Review on Nanoscale Bi-based Photocatalyst


Nanoscale Bi-based photocatalysts are promising candidates for visible-light-driven photocatalytic environmental remediation and energy conversion. However, the performance of bulk bismuthal semiconductors is unsatisfactory. Increasing efforts have been focused on enhancing the performance of this photocatalyst family. Many studies have reported on component adjustment, morphology control, heterojunction construction, and surface modification. Herein, recent studies on these fields, including doping, changing stoichiometry, solid solution, ultrathin nanosheet, hierarchical and hollow architecture, conventional heterojunction, direct Z-scheme junction, and surface modification of conductive materials and semiconductors, are reviewed. The progress in enhancement mechanism involving light absorption, band structure tailoring, and separation and utilization of excited carriers, was also introduced. The challenges and tendencies in the studies of nanoscale Bi-based photocatalysts were discussed and summarized.
