摘要

为明确Cu/Zn摩尔比对纯 Cu-Zn 催化剂 CO

加氢制甲醇性能及反应机制的影响，本研究聚焦Cu-Zn本征协同作用（排除载体与助剂干扰），开展性能调控分析。以共沉淀法制备Cu/Zn摩尔比分别为 0.5、1.0、1.5、2.0、2.5的纯 Cu-Zn催化剂，通过固定床评价催化性能、采用原位漫反射红外光谱（in-situ DRIFTS）解析反应中间物种与路径，同时进行稳定性测试。结果显示：Cu/Zn＝1.5时催化剂性能最优，CO

转化率达 29.8%、甲醇选择性93.8%、收率28.0%，且长期稳定性良好、Cu 颗粒烧结程度低。in-situ DRIFTS证实其可高效生成HCOO 活性中间物种，促进甲醇生成并抑制CO副产物产生。本研究在无载体Cu-Zn体系中首次建立“Cu/Zn 摩尔比-催化剂结构-催化性能-反应机制-稳定性”完整关联，明确纯Cu-Zn体系中Cu/Zn摩尔比的定量调控作用，为简化型催化剂设计优化提供实验支撑。

Abstract

To clarify the effects of Cu/Zn molar ratio on the catalytic performance and reaction mechanism of pure Cu-Zn catalysts for CO

hydrogenation to methanol

this study focuses on the intrinsic synergistic effect of Cu and Zn by eliminating the interference of supports and additives to conduct performance regulation analysis. Pure Cu-Zn catalysts with Cu/Zn molar ratios of 0.5

1.0

1.5

2.0 and 2.5 were synthesized via the co-precipitation method. Their catalytic performances were evaluated in a fixed-bed reactor

reaction intermediates and pathways were identified by in-situ diffuse reflectance infrared fourier transform spectroscopy (in-situ DRIFTS)

and long-term stability tests were also carried out. The results indicate that

the catalyst with a Cu/Zn molar ratio of 1.5 exhi

bits the optimal catalytic performance

achieving a CO

conversion of 29.8%

methanol selectivity of 93.8% and methanol yield of 28.0%. It also possesses excellent long-term stability with low sintering degree of Cu nanoparticles. In-situ DRIFTS results confirm that this catalyst can efficiently generate HCOO active intermediates

which facilitates methanol formation and suppresses the production of CO by-products. For the first time

this work establishes a complete correlation among Cu/Zn molar ratio

catalyst structure

catalytic performance

reaction mechanism and stabilityin the carrier-free Cu-Zn system

and clarifies the quantitative regulation effect of Cu/Zn molar ratio in pure Cu-Zn systems. This study provides experimental guidance for the rational design and optimization of simplified catalysts.
