【摘要】 <正>Supported noble metal catalysts are widely used in many chemical transformation processes that are critical to our society, whose maximized atom utilization of precious metals and optimized catalytic properties are required by sustainable chemistry [1,2].Against this back drop, the emergence and rapid development of single-atom catalysts (SACs) in the past few years have energized the heterogeneous catalysis community. Broad applications of SACs in gas phase catalysis, liquid phase catalysis, electrocatalysis,更多还原
