“…The amorphous carbon in C/ZnO nanofibers enhances light absorption and reduces the interface resistance of charge transport. 47 The current work provides an alternative approach to the use of non-precious metal cocatalysts to boost the CO 2 reduction activity of ZnO photocatalysts. C/ZnO nanofibers were prepared by electrospinning.…”

“…Carbon materials have many excellent physical and chemical properties, and are widely used in many fields [38,39,40,41,42]. The advantages of graphene-based photocatalysts lie in the unique properties of graphene, such as high electron conductivity and excellent charge mobility, which lead to longer lives of photo-generated electrons and holes pairs produced by semiconductor nanoparticles on graphene sheets, and thus higher photocatalytic efficiency [43,44,45]. However, the high specific surface area of monodisperse graphene is decreased by the aggregation of two-dimensional graphene due to the strong attraction between the layers.…”

Bismuth ferrite (BiFeO3, BFO) submicron cubes and 3D BFO/graphene composite materials were synthesized by a simple hydrothermal process. The crystallization processes of the 3D BFO/graphene composites with different graphene oxide (GO) concentrations were studied for their visible light photocatalytic properties. Compared to the single BFO submicron cubes, 3D BFO/graphene composites have greatly improved photocatalytic activity. A high photocatalytic performance is obtained at a GO concentration of 3 mg/mL, with the degradation rate of methylene blue (MB) dye reaching up to 92% in 140 min. The enhancement of photocatalytic activity can be attributed to the large specific surface area and 3D architecture of 3D composites, which provide more transport paths to effectively improve the separation rate of photo-generated electrons and holes. Therefore, 3D BFO/graphene composites have a broad prospect of application in the field of photocatalysis.

Photocatalysis of carbon dioxide by the assistance of solar energy has been one of the most promising approaches to reduce CO 2 to renewable fuel. Several methods are pertained to enhance the photocatalytic activity for stimulating CO 2 reduction to selective fuels. Even though many researchers have been exploring methods of assembling a suitable semiconductor, practical constraints such as charge carrier recombination and low light utilization limit the photocatalytic activity. In this review, recent advancement in semiconductors and their characteristics toward the photoreduction of CO 2 has been comprehensively discussed. The major semiconductors that are discussed and analyzed based on their limitations in this review are TiO 2 , BiVO 4 , CdS, g-C 3 N 4 , ZnO, and MoS 2 -based composites. Initially, the fundamentals of heterogeneous photocatalysis such as the possible molecular pathways, product selectivity, and thermodynamics have been deliberated. Advancement in semiconductors in relation to quantum dots, heterojunction, and sacrificial reagent has been systematically analyzed. Doping and co-doping of semiconductors have proven to reduce the band gap notably and its outstanding electronic band position for the visible light photocatalysis has been identified. Furthermore, the developments of cocatalysts such as noble metals and nonmetals to stimulate photocatalysts performance in view of CO 2 reduction to value-added products have been disclosed. Specific developments in binary semiconductors through Z-scheme, S-scheme, and ternary heterojunction for charge separation and their characterization has been thoroughly deliberated. In addition, the role of doping, structural defects, as well as sensitization in enhancing the light harvesting abilities of the photocatalyst has been discoursed. The developments in photocatalytic reactors with their characteristics and limitations are also assiduously discussed. Finally, conclusions and future directions for photocatalysis of carbon dioxide toward renewable fuel production have been suggested.
