Metal halide perovskites (MHPs) photocatalysts are bi-functionalized with lead sulfide (PbS) and amorphous molybdenum sulfide (MoS_x) co-catalysts on the surface. PbS can passivates the defects of MHPs and MoS_x provides active sites for hydrogen evolution reaction (HER), thus synergistically enhancing the charge transport efficiency and HER catalysis and achieving a superior solar-to-chemical (STC) energy conversion efficiency of 4.63 %.

同时进行缺陷钝化和助催化剂工程可在金属卤化物钙钛矿上实现优异的光催化析氢

金属卤化物钙钛矿（MHP）光催化剂通过表面的硫化铅（PbS）和无定形硫化钼（MoS _x ）助催化剂进行双功能化。 PbS可以钝化MHP的缺陷，而MoS _x为析氢反应（HER）提供活性位点，从而协同增强电荷传输效率和HER催化，实现4.63％的优异的太阳能化学（STC）能量转换效率。
