High-entropy-perovskite subnanowires for photoelectrocatalytic coupling of methane to acetic acid.

ABSTRACT: The incorporation of multiple immiscible metals in high-entropy oxides can create the unconventional coordination environment of catalytic active sites, while the high formation temperature of high-entropy oxides results in bulk materials with low specific surface areas. Here we develop the high-entropy LaMnO₃-type perovskite-polyoxometalate subnanowire heterostructures with periodically aligned high-entropy LaMnO₃ oxides and polyoxometalate under a significantly reduced temperature of 100 ^oC, which is much lower than the temperature required by state-of-the-art calcination methods for synthesizing high-entropy oxides. The high-entropy LaMnO₃-polyoxometalate subnanowires exhibit excellent catalytic activity for the photoelectrochemical coupling o
