As global CO2 emissions continue to rise, addressing their environmental impact is critical in combating climate change. Photocatalytic reduction, which mimics natural photosynthesis by converting into valuable fuels and chemicals using solar energy, represents a promising approach for both reducing storing energy sustainably. However, the development of efficient photocatalysts, particularly those capable absorbing visible light, remains challenge. Graphitic carbon nitride (g-C3N4) has gained attention its light absorption chemical stability, though performance hindered rapid electron–hole recombination. Similarly, bismuth tungstate (Bi2WO6) visible-light-active photocatalyst with properties, but also suffers from limited efficiency due charge To overcome these limitations, this study focuses on design synthesis g-C3N4/Bi2WO6 composite photocatalyst, leveraging complementary properties materials. The benefits enhanced separation through formation heterojunction, recombination rates improving overall photocatalytic performance. optimized exhibited significant improvements production CH4 CO, achieving 18.90 17.78 μmol/g/h, respectively, are 2.6 times 1.6 higher than pure Bi2WO6. explores how optimizing interface, increasing surface area, adjusting material ratios can further enhance reduction. Our findings demonstrate potential solar-driven conversion, offering new insights paving way future advancements mitigation technologies.

The Direct Air Synthesis of Hydrogen Peroxide Induced by The Giant Built‐In Electric Field of Trz‐CN

Small Methods, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 14, 2025

Graphitic carbon nitride (C3N4) has been identified as an optimal material for hydrogen peroxide (H2O2) photosynthesis, although its utility is hampered by a high photocarrier recombination rate. Herein, novel with giant built-in electric field (BEF), Trz-CN, synthesized through hydrothermal-calcination tandem strategy. The BEF (4.8-fold) induced the large dipole moment facilitated efficient separation and directional migration of photogenerated carriers. Trz-CN exhibited H2O2 production rate 569.9 µmol·g-1·h-1 using O2 feedstock under visible light (λ > 420 nm), marking impressive 11.2-fold enhancement compared to bulk C3N4. Utilizing air instead pure resulted in trivial 1.6% decrease generation while maintaining substantial 560.6 µmol·g-1·h-1. Notably, showcased sterilization 99.9% against Escherichia coli (E. coli) natural seawater. Density functional theory (DFT) calculations revealed that incorporating nitrogen-rich skeleton into C3N4 enhanced oxygen adsorption capacity lowered energy barrier formation. This leads photocatalytic performance ambient conditions. provides new exploratory idea direct synthesis ballast water treatment.

Interfacial electron transfer between an inorganic semiconductor and a metal–organic framework (MOF) is the key to photocatalysis in composite photocatalytic system. The construction of structural defects single or MOF has been regarded as effective method for enhancing its performance. However, how microenvironment modulation sites defective semiconductors MOFs (quasi-MOFs) affects disinfection activity worth studying. Herein, integration their crystal defect achieved by directly dropping ZIF-8 suspension onto bismuth vanadate (BiVO4) nanoarray subsequently activating it through low-temperature (300 °C) calcination under N2 atmosphere. Compared with original BiVO4 nanoarray, (BiVO4-N2), BiVO4-ZIF-8 (BiVO4-ZIF-8)-N2 exhibits enhanced (6.63 log10 CFU mL–1 after 4 h simulated sunlight irradiation) due improved sluggish kinetics transfer. In situ irradiated operando near-ambient pressure XPS (NAP-XPS) confirms interfacial transfer, which can greatly modulate site thus lead efficient photocatalysis.
