“…The retained holes oxidized the absorbed BA to produce BAD. Additionally, various dual-functional photocatalyst, such as ZnS, Zn 3 In 2 S 6 , RuO x /TiO 2 , Pt/TiO 2 , Ni/Zn 0.5 Cd 0.5 S, Au/ZnIn 2 S 4 , Co/CdS, Ru/SrTiO 3 :Rh, NCN CN X -NiP, Ni/CdS, Co 9 S 8 /CdS were fabricated for coupling H 2 evolution with benzyl alcohol oxidation under light illumination. Recently, the merging of H 2 production and furfural alcohol oxidation was also achieved over the Ti 3 C 2 T x /CdS composite under the irradiation of visible light (λ > 420 nm) …”

Photocatalytic selective organic transformations provide an efficient synthetic alternative for several industrially relevant chemicals using solar rather than thermal energy. However, in most cases, photocatalytic organic reaction systems involve only reductive or oxidative pathways with the aid of sacrificial reagents as efficient electron acceptors or donors, thus limiting the economic added value. Recently, merging selective organic reductions and oxidations in a dual-functional photocatalytic reaction system has been put forward to tackle this limitation. In this coupled reaction system, both the photogenerated electrons and holes can be simultaneously utilized to generate value-added products, make the overall process more valuable from the economic perspective. In this review, the development of dualfunctional photocatalytic organic synthesis is systemically summarized. Particular emphasis is paid to merging selective organic oxidation and reduction reactions and coupling selective organic transformations with chemical fuel generation (e.g., H2, CO). Also, a personal perspective on future developments in this field is provided. Although still in its infancy, it is expected that this dual-functional technology offers opportunities to develop the next-generation selective organic transformation processes that meet the stringent economic, societal, and ecological expectations.

Selective Photocatalytic CC Coupling of Bioethanol into 2,3‐Butanediol over Pt‐Decorated Hydroxyl‐Group‐Tunable TiO₂ Photocatalysts

2,3‐Butanediol (2,3‐BD) was synthesized through TiO2‐photocatalytic CC coupling of bioethanol synchronously with the liberation of an energy H2 molecule in an anaerobic atmosphere. It was found that the selectivity of 2,3‐BD is controlled by the amount of .OH. The less the .OH, the higher the 2,3‐BD selectivity. Furthermore, it was revealed that the amount of .OH increases with the increasing of the surface OH groups on TiO2 photocatalyst. The introduction of water is in favor of the CC coupling pathway. This can be attributed to the stronger interaction between water and TiO2, which is beneficial to recovering the OH groups and promoting the desorption of .CH(OH)CH3 intermediates, thus suppressing the thermodynamically favorable overoxidation of .CH(OH)CH3 into acetaldehyde and promoting the CC coupling into 2,3‐BD. Based on the findings, the 2,3‐BD selectivity was greatly enhanced from approximately 2.6 % to approximately 65 % over Degussa P25‐TiO2 photocatalyst through fluorine substitution of surface OH groups.
