The introduction of oxygen vacancies improved electron-hole separation efficiency, thereby enabling efficient water-splitting. X-ray photoelectron spectroscopy (XPS) analysis revealed that WO<sub>3</sub>/H-BiVO<sub>4</sub> exhibited a lower reflectance infrared (RIR) value, signifying a higher concentration of surface oxygen vacancies compared to WO<sub>3</sub>/BiVO<sub>4</sub>. Photoelectrochemical measurements at 1.23 V vs. RHE demonstrated that WO<sub>3</sub>/BiVO<sub>4</sub> achieved photocurrent densities and carrier densities 5-fold and 1.3-fold greater, respectively, than WO<sub>3</sub>. Notably, WO<sub>3</sub>/H-BiVO<sub>4</sub> exhibited further enhancements, with photocurrent densities and carrier densities 1.4-fold and 2.4-fold higher, respectively, than WO<sub>3</sub>/BiVO<sub>4</sub>. These findings underscore the critical role of heterojunction construction in boosting photocatalytic activity, while oxygen vacancy introduction further elevates photoelectric performance. Specifically, WO<sub>3</sub>/H-BiVO<sub>4</sub> achieved a peak photocurrent density of 6.5 mA·cm<sup>− 2</sup> at 1.6 V vs. RHE, attributed to its superior photogenerated charge separation and surface charge transfer efficiency. This study highlights that rationally expanding interfacial contact and optimizing oxygen vacancy concentrations are effective strategies for enhancing photocatalytic performance. These insights provide a valuable framework for the design and development of highly efficient photocatalysts for water-splitting applications.</p><h3>Graphical Abstract</h3><div><figure><div><div><picture><source><img></source></picture></div></div></figure></div></div>","PeriodicalId":508,"journal":{"name":"Catalysis Letters","volume":"155 4","pages":""},"PeriodicalIF":2.3,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489527","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The characterization of these catalysts is carried out using a range of analytical techniques, including measurements of surface area and porosity, thermogravimetric analysis (TGA), X-ray diffraction (XRD), transmission electron microscopy (TEM), hydrogen temperature-programmed reduction (H<sub>2</sub>-TPR), temperature-programmed oxidation (TPO) and desorption (TPD) studies. The concentration of active sites, as well as the presence of acid and basic sites on the catalyst surface, are the primary factors influencing the catalytic activity of the 5Ni + xSr-MgO catalysts (where x = 1, 2, 3, and 4 wt%). Ni, supported over MgO, has few active sites and lacks a strong basic site, which results in minimum catalytic activity. Adding 1–4 wt% Sr over 5Ni-MgO induces the formation of higher concentrations of active sites and an increased population of strong basic sites. At 3 wt% Sr loading, concentration of active sits, strong basic sites, and strong acid sites are optimum which can activate CH<sub>4</sub> and CO<sub>2</sub> timely for DRM rather than coke deposition. So, 5Ni + 3Sr-MgO achieved 58.4% CH<sub>4</sub> conversion (with H<sub>2</sub>/CO ratio 1.1) at 700 <sup>°</sup>C and ~ 82% CH<sub>4</sub> conversion at 750 <sup>°</sup>C.
