A new strategy for insulators to improve the ability of semiconductors to reduce Cr (VI)

“…At present, the application of insulator materials in the field of photocatalysis is mainly in the field of organic matter degradation and gas air purification. Qi designed a one-step calcination method to prepare g-C 3 N 4 /CaCO 3 photocatalyst and CaCO 3 , increasing the efficiency of nicotine degradation of g-C [4] . Han designed a new SrTiO 3 /SrCO 3 structure by one-step hydrothermal method.…”

Cyano‐Rich g‐C3N4 in Photochemistry: Design, Applications, and Prospects

“…[4,19,20] Among them, cyano-modified carbon nitride materials have received much attention due to the fact that cyano as a strong electron-absorbing group with electron storage capacity (This is a capability that all other defects and functional group modifications above do not have) into g-C 3 N 4 's framework can further improve light absorption, adjust the energy band structure, change semiconductor type, increase the polarization rate, electron density, active site concentration in the structure, promote oxygen activation ability, and drive the migration of photogenerated carriers to enhance photocatalytic performance. [21][22][23][24][25][26][27][28][29][30][31][32][33][34][35] cyano-rich g-C 3 N 4 not only has excellent performance in the field of photocatalysis, but also has been applied in other photochemical fields, such as photoelectrocatalysis, photoelectric detection, photoluminescence, photochromic, etc. [36][37][38][39][40][41][42][43][44] In this review of cyano-rich g-C 3 N 4 on photochemistry, the synthesis methods of cyano-rich g-C 3 N 4 and the means of detecting the position/quantity of cyano are first comprehensively introduced; then, the applications of cyano-rich g-C 3 N 4 in diverse fields of photochemistry are presented; finally, the methods to optimize the photochemical properties of cyano-rich g-C 3 N 4 are summarized based on the current research progress and the main limitations.…”
