The occurrence of cation exchange with different crystal structures is limited. We propose a new descriptor, the parallel six-sided subunit (PSS), to synthesize transition metal sulfides with crystal structure selectivity by gas-phase cation exchange-induced topological transformation. Powered by precise synthetic control, the photocatalytic hydrogen evolution performance is improved by 36.2 times after band gap engineering.

通过气相阳离子交换诱导拓扑转变合成带隙可调的过渡金属硫化物

具有不同晶体结构的阳离子交换的发生是有限的。我们提出了一种新的描述符，即平行六面亚基 (PSS)，通过气相阳离子交换诱导的拓扑转变合成具有晶体结构选择性的过渡金属硫化物。在精确的合成控制下，带隙工程后的光催化析氢性能提高了36.2倍。
