Novel Z-scheme visible-light-driven Ag₃PO₄/Ag/SiC photocatalysts with enhanced photocatalytic activity

Abstract

The excellent photocatalytic activity of Ag3PO4/Ag/SiC can be ascribed to the efficient separation of photogenerated electron–hole pairs through the Z-scheme.

The Properties and Activity of TiO2/beta‐SiC Nanocomposites in Organic Dyes Photodegradation

“…These findings are also in line with the different nanocomposite b-SiC-Ag 3 PO 4 /Ag/SiC. This catalyst was also reported as responsible for effective photodegradation of diluted methyl orange and phenol (both at the initial concentration of 10 ppm) solutions (21). Importantly, in all these cases, the catalyst concentration was relatively high (1 g L À1 ).…”

Enormous enhancement in photocatalytic performance of Ag3PO4/HAp composite: A Z-scheme mechanism insight

“…Thus, much attention has been employed to develop a simple and effective technology to improve efficiency of photoinduced electrons for Ag 3 PO 4 system. Constructing a hybrid or heterojunction between Ag 3 PO 4 and another semiconductor with proper band structure such as Ag 3 PO 4 /TiO 2 [13], Ag 3 PO 4 /g-C 3 N 4 [10,14], Ag 3 PO 4 /SnO 2 [15], Ag 3 PO 4 /Ag/SiC [16], Ag 3 PO 4 -Graphene [17], and P25/Ag 3 PO 4 /graphene oxide [18] can enhance the photocatalytic activity and stability of Ag 3 PO 4 in the photocatalytic degradation of organic pollutants and bacteria. Moreover, the particles size of Ag 3 PO 4 has obvious effect on the efficiency of photodegradation [19].…”

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

“…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]. As similar with the heterojunction type system, making good use of the spatial isolation of photogenerated electrons and holes is still important for advanced photocatalyst design.…”
