Integrating Ti3C2Tx MXene nanosheets (Ti3C2Tx NSs) as an efficient cocatalyst with MAPbI3 microcrystals results in superior MAPbI3-Ti3C2Tx NS composite photocatalysts for H2 evolution from MAPbI3-saturated HI aqueous solution using visible light. The best MAPbI3 (100 mg)-Ti3C2Tx NS (10 mg) composite exhibits a H2 evolution rate of 63.6 μmol h-1, which is 43 times higher than that of pristine MAPbI3, and a stable H2 evolution activity over a 120 h repeating reaction.
将Ti3C2Tx MXene纳米片（Ti3C2Tx NSs）作为高效助催化剂与MAPbI3微晶相结合，可制备出优异的MAPbI3-Ti3C2Tx NS复合光催化剂，用于在可见光下从MAPbI3饱和氢碘酸水溶液中析氢。最佳的MAPbI3（100毫克）-Ti3C2Tx NS（10毫克）复合材料的析氢速率为63.6微摩尔/小时，比原始MAPbI3高43倍，并且在120小时的重复反应中具有稳定的析氢活性。
