摘要

甲醇是一种重要的基础化工原料和能量载体，利用CO

催化加氢制甲醇在一定程度上可以缓解能源短缺问题，同时也符合绿色经济发展需求。比较了3种不同制备方法（共沉淀法、水热法和溶胶凝胶法）制备的CuZnGa催化剂在CO

加氢制甲醇反应中的性能差异，并结合XRD、TEM、N

吸/脱附、XPS、CO

-TPD和H

-TPR等对催化剂的物化性质进行了系统分析。结果表明，共沉淀法制备的催化剂具有最大的比表面积（49.0 m

/g）和最高的氧空位相对含量（19.8%），可提供更多活性位点，显著促进CO

的活化与转化。在260 ℃、4 MPa和7500 mL/(g·h)条件下反应10 h，共沉淀法制备催化剂的CO

转化率可达15.8%，甲醇选择性可达56.4%，表现出最优的催化性能。

Abstract

Methanol is an important basic chemical feedstock and energy carrier. Utilizing CO

catalytic hydrogenation to methanol can alleviate energy shortages to a certain extent while also aligning with the demands of green economic development. CuZnGa catalysts were synthesized using three different methods (co-precipitation

hydrothermal and sol-gel methods). Their catalytic performances were systematically compared in CO

hydrogenation to methanol reaction. Characterization techniques including XRD

TEM

adsorption/desorption

XPS

-TPD

and H

-TPR were used to analyze their physicochemical properties. The results show that among three catalysts

the catalyst prepared by co-precipitation exhibits largest specific surface area (49.0 m

/g) and highest relative oxygen vacancy (19.8%)

providing abundant active sites for CO

activation and conversion. Under reaction conditions of 260 ℃

4 MPa and 7500 mL/(g·h) for 10 h

it achieves CO

conversion rate of 15.8% and methanol selectivity of 56.4%

outperforming other catalysts.
