Inorganic-organic hybrid photocatalysts: Syntheses, mechanisms, and applications

Targeted H2O activation to manipulate the selective photocatalytic reduction of CO2to CH3OH over carbon nitride-supported cobalt sulfide

“…S15†), which is also often formed in the process of H 2 O activation. 21,23,59,60 In contrast, CN showed strong signals of ˙OH and ˙O 2 − , which may have been caused by the formation of holes (valence band: 2.07 eV) with strong oxidation capacity in CN (Fig. 4e and f).…”

Constructing Exfoliated, Ti3C2Tx MXene-Dispersed, LaCoO3 and pC3N4-Based Nanocomposites with In Situ Grown Titania through Etching/Oxidation for Stimulating Solar H2 Production

“…For instance, TiO 2 is considered a stable and cost-effective semiconductor with a good oxidation potential, but it faces issues of wide band gaps, charge recombination, and slow kinetics of the reaction, leading to lower overall efficiency . Therefore, less costly, environmentally safe, highly stable, and efficient photocatalysts for expanding H 2 generation and CO 2 reduction on a large scale are urgently demanded …”

2D MoS2/BiOBr van der Waals heterojunctions by liquid-phase exfoliation as photoelectrocatalysts for hydrogen evolution

“…In this combined method, the energy conversion efficiency is supposed to be higher than that of single photocatalysis and electrocatalysis. 1 A variety of inorganic oxides and chalcogenides have been applied as photoelectrocatalysts in the hydrogen evolution reaction, such as Cu 2 O, 2 BiVO 4 , 3 Fe 2 O 3 , 4 Sb 2 Se 3 , 5 MoS 2 , 6 CdS 7 and many others. However, the efficiency and stability of the catalysts in these PEC systems still remain open issues.…”
