Photo-catalytic oxidation of gaseous toluene by Z-scheme Ag3PO4-g-C3N4 composites under visible light: Removal performance and mechanisms

Efficient degradation of VOCs using semi-coke activated carbon loaded ternary Z-scheme heterojunction photocatalyst BiVO4–BiPO4–g-C3N4 under visible light irradiation

“…45 The characteristic peaks observed for pure g-C 3 N 4 at 13.1 and 27.4 correspond to (002) and (100) crystal planes, respectively. 46 In the spectra of BiPO 4 –BiVO 4 –g-C 3 N 4 /SAC complexes, the peaks at 18.3, 18.9, 22.2, 22.8, 25.2 and 30.7 correspond to the (100), (001), (110), (011), (020) and (111) crystal faces of the monoclinic phase BiPO 4 , respectively. The peaks at 19.0, 28.8, 28.9 and 30.5 correspond to the (011), (013), (112) and (004) crystal faces of the monoclinic phase BiPO 4 , respectively, and the peaks at 13.1 and 27.4 corresponding to the (002) and (100) crystal planes of pure g-C 3 N 4 , respectively.…”

Kill two birds with one stone: simultaneous removal of volatile organic compounds and ozone secondary pollution by a novel photocatalytic process

“…Nevertheless, the limited surface area and rapid formation of photogenerated carrier complexes in pure g-C 3 N 4 impede its broader use in photocatalysis. 33,34 Moreover, pure g-C 3 N 4 cannot be directly utilized for the production of active substances from O 3 . To tackle these issues, specialists have improved the application of g-C 3 N 4 in photocatalysis by making changes to its shape and structure, incorporating different elements, and creating heterojunctions.…”
