Herein, we developed an effective topotactic transition synthesis route of producing few deep-level defects porous Ta3N5 film from the precursor film of ammonium tantalum oxyfluoride compound ((NH4)2Ta2O3F6) pyramids on the Ta foil. The highly electronegative fluoride ions in (NH4)2Ta2O3F6 could weaken the Ta–O bonds and the accompanied porous structure facilitates reactant diffusion, which favors the complete nitridation. Consequently, the resulting porous Ta3N5 film has very few deep-level defects, enabling an ultralow photocurrent onset potential at 0.2 V (vs. RHE) and a short-circuit photocurrent density (Jsc) of 3.28 mA cm−2 after decorating oxygen evolution reaction (OER) cocatalysts under AM 1.5 G irradiation. Moreover, the Jsc can retain 85% of the initial value for a 5 h continuous stability test. By reducing the particle size of (NH4)2Ta2O3F6 pyramid precursor, the deep-level defects could be further lowered in the Ta3N5 film, achieving the photoactivity for water oxidation at 0 V (vs. RHE) after modifying the OER co-catalyst.</div>","PeriodicalId":9832,"journal":{"name":"Chinese Journal of Catalysis","volume":"61 ","pages":"Pages 144-153"},"PeriodicalIF":15.7,"publicationDate":"2024-06-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141607516","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, the structural properties, the acid sites, and the existence status of the Zn species in the Zn-introduced catalysts were systematically characterized by several techniques. And the influence of the state of Zn species in the coupling reaction was discussed. The results indicate that the Zn species exist in the form of ZnO cluster, Zn-OH+, and (Zn-O-Zn)2+ species, thereinto (Zn-O-Zn)2+ species are produced by the Zn-OH+ group with the increasing Zn loading. The decrease of Brønsted acid sites, the formation of newly active sites caused by Zn species, and the accumulation of coarse ZnO species, are responsible for the change of n-butane conversion.
