The Z-scheme g-C3N4/3DOM-WO3 photocatalysts with enhanced activity for CO2 photoreduction into CO

Core‐Shell Engineered WO3 Architectures: Recent Advances from Design to Applications

“…The high oxidation potential and visible-light activity of WO 3 in combination with other materials are favorable. [86,87] Recently, a Z-scheme of g-C 3 N 4 nanosheets with WO 3 microspheres was reported to exhibit good performance in CO 2 reduction. The Z-scheme mechanism was similar to the mechanisms discussed in Section 4.1.…”

Reduced graphene oxide-modified Z-scheme g-C3N4/CdS photocatalyst with a staggered structure for the enhanced photoreduction of CO2

“…[18][19][20] The common 2D structure of g-C 3 N 4 has been widely used as a carrier material for building functional materials. [21][22][23] The construction of heterojunctions, element doping, introduction of defects, and other strategies have been used to improve the light absorption capacity, separation and transmission efficiency of photogenerated electrons in g-C 3 N 4 . [24][25][26][27] For example, in our previous work, the construction of a Z-scheme g-C 3 N 4 / Ag 3 VO 4 /rGO heterojunction effectively remedied the problem of the high recombination rate of g-C 3 N 4 electron-hole pairs and improved the utilization of photogenerated electrons in CO 2 reduction.…”

Synthesis of mixed-valence Cu phthalocyanine/graphene/g-C3N4 ultrathin heterojunctions as efficient photocatalysts for CO2 reduction

“…Great efforts have been made to overcome these drawbacks, such as nanostructure design, 12 elemental doping, 13,14 single-atom modification, 15 and constructing heterojunctions with oxides. 16 Very recently, metal phthalocyanines (MPc) have been exploited to combine with CN for constructing organic heterojunctions. For example, ZnPc has been demonstrated to promote the photocatalytic activity of CN for CO 2 reduction or pollution degradation because of its expanded light absorption and charge separation.…”
