Upcycling endogenous Fe from coal gasification slag waste into a cocatalyst for the photocatalytic H evolution reaction

Rather than regarding endogenous Fe in coal gasification slag (CGS) as waste, it could be considered as a potential source to develop an efficient catalyst for energy conversion reactions. Herein, we report an in situ exsolution strategy for upcycling endogenous Fe in CGS waste into a supported Fe 2...

Description
Summary:Rather than regarding endogenous Fe in coal gasification slag (CGS) as waste, it could be considered as a potential source to develop an efficient catalyst for energy conversion reactions. Herein, we report an in situ exsolution strategy for upcycling endogenous Fe in CGS waste into a supported Fe 2 P cocatalyst via the low-temperature phosphidation for efficient solar H 2 evolution reaction (HER). During phosphidation, ultrasmall Fe 2 P nanoparticles (
