Energy level mismatches between semiconductors and cocatalysts often induce carrier recombination, limiting photocatalytic photoelectrochemical (PEC) efficiency. Here, we integrate Pt nanocluster-Fe single-atom pairs with CuO to regulate both solid-solid solid-liquid interfaces in PEC systems. Experimental theoretical analyses reveal that an Ohmic contact at the CuO/Pt interface accelerates electron extraction, while Pt-to-Fe charge transfer enhances oxygen reduction Fe sites, collectively boosting reaction kinetics. Leveraging this, construct a biosensor exploiting chelating effect of glyphosate on impede transfer, achieving detection limit 0.41 ng/mL. This engineering strategy advances cocatalyst design for enhanced energy conversion sensing applications by simultaneously addressing dynamics interfacial barriers. Efficient extraction photoelectrocatalysts requires matching levels catalysts. authors show this from copper oxide combining platinum nanoclusters iron

Natural photosynthesis (NP) generates oxygen and carbohydrates from water CO2 utilizing solar energy to nourish lives balance levels. Following nature, artificial (AP), typically, overall or splitting, produces fuels chemicals renewable energy.
