工业气体中微量氧深度脱除催化剂研究进展
Advances in research on catalysts for deep removal of trace oxygen in industrial gases
摘要
Abstract
In industrial gas deoxidation technology,catalytic deoxidation methods have been widely applied due to their high efficiency and deep removal capability.The development of cost-effective,highly active,selective,and durable catalysts is pivotal for catalytic deoxidation technology.This article reviews the current research on gas deoxidation catalysts,elucidating their mechanisms of catalytic deoxidation across various scenarios.It summarizes the influence patterns of active components,promoters,and supports on catalytic deoxidation performance from the perspective of catalyst structural design.Low-temperature activity,poison resistance,and long-term stability are important objectives in the development of deoxidation catalysts.The strategies for constructing highly active and stable deoxidation catalysts are summarized,mainly including physical methods of spatial confinement and chemical methods such as alloying of active centers and strong metal-support interactions.Finally,based on the current research and application status of gas deoxidation catalysts,the study highlights non-noble metal deoxidation catalysts,(hydro)thermally stable single-atom deoxidation catalysts,and multifunctional deoxidation catalysts as significant trends in the future development of deoxidation catalysts.关键词
