英文摘要	Organic-inorganic hybrid perovskites have demonstrated great potential in solar cell fabrication due to excellent optoelectronic properties. However, their success in solar cells has been hardly translated to producing solar fuels because of instability issues and serious charge recombination at the nanoscale domain. Herein, we show for the first time that organic-inorganic hybrid perovskite methylammonium lead bromide (MAPbBr(3)) nanocrystals can be stabilized in aqueous HBr solution and achieve photocatalytic H-2 production reaction under visible light. More impressively, by hybridizing MAPbBr(3) with Pt/Ta2O5 and poly(3,4-ethylenedioxythiophene) polystyrenesulfonate (PEDOT:PSS) nanoparticles as electron- and hole-transporting motifs, respectively, drastically enhanced charge transportation on MAPbBr(3) and improved catalysis were achieved. As a consequence, the rate of photocatalytic hydrogen evolution on pristine MAPbBr(3) was increased by ca. 52 times by introducing dual nanoscale charge-transporting highways, achieving an apparent quantum efficiency of ca. 16.4% for H-2 evolution at 420 nm.
