The chemistry of nitrogen and phosphorus is very important in the field of catalysis. Three types of nitride containing NiMo/γ-Al<sub>2</sub>O<sub>3</sub> catalysts were synthesized using different loading-nitriding sequences and oxide precursor types for dry reforming of methane (DRM). The active components (Ni<sub>2</sub>Mo<sub>3</sub>N and Ni/Mo<sub>2</sub>N) firstly reacted with CO<sub>2</sub>, transforming into NiO and MoO<sub>2</sub>. They were then carburized with CH<sub>4</sub> to produce Ni/Mo<sub>2</sub>C during the DRM process. From that point on, a redox cycle, viz. NiO/MoO<sub>2</sub> ⇆ Ni/Mo<sub>2</sub>C, occurred during the DRM reaction. The low activity of nitriding-first NiMo nitride catalyst can be attributed to bulk oxidation. The observed gradual decline in performance of loading-first Ni/Mo nitride catalyst was due to coking. Noticeably, the loading-first NiMo nitride catalyst can demonstrate superiority in both activity and resistance to coking, which was due to its strong metal–Al<sub>2</sub>O<sub>3</sub> interaction and high metal dispersion.</div></div>","PeriodicalId":20056,"journal":{"name":"Phosphorus, Sulfur, and Silicon and the Related Elements","volume":"200 1","pages":"Pages 46-53"},"PeriodicalIF":1.4,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143350032","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 findings revealed that the key determinants of pyridine adsorption onto vulcanized oil shale included the pH level of the pyridine solution, contact time, initial pyridine concentration, and the quantity of vulcanized oil shale introduced into the system. Under optimal adsorption conditions, the vulcanized oil shale achieved a 48.00% adsorption efficiency and an equilibrium adsorption capacity of 4.83 mg·g<sup>−1</sup>. In contrast, the untreated oil shale exhibited a comparatively reduced adsorption efficiency of 22.88% under its respective optimal conditions. The research further examined the adsorption kinetics and isothermal adsorption models for both types of oil shale. The kinetic data indicated that pyridine adsorption followed a pseudo-second-order model. The pyridine adsorption isotherms for both oil shale and vulcanized oil shale were best described by the Freundlich model, compared to the Langmuir model. These findings provide significant insights into the utilization of vulcanized oil shale for the efficient treatment of low-concentration pyridine wastewater, potentially contributing to environmental remediation and pollution control strategies.</div></div>","PeriodicalId":20056,"journal":{"name":"Phosphorus, Sulfur, and Silicon and the Related Elements","volume":"200 1","pages":"Pages 90-100"},"PeriodicalIF":1.4,"publicationDate":"2025-01-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143360823","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}
