Unveil the Potential of MOF-based Single-Atom Photocatalyst for Production of Clean Fuel and Valuable Chemical

Chemical Communications, Год журнала: 2024, Номер unknown

Опубликована: Янв. 1, 2024

Harnessing solar energy through photocatalysis has excellent potential for powering sustainable chemical production, supporting the United Nations' environmental goals. Single-atoms (SAs) dispersed on catalyst surfaces are gaining attention their highly active and durable nature. Metal-organic frameworks (MOFs) can provide enough reactive sites to sustain selectivity durability over time because of tunable channels functional groups. Owing organized structures, MOFs ideal platforms securing individual atoms promoting solar-driven reactions. Few reviews have, however, reflected possibility combining SAs produce potent photocatalysts that may clean fuels valuable chemicals. This review provides a general overview methods generate photocatalysts. The challenges associated with these MOF-based single-atom systems also critically examined. Their future development is discussed as continued refinement helps more fully leverage advantages boosting photocatalytic performances - turning sunlight into chemicals in manner supports development. Insights gained here could illuminate pathways toward realizing profound empower production driven by renewable energy.

Multifunctional diamond‐based catalysts: Promising candidates for energy conversions in extreme environments—A mini‐review

Electron, Год журнала: 2024, Номер 2(3)

Опубликована: Июль 1, 2024

Abstract In order to properly utilize the abundant CO 2 and water resources, various catalytic materials have been developed convert them into valuable chemicals as renewable fuels electrochemically or photochemically. Currently, most studies are conducted under mild laboratory conditions, but for some extreme environments, such Mars space stations, there is an urgent need develop new catalysts satisfying special requirements. Conventional mainly focus on metals narrow bandgap semiconductor materials, while research wide ultrawide that can inherently withstand conditions has not received enough attention. Given robust stability excellent physico‐chemical properties of diamond, it be expected perform in harsh environments electrocatalysis photocatalysis investigated thoroughly. Here, this review summarizes functionality diamond‐based electrodes with tunable product selectivity obtain varied C 1 2+ products, discusses important factors playing a key role manipulating activity. Moreover, unique solvation electron effect diamond gives significant advantage photocatalytic conversions which also summarized mini‐review. end, prospects made application conditions. The challenges may faced practical applications future breakthrough directions proposed at end.

Modulating e_g Occupancy by A‐Site Vacancy to Boost Photocatalytic CO₂ Reduction on Perovskite Oxides

Advanced Functional Materials, Год журнала: 2025, Номер unknown

Опубликована: Янв. 16, 2025

Abstract For photocatalytic CO 2 reduction, traditional ABO 3 perovskite oxides have suffered from the natural surface covered by passivated AO layer, resulting in low activity. Herein, double Sr TiFeO 6 is used as a precursor and citric acid employed to selectively dissolve A‐site cation, obtaining v ‐Sr with abundant vacancies. Without using any co‐catalysts or sacrificial agents, achieves efficient photoreduction of CH 4 91% selectivity 43.17 µmol g −1 h yield, which almost five times that original . The results indicate removing can increase concentration oxygen vacancies significantly reduce exciton binding energy 0.61 0.32 eV, thereby enhancing charge transfer efficiency. Furthermore, adjust electronic structure, leading decrease e electrons occupancy on active B‐site. This shift reaction intermediates strong adsorption moderate adsorption. Specifically, barrier water oxidation reaction, rate‐determining step for overall greatly reduced. work provides vivid case modulating structure oxide through introducing defects
