Cocatalysts for Selective Photoreduction of CO2into Solar Fuels

“…This work highlights that the rational design and control of novel nano/micro structures could effectively increase their surface area and porosity, resulting in an enhanced CO 2 photoreduction and adsorption. Besides Bi 2 WO 6 hollow microspheres, various kinds of other hierarchical photocatalysts have been fabricated by different strategies and widely applied in the photocatalytic CO 2 reduction, such as ordered macro/mesoporous TiO 2 sponges or microspheres, − TiO 2 photonic crystals (slow photon effect), , TiO 2 nanorod array@carbon cloth, Ti 0.9 O 2 –graphene hollow spheres, TiO 2 –graphene architectures, , CdIn 2 S 4 microspheres, Mn 0.8 Cd 0.2 S microspheres, Zn 1.7 GeN 1.8 O hyperbranched nanostructures, porous TaON microspheres, BiOBr microspheres, cadmium–aluminum LDH microspheres, NaTaO 3 hierarchical porous structure, Bi-rich Bi 4 O 5 Br x I 2– x microspheres, tree trunk derived tantalates MTaO 3 (M = Li, Na, K), 3D ordered mesoporous Fe-doped CeO 2 and TiO 2 /CeO 2 , , CdS@CeO 2 core/shell microspheres, CeO 2 /Bi 2 MoO 6 heterostructures, Bi 2 S 3 /CeO 2 superstructure, foam-like Cu 2 O structure, flower-like CdS/CdV 2 O 6 , flower-like Zn x Ca 1– x In 2 S 4 , TiO 2 nanofibers, irregular CoTe nanoflakes, flower-like Bi 2 WO 6 , ,, Bi 2 S 3 urchin-like microspheres, CuO–TiO 2 hollow microspheres, ZnV 2 O 6 nanosheets, double-shelled ZnGa 2 O 4 hollow spheres, ZnO/NiO porous hollow spheres, LaPO 4 hierarchical hollow spheres, β-SiC hollow spheres, zinc germanium oxynitride hyperbranched nanostructures, graphene–g-C 3 N 4 sandwich-like nanostructures, porous O-doped graphitic carbon nitride (g-C 3 N 4 ) nanotubes, sandwich-like ZnIn 2 S 4 –In 2 O 3 hierarchical tubular heterostructures, In 2 S 3 –CdIn 2 S 4 heterostructured nanotubes, 3D ZnIn 2 S 4 nanosheets/TiO 2 nanobelts, N-doped carbon@NiCO 2 O 4 double-shelled nanoboxes, flower-like Bi 2 MoO 6 microspheres, alkaline tantalates MTaO 3 (M = Li, Na, K), ATiO 3 (A=Sr, Ca, Pb), SrTiO 3 leaf’s 3D architecture, ZnGa 2 O 4...…”

Superior performance of FeVO4@CeO2 uniform core-shell nanostructures in heterogeneous Fenton-sonophotocatalytic degradation of 4-nitrophenol

“…Moreover, the reactions of all catalysts occur at the same time and the strength of the shell can protect the core and prevent assemblage of the particles [15,16]. In this context, many researchers have used various core shell nanostructures [17][18][19][20][21][22][23][24][25][26][27][28][29][30][31]. Among the inorganic shell materials, cerium oxide (CeO2) has served as one of the most efficient photocatalysts for the degradation of organic pollutants because of its ability to transform between Ce +3 and Ce +4 states at oxygen vacancy sites, and to facilitate electron transfer and e -/h + pair di usion between CeO2 and another semiconductor such as Cu2O [32], CdS [33] and TiO2 [34,35].…”

Recent Innovation of Metal-Organic Frameworks for Carbon Dioxide Photocatalytic Reduction

“…The photocatalytic reduction performance of this material exhibits 99% CO selective reduction of CO 2 ; this hybrid membrane's MOF activity is exceptional compared to other ever reported research findings [153,[274][275][276][277][278][279][280][281][282]. In addition, the incorporation of another semiconductor to the hybrid membrane increases photocatalytic photoinduced redox reaction by the prevalent facile exciton transfer with prohibited charge recombination, which is due to the provision of synergistic reaction between the MOF and semiconductor [137,283].…”
