High efficiency visible-light-driven Fe2O3-xS /S-doped g-C3N4 heterojunction photocatalysts: Direct Z-scheme mechanism

Z‐Scheme Photocatalytic Systems for Carbon Dioxide Reduction: Where Are We Now?

“…Due to those aforementioned virtues,t he artificial Zscheme photocatalytic systems have been extensively explored in pollutant degradation, [42][43][44] water splitting, [45][46][47] nitrogen fixation, [48,49] organic synthesis [50] and so forth. In particular,Z -scheme CO 2 reduction has become one of the hottest topics and been exhaustively explored ( Figure 4) in recent years.…”

Facile synthesis of bimodal macroporous g-C3N4/SnO2 nanohybrids with enhanced photocatalytic activity

“…Carbon-based materials stand out as an exciting porous structure, and the pores can be produced and tuned during the carbonization of large molecules (e.g., polymers, biomolecules). Graphitic carbon nitride (g-C 3 N 4 ), in particular, has emerged as a front runner because of its suitable bandgap ($2.7 eV), chemical stability, as well as the ease of making thin-layer nanosheets and porous structures [16,[28][29][30][31][32][33][34][35]. So far, porous g-C 3 N 4 has shown great photocatalytic capabilities in visible-light water splitting, CO 2 capture, disinfection and etc.…”

2D/2D heterostructured photocatalyst: Rational design for energy and environmental applications

“…As a result, the optimal g-C 3 Z-scheme 2D/2D photocatalysts (Fig. 9c) can not only hold the attractive 2D/2D contact mode but also benefit from the Z-scheme photocatalytic system which can attain higher redox capacities than the traditional heterojunction [145][146][147][148][149]. She et al [150] synthesized an α-Fe 2 O 3 /g-C 3 N 4 2D/2D Z-scheme hybrid photocatalyst, in which the CB electrons of α-Fe 2 O 3 could easily jump to the VB of g-C 3 N 4 and recombine with the photoinduced holes in the VB of g-C 3 N 4 (Fig.…”
