This project aims to develop nano-catalysts with high catalytic activity and rapid gas detachment properties for efficient fuel gas production. Heterogeneous electrocatalytic gas evolution reactions are important for clean energy generation and storage technologies, but high overpotentials caused by slow gaseous products’ detachment from catalyst surface severely hinder their efficiencies. Expected outcomes include insights into gas bubble formation and evolution during electrocatalysis, effective catalyst structures to mitigate negative effects of gas bubble formation, and improved catalytic efficiency of gas evolution reactions and develop high performance electrocatalysts for fuel gas production.

该项目旨在开发具有高催化活性和快速气体分离特性的纳米催化剂，用于高效的燃气生产。多相电催化析气反应是清洁能源生产和储存技术的重要组成部分，但由于气体产物从催化剂表面缓慢脱离而导致的过电位过高严重阻碍了其效率。预期成果包括深入了解电催化过程中气泡的形成和演变，有效的催化剂结构，以减轻气泡形成的负面影响，提高气体析出反应的催化效率，并开发用于燃料气生产的高性能电催化剂。
