Abstract The photocatalytic reduction of CO 2 in water to produce fuels and chemicals is promising while challenging. However, many photocatalysts for accomplishing such challenging task usually suffer from unspecific catalytic active sites the inefficient charge carrier's separation. Here, a site‐specific single‐atom Ni/TiO 2−x catalyst reported by situ topological transformation Ni‐Ti‐EG bimetallic metal–organic frameworks. loading nickel nanoparticles or individual atoms, which act as specific sites, can be precisely regulated chelating agents through partial removal adjacent oxygen atoms. Furthermore, degree lattice strain catalysts, improves separation efficiency carriers, modulated fine‐tuning process. By leveraging anchored atoms strained TiO , optimized Ni SA0.27 /TiO shows generation rate 86.3 µmol g −1 h (288 times higher than that NPs ) selectivity up 92.5% pure‐water system. This work underscores importance tailoring creating facilitate efficient selective .

Given its multifaceted important roles such as aqueous oxidant, chemical platform for environmental remediation, possible liquid fuel, and so on, environmentally friendly approaches to produce hydrogen peroxide (H2O2) are highly desirable. In this context, the photocatalytic generation of from water oxidation has emerged a promising method, phenol–formaldehyde-based functional resins have been established an excellent developing photocatalysts oxidation. The present work reports development resorcinol–formaldehyde (RF) TiO2 (RF/TiO2) composites efficient heterogeneous production H2O2 through synthesis RF/TiO2 was accomplished following simple high-temperature hydrothermal it characterized study microstructures optical properties. role optimum amount in improving activity resin by with varied amounts TiO2. As experimentally established, prepared 1.1–1.6% (w/w) feed respect resorcinol at temperature 200 °C under conditions were found be most ones study. Out these composites, RF/TiO2-1.2% RF/TiO2-1.3% resulted ∼500 ∼530 μmol per gram catalyst, respectively, upon 5 h continuous photoirradiation experimental reaction ∼30–35 °C. It observed that rate can enhanced increasing temperature.
