Emerging Single-Atom Catalysts and Nanomaterials for Photoelectrochemical Reduction of Carbon Dioxide to Value-Added Products: A Review of the Current State-of-the-Art and Future Perspectives

“…The hybrid photocatalytic composite employing 4% weight Cu 2 O NPs (a p-type semiconductor) combined with Mo 2 C/TiO 2 and incorporated in an optofluidic microreactor resulted in 36.3 μmol g –1 h –1 CH 3 OH formation . Hao et al incorporated an S-scheme heterojunction by synthesizing a CdS/Bi 2 WO 6 hybrid composite, which showed augmented PC operation, resulting in the evolution of 54.9 μmol g –1 and 4.8 μmol g –1 of CO and CH 4 , respectively . Employing double perovskite nanomaterial (NMT) such as Cs 2 AgBiBr 6 encapsulated with TiO 2 to fabricate the TiO 2 /Cs 2 AgBiBr 6 hybrid composite revealed excellent PC activity resulting in the formation of CO and CH 4 amounting to 5.72 μmol g –1 h –1 and 8.46 μmol g –1 h –1 , respectively .…”
