WebThe core of the photocatalytic material has a size range of 80–100 nm, while the core–shell nanoparticles have a size of around 130 nm. The hydrodynamic radius of the photocatalytic core and the shell was investigated, and a similar increase in size was observed from 200 to 250 nm ( Figure S1 ). WebThe efficient separation of photoexcited electrons and holes is crucial for improving the activity of photocatalytic hydrogen evolution. Herein, an efficient core–shell p–n heterojunction of ZnIn2S4@CuInS2 microflowers has been devised and fabricated by two-step hydrothermal method. The results revealed that the marigold-like microspheres of …
