to 73.5% and a H

yield of 38.6% after 1 h reaction under the reaction conditions of temperature of 200 ℃

) = 2:5:18 and space velocity of 40000 mL/(g·h)

indicating that Cu modification significantly improves the catalytic activity of noble metal Pt based catalysts. This study reveals the structure-activity relationship of Cu modification to improve catalytic activity of catalysts

and provides a theoretical basis for designing low-temperature WGSR catalyst with high activity.
