“…As the reduction potential of CH 4 (CO 2 /CH 4 ≈−0.24 V, NHE) is more positive than that of (CO 2 /CO≈−0.53 V, NHE), the process of photocatalytic conversion for CO 2 to CH 4 is more feasible. Consequently, the CO 2 photoreduction process may be summarized as follows [ 59,68,69 ]

{BiOI/MoS}_{2} /CdS + h v \to {BiOI/MoS}_{2} /CdS + {normalh}^{+} + {normale}^{-}

{normalH}_{2} O ⇆ {normalH}^{+} + {normalOH}^{-}

{normalH}_{2} O + {normalh}^{+} \to \cdot OH + {normalH}^{+}

{CO}_{2} + {8 H}^{+} + {8 e}^{-} \to {CH}_{4} + {2 H}_{2} O

{CO}_{2} + {2 H}^{+} + {2 e}^{-} \to CO + {normalH}_{2} O

Efficient photocatalytic CO2 reduction into clean chemical fuels using visible light remains an enormous challenge. Construction of hierarchical heterostructured photocatalysts has gained tremendous popularity due to their distinctive structural characteristics and synergetic effect that they can boost the visible‐light photoactivities. Based on this, a three‐step solvothermal method is proposed to construct hierarchical BiOI/MoS2/CdS heterostructured microspheres. The addition of MoS2 and CdS not only plays a significant role in the improvement of visible‐light absorption, but also works as a carrier electron mediator, inhibiting the recombination of electrons–holes effectively. High CH4 yield (46.22 μmol h−1 g−1) and CO yield (36.98 μmol h−1 g−1) are achieved for BiOI/MoS2/CdS‐0.03 heterostructured microspheres under simulated sunlight irradiation because of the wide solar light‐driven response, abundant active sites and high charge separation ability. Therefore, this study provides an efficient strategy for constructing heterostructured catalysts with remarkable visible‐light response photocatalytic CO2 reduction activity.

“…The Ag and Au can prevent rapid recombination probability, improve the transfer of a generated electron, and enhance the visible light absorption by the surface plasmon resonance, and can be used for a wide range of applications, especially decontamination of organic pollutants. Bi, Pd, Pt, Ni, and Cd are other metal photocatalysts used for improved photocatalytic activities [357][358][359][360][361][362][363]. Some semiconductors are also used besides the metal oxide-g-C 3 N 4 based composites.…”

g-C3N4 has drawn lots of attention due to its photocatalytic activity, low-cost and facile synthesis, and interesting layered structure. However, to improve some of the properties of g-C3N4, such as photochemical stability, electrical band structure, and to decrease charge recombination rate, and towards effective light-harvesting, g-C3N4–metal oxide-based heterojunctions have been introduced. In this review, we initially discussed the preparation, modification, and physical properties of the g-C3N4 and then, we discussed the combination of g-C3N4 with various metal oxides such as TiO2, ZnO, FeO, Fe2O3, Fe3O4, WO3, SnO, SnO2, etc. We summarized some of their characteristic properties of these heterojunctions, their optical features, photocatalytic performance, and electrical band edge positions. This review covers recent advances, including applications in water splitting, CO2 reduction, and photodegradation of organic pollutants, sensors, bacterial disinfection, and supercapacitors. We show that metal oxides can improve the efficiency of the bare g-C3N4 to make the composites suitable for a wide range of applications. Finally, this review provides some perspectives, limitations, and challenges in investigation of g-C3N4–metal-oxide-based heterojunctions.

“…The type-II heterostructures were also explored because the separation and migration of e − /h + pairs were more appropriate at the electrode–electrolyte interface. The p–n heterojunction-based systems such as Bi 2 S 3 /CdS, 9 CeO 2 /3Dg-C 3 N 4 , 89 MXene/Bi 2 WO 6 , 95 ZnO/Co 3 O 4 , 139 CuO/ZnO, 92 NiO/g-C 3 N 4 , 91 BiFeO 3 /ZnO, 90 Bi 2 WO 6 /BiOI, 88 g-C 3 N 4 /Bi 9 O 7.5 S 6 140 and TiO 2 /ZnO 141 were reported for the photoreduction of CO 2 to valuable products (Table 2). Huang et al reported the Co 3 O 4 @CdIn 2 S 4 p–n junction catalyst for the reduction of CO 2 under visible light.…”
