Solar-driven selective upgrading of lignocellulosic biomass-derived alcohols to value-added chemicals and clean fuel hydrogen(H2)shows great potential for tackling the energy crisis and environmental pollu-tion issues.Here,we construct a MAPbBr3/ReS2 heterostructure by embedding distorted tetragonal(1T)phase ReS2 nanoflowers into large-sized MAPbBr3 for green value-added utilization of biomass-derived alcohols.The embedded structure effectively enlarges the contact interface between the ReS2 and the MAPbBr3,and importantly,induces a strong built-in electric field aligned between the spatially well-defined MAPbBr3 and ReS2 nanoflowers.Moreover,the distorted 1T phase ReS2 with low work function well matches the energy band of MAPbBr3,forming a heterostructure with a downward band bending at the interface.These features empower the MAPbBr3/ReS2 photocatalyst with high capability to promote charge separation and expedite the surface redox reaction.Consequently,optimal BAD and H2 production rates of about 1220 μmol h-1 g-1 are realized over a MAPbBr3/ReS2 2％sample,which are approximately 9 times greater than those of blank MAPbBr3.This work demonstrates the great potential of constructing an embedded transition metal dichalcogenide@metal halide perovskites heterostructure with downhill interfacial charge transfer for photocatalytic upgrading of biomass-derived alcohols.
