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}

Upon introducing 4-methoxythiophenol (MTP), the fluorescence intensity of NI-TPA-1 exhibited a remarkable 18-fold increase, achieving detection limits as low as 20 nM in aqueous solutions. The photo-induced electron transfer (PET) response mechanism was elucidated through density functional theory (DFT) calculations, providing valuable insights into the sensing mechanism of the probe. Furthermore, the practical applicability of NI-TPA-1 was demonstrated through its successful detection of thiophenol in real water samples.
