Enhance the Activity of CO2 Hydrogenation to Methanol Over La2O3 Promoted In2O3-ZrO2 Catalysts
In this study, indium–zirconium catalysts with varying levels of lanthanum doping were synthesized via a hydrothermal method to evaluate their performance in the hydrogenation of carbon dioxide to methanol. To elucidate the effects of lanthanum incorporation, a comprehensive set of characterization techniques and catalytic evaluations was employed to examine structural modifications, surface properties, and catalytic activity. The results demonstrate that optimal lanthanum doping significantly improves both activity and selectivity, achieving a maximum space–time yield of 7.22 mmol·h− 1·gcat−1. Detailed analyses revealed the influence of lanthanum on crystal phase composition, specific surface area, reducibility, adsorption behavior, and surface elemental distribution. A potential reaction mechanism is also proposed. This work provides valuable insights into the rational design of high-performance catalysts for CO₂ hydrogenation to methanol.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
