Fabrication of sulfur-doped g-C 3 N 4 /Au/CdS Z-scheme photocatalyst to improve the photocatalytic performance under visible light

Fabrication of conductive and high-dispersed Ppy@Ag/g-C3N4 composite photocatalysts for removing various pollutants in water

“…(2), (3)). On one hand, due to the Ag nanoparticles anchored between g-C 3 N 4 and Ppy acted as electron transfer mediator [57], the weak reductive electrons of Ppy easily flow into metal Ag very fast (electron transfer I: Ppy → Ag) (Eq. (4)), which is faster than the electron−hole recombination between the LUMO and HUMO of Ppy.…”

Facile synthesis of Z-scheme graphitic-C3N4/Bi2MoO6 nanocomposite for enhanced visible photocatalytic properties

“…The Z-scheme semiconductor nanocomposites exhibit better photocatalytic activity than single semiconductor for the well separation of electrons and holes and also reduction of their recombination. To further improve the photoactivity of g-C 3 N 4 , researchers have coupled g-C 3 N 4 with other inorganic semiconductors, such as, BiVO 4 /g-C 3 N 4 [22], g-C 3 N 4 /Bi 2 MoO 6 [23], g-C 3 N 4 /Bi 2 WO 6 [24], g-C 3 N 4 /MoO 3 [25], SnO 2-x /g-C 3 N 4 [26], WO 3 /g-C 3 N 4 [27], Bi 2 O 3 /g-C 3 N 4 [28], g-C 3 N 4 /Au/CdS [29]. [33], and Ag 2 CO 3 /Ag/AgBr [34].…”

Solar‐Inspired Water Purification Based on Emerging 2D Materials: Status and Challenges

“…The efficiency of photocatalysis is generally lower than that of electrocatalysis due to the accompanying energy loss and the additional steps of generating the optical carrier. Therefore, some strategies to get high photocatalytic performance usually include changing bandgap, forming Z‐scheme structure, or adding cocatalysts, etc. The purpose is to promote the photo‐induced carrier separation and improve light absorption …”
