Abstract

AbstractWe use MOFs material as precursor to synthesize carbon based two‐dimensional (2D) materials loaded with In2S3−In2O3 (In−S−O) nanoparticles. The In−S−O nanoparticles have exhibited Janus architecture composed of two compounds with different crystal structures that are combined in‐plane on 2D carbon material surface. The excellent properties of this in‐plane Janus material include 2D nanoarchitecture and its Janus properties formed by combining two different crystal structures. It has exhibited excellent electrochemical performances due to its abundant electrochemical active sites and large specific surface area. According to experiments, the electron transfer number of the material for two‐electron oxygen reduction is about 2.4, and the hydrogen peroxide yield is 32 mg/h cm2. In the further test of liquid flow electrolytic cell, the yield can reach up to 172 mg/h cm2.
