Herein, a photocatalytic system supported by a SrCoO-MoS (SCOS) heterojunction, which possessed a unique S-O electron transport channel, was proposed to facilitate HO production under condition where glycerol served as a sacrificial agent. The SCOS heterojunction achieved a remarkable yield of 15.90 mmol g h HO production, 3.7 times higher than the base component SCO. The construction of the heterojunction enriched the oxygen vacancies on the catalyst surface, facilitated photogenerated charge separation, and promoted the adsorption of O, reducing the oxygen reduction reaction (ORR) energy barrier. Besides, glycerol served as a unique proton donor, efficiently captured holes to enhance HO production, and generated valuable by-products including glyceric acid and dihydroxyacetone. Furthermore, SCOS exhibited excellent stability over repeated cycles with consistent HO yields. This study offers an efficient photocatalytic system and demonstrates glycerol’s potential in green oxidation processes.","PeriodicalId":516528,"journal":{"name":"Applied Catalysis B: Environment and Energy","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142249999","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

By engineering the primary facet from (101) to (112), the asymmetrical feather of MIL-101(Fe)(112) result in potential difference on varied facets to contribute to anisotropic charge migration, which has been determined by the preferentially photodeposited cocatalysts on facet (112) and facet (119) of the nanocrystal. Thus-observed anisotropic charge migration of MIL-101(Fe)(112) contribute to 10 times stronger internal electric field (IEF) to accelerate charge separation and migration. Also, we demonstrate the lowest unoccupied crystal orbital (LUCO) of MIL-101(Fe)(112) deepened (up to 3.33 eV vs. NHE) and acquire 3.5 times higher photogenerated holes for robust hole oxidation capacities. As a proof-of-concept, the optimal MIL-101(Fe)(112) can acquire 100 % higher degradation rate and 33 % higher mineralization than MIL-101(Fe)(101). This work highlights the importance of unsymmetric facet manipulation in tailoring photocatalysts for efficient photocatalytic oxidation.","PeriodicalId":516528,"journal":{"name":"Applied Catalysis B: Environment and Energy","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205081","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we present Fe-doped nickel hydrogen cyanamide (NiFe-HC), which is rapidly surface reconstructed into NiFe(OOH)-HC after OER. In-situ Raman spectroscopy and density functional theory (DFT) calculations, revealed that under OER conditions, -HNCN- converts into -NCN- ligand incorporating its abundant and uniform distribution across the active sites. DFT calculations further indicate that Fe predominantly acts as the active site, with -NCN- ligands contribute to the OER by facilitating the deprotonation of *OH in the rate-determining step (RDS), acting effectively as proton acceptor. The ensemble effect between Fe and -NCN- ligand forms the foundation of the exceptional electrocatalytic performance of NiFe(OOH)-HC (190 mV at 20 mA·cm).

Furthermore, even after 6 hours of tannic solution filtration, the membrane maintains a high flux of 517 L m h bar. Combined with various spectral and photoelectric performance tests confirmed that AE/Cu-FeOOH-PVDF possesses high separation and transfer efficiency of photogenerated carriers. Meanwhile DFT calculation showed that the composite has better adsorption properties and HO activation ability. AE provided e to Cu-FeOOH, which accelerated the redox reaction process of Fe and Cu ions and produced more stable active free radicals to degrade tannic.

In this study, a fresh perspective has emerged proposing to synergistically enhance the adaptability and resilience of dynamic torsion patterns in π-conjugated polymers to mediate charge separation and molecular activation. Excitingly, the highest flexible-robust structure and polarity of naphthalene-linked perylene diimide polymer (N-PDA) demonstrates a highest nitrate reduction rate of 5.36 mmol g h under light irradiation and ultrasonic condition, which is 7.5 times that of H-PDA. Theoretical calculations and experimental observations indicate that the strongest flexible-robust structure of N-PDA enhances the inclination of the rigid plane and atomic bond length, resulting in an accelerated uneven distribution of charges, molecular polarity, and electronic coupling to facilitate charge separation dynamics. Moreover, it exposes active sites that promote the adsorption and activation of NO ions while simultaneously regulating intermediate hydrogenation processes. Our study offers innovative prospects for enhancing catalytic efficiency through the implementation of spatial steric configuration of π-conjugated polymers.","PeriodicalId":516528,"journal":{"name":"Applied Catalysis B: Environment and Energy","volume":"29 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205086","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
