Atom Doping Engineering of Metal/Carbon Catalysts for Biomass Hydrodeoxygenation

Developing novel and efficient hydrodeoxygenation (HDO) catalysts plays a crucial role on biomass utilization from green and sustainable points of view. In the past, carbon materials were recognized as ideal catalyst carriers due to their fascinating properties including tunable surface structure and excellent chemical and thermal stability. Recently, the newly emerging metal/heteroatom-doped carbon catalysts have arguably experienced tremendous advances and gained widespread interest in view of the fact that heteroatom doping can further tailor the properties of carbon and introduce various metal–carrier interactions, resulting in superior HDO catalyst performance compared to pristine metal/carbon catalysts. In this perspective, we focus on the synthesis strategies for metal/heteroatom-doped carbon catalysts, the property effects of heteroatom doping, and catalytic applications through these fascinating catalysts in biomass HDO. Notably, we try to elucidate the doping effects through a summary of the mechanisms, thereby providing guidance for the rational design of advanced HDO catalysts for biomass catalysis.
