Abstract Achieving synergistic oxidation and reduction represents a significant challenge in the field of photocatalysis. In this study, hydrothermal/in situ construction Bi atom clusters within 2 Sn O 7 /ZnIn S 4 (BSO/ZIS) heterostructures is reported. These exhibit self‐accelerating charge‐transfer mechanisms facilitated by internal electric fields bonding bridges, resulting highly efficient light absorption capabilities. X‐ray photoelectron spectroscopy (XPS) Kelvin probe force microscopy (KPFM), as well theoretical calculations, indicate that canonical induction promotion electrons holes lowers activation energy CHO* generation, allowing simultaneous CO toluene over catalyst, enhances proton‐coupling electron‐transfer processes, unique reaction mechanism. The reactant, Bi‐Bi (B‐BSO/ZIS) heterostructure achieves rate to 726.3 µmol g −1 h (99.9% selectivity) benzaldehyde 2362.0 (98.0% selectivity), which increases activity 14.6 5.7 times compared pristine ZnIn . This study underscores significance modulating photocatalytic pathway through strategic selection metal reactants, contributing rational design photocatalysts for enhanced adsorption stabilization *H.

The excessive emission of carbon dioxide (CO2) into the atmosphere has led to a significant global warming crisis. Utilizing bifunctional catalysts, which consist bimetallic oxides and SAPO-34, for catalyzing conversion CO2 high-value-added ethylene (C2H4) can effectively mitigate this issue. However, process also produces substantial number by-products. Additionally, use bimetallics or precious metals increases catalyst costs. In study, we propose an innovative synergistic approach by integrating SAPO-34 with TiO2, enabling both efficient capture its catalytic C2 hydrocarbons. system achieved C2H4 yield 20 μmol g-1 selectivity 63.5%. Comprehensive characterizations revealed that 30% TiO2/SAPO composite exhibited higher concentration oxygen vacancies greater percentage Ti3+ species. Moreover, confinement effect facilitated C-C coupling formation C2H4. This work exemplifies dual-functional strategy, providing valuable insights reduction.

Enhanced Photocatalytic CO2 Reduction with Incorporation of WO3 Cocatalyst in g-C3N4-TiO2 Heterojunction

Molecules, Год журнала: 2025, Номер 30(11), С. 2317 - 2317

To enhance the performance of photocatalytic CO2 reduction, development suitable cocatalysts represents an effective strategy. Cocatalysts can interact with photocatalysts to improve light absorption capabilities and facilitate separation transfer photogenerated electrons holes. Moreover, they provide highly active surface sites that promote adsorption activation CO2, which leads acceleration reduction. Herein, WO3 is employed as a cocatalyst photoreduction g-C3N4-TiO2 heterojunction through facile scalable calcination method. In pure water, optimal WO3/g-C3N4-TiO2 (WCT) delivers high selectivity CO CH4 formation 48.31 µmol·g−1 77.18 in absence sacrificial reagent extra photosensitizer, roughly 13.9 45.7 times higher than (CT). strongly electronically, guiding across interface surface. The oxygen vacancies WO3, electron-enriched centers, not only charge form efficient channels but also capture suppress recombination. This strong interaction jointly reduction activity selectivity, offering feasible way design cocatalysts.
