新型水煤气变换反应催化剂研究进展OA北大核心CSTPCD

The water gas shift reaction is an important process for hydrogen purification,meanwhile,it also plays a significant role in hydrogen generation system for fuel cells.This work summarizes recent research progress on catalyst for water gas shift reaction,including catalytic reaction mechanisms,alternative catalysts as well as the strategies for improving catalytic reaction performance,etc.The reaction mechanisms of water gas shift reaction mainly include associative mechanism,redox mechanism and reforming mechanism,wherein the associative mechanism is mainly refer to formate route and carboxylic acid route.The catalyst systems for the water gas shift reaction mainly include noble metal catalysts and transition metal catalysts.Moreover,the design and development of efficient catalysts for water gas shift reaction can be achieved by dopping additives and optimizing the matal-support interaction.
