Black phosphorous (BP), as a new two-dimensional material, with an adjustable band gap (0.3～2.0 eV) based on the number of layers and high carrier mobility(1000 cm2·V-1·s-1), has been widely concerned in photocatalysis. The strong absorption intensity in visible and near-infrared light regions of BP makes it to be a broad-spectrumresponsive semiconductor photocatalyst, which is an advantage that other materials can‘t match. The high carrier mobility of BP makes it an excellent transport material for photogenerated carrier transfer. Furthermore, the BP nanomaterials have large specific surface area, which can provide abundant reactive sites for photocatalytic reactions, thereby increasing the catalytic efficiency. Currently, BP has been widely studied in the fields of photocatalytic hydrogen production, photocatalytic nitrogen fixation and photocatalytic CO2 reduction, it shows unique advantages and good performance, which means BP is an ideal photocatalyst material. In this review, the latest research progress of BP materials in photocatalysis was reviewed. The structure and basic properties of BP were firstly introduced in detail, and then the preparation methods of BP materials were summarized. The relationship between structure and performance of BP photocatalyst was also discussed. At last, the future development direction of BP for photocatalysis was proposed.
