Emerging Solar Photocatalysis

The special issue of “solar photocatalysis” has captured great attention and support from active researchers in the photocatalysis field. A total 55 papers have been accepted for publication. Thus, this is divided into two parts first part published 2nd Solar RRL 2021, which consisted 2 progress reports, 12 reviews 15 full articles. Herein, we present second that includes 1 report, 14 reviews, 9 articles communications. These 26 are mainly related to design, fabrication, characterization, mechanistic studies photocatalytic materials. Among them, 10 concerned with two-dimensional (2D) photocatalysts; 5 involve one-dimensional (1D) deal hierarchical photocatalysts, rest mixed-anion materials, intrinsic spontaneous polarization electric field, time-resolved X-ray absorption technique so on. Recently, 2D layered photocatalysts under a research spotlight solar-to-fuel conversion due their large surface area abundant exposed catalytic sites.
