M/BiOCl-(M = Pt, Pd, and Au) Boosted Selective Photocatalytic CO Reduction to C Hydrocarbons via *CHO Intermediate Manipulation.

Selective CO photoreduction to C hydrocarbons is significant but limited by the inadequate adsorption strength of the reaction intermediates and low efficiency of proton transfer. Herein, an ameliorative *CO adsorption and HO activation strategy is realized via decorating bismuth oxychloride (BiOCl) nanostructures with different metal (Pt, Pd, and Au) species. Experimental and theoretical calculation results reveal that distinct *CO binding energies and *H acquisition abilities of the metal cocatalysts mediate the CO reduction activity and hydrocarbon selectivity.

Interfacial complexation between Fe and BiMoO promote efficient persulfate activation via Fe/Fe cycle for organic contaminates degradation upon visible light irradiation.

To address the observed decrease in efficiency during Fe-mediated persulfate (PDS) activation caused by slow electron transfer rates and challenges in cycling between Fe/Fe states, we devised a strategy to establish interfacial complexation between Fe and BiMoO in the presence of PDS. The proposed approach facilitates more efficient capture of photogenerated electrons, thereby accelerating the rate-limiting reduction process of the Fe/Fe cycle under visible light irradiation and promoting PDS activation. The BiMoO/Fe/PDS/Vis system demonstrates complete degradation of organic pollutants, including Atrazine (ATZ), carbamazepine (CBZ), bisphenol A (BPA), and 2,4-dichlorophenol (DCP) at a concentration of 10 mg/L within a rapid reaction time of 30 min.
