An etching and re-growth method for the synthesis of bismuth ferrite/MIL-53(Fe) nanocomposite as efficient photocatalyst for selective oxidation of aromatic alcohols

Metal–Organic Frameworks (MOFs) and Covalent Organic Frameworks (COFs) Applied to Photocatalytic Organic Transformations

“…Most of them are devoted to their use as photocatalysts in the selective oxidation of benzylic alcohol and other oxidation processes (see in more detail below). Apart from MOF-NPs, other hybrid materials have been obtained in this field by using CdS quantum dots [80], bismuth ferrite [81], graphene oxide [82], fullerene C 60 [83], and polyoxometalates [48] as composite partners.…”

“…This hybrid material achieved the corresponding oxidized products after 3 h in moderate conversions [93]. Very recently, a very active photocatalytic material has been reported by Yin [81]. The etching and regrowth process on a 3D MIL-53(Fe), that generates bismuth ferrite (BFO) nanosheets on its surface, was used as a strategy in order to avoid fast electron-hole recombination.…”

Solvent Effects on Photocatalytic Anaerobic Oxidation of Benzyl Alcohol over Pt-Loaded Defective SrTiO3 Nanoparticles

“…Efficient utilization of solar energy for the production of high value-added fine chemicals via artificial photosynthesis on various heterogeneous photocatalysis processes is a promising green pathway to solve the urgent worldwide energy crisis. − Typically, anaerobic photocatalytic selective oxidation of alcohols to corresponding carbonyl compounds is a fundamental and significant reaction in photosynthesis, releasing molecular hydrogen as the sole byproduct. − To date, much effort has been made for selective oxidation of alcohols in organic solvents (e.g., acetonitrile (ACN), benzotrifluoride, methyl chloride, and ethyl acetate) with various photocatalysts. For instance, Ni-decorated Zn 0.5 Cd 0.5 S, Ni-modified CdS nanoparticles (NPs), and Ag 2 S-CdS p–n nanojunction have been used to efficiently split alcohols into hydrogen and the corresponding aldehydes or ketones in a stoichiometric manner with acetonitrile as the solvent under visible light. ,,, C 3 N 4 photocatalysts decorated with Pt nanoparticles have been utilized for photocatalytic dehydrogenation of alcohols in acetonitrile and showed 72% conversion of benzhydrol and 98% selectivity of the product diphenyl ketone .…”

Highly efficient heterogeneous photo-Fenton BiOCl/MIL-100(Fe) nanoscaled hybrid catalysts prepared by green one-step coprecipitation for degradation of organic contaminants

“…Compared with pure MOFs, MOF-based heterostructure materials have been found to show lower electron–hole recombination rates and higher visible-light adsorption regions. 24 Heterostructure materials such as Fe-based MOFs/g-C 3 N 4 , 25 MIL-88A(Fe)/GO composites, 26 needle-shaped 1T-MoS 2 @MIL-53(Fe) composites, 27 bismuth ferrite/MIL-53(Fe) nanocomposite, 28 and CUCs-MIL-88B(Fe)/Ti 3 C 2 (ref. 29 ) have been found to show enhanced photocatalytic activity because of the formation of a compact and uniform interfacial contact between the MOFs and other semiconductors; the interfacial contact accelerates the separation of the photoinduced charges and decreases the electron–hole recombination rate.…”
