In this study, a series of Cu-SAPO-34 catalysts with varying Cu contents were synthesized by the one-step hydrothermal method. The physicochemical properties of the catalysts were investigated by characterizations, and the reasons for the well-activity catalysts were analyzed. The acidic sites on the SAPO-34 zeolite can adsorb and activate NH3, while the copper active sites can promote the activation and reduction of NOx, accelerating the reaction process of SCR. In this study, Cu-SAPO-34 with Cu content of n(Cu)/n(C9H21AlO3)=0.075 has good framework stability, which produced more free Cu2+ ions and the Cu species are evenly distributed on the carrier surface, and the appropriate amount of acid sites. Therefore, the Cu0.075-SAPO-34 catalyst exhibits the highest NO conversion performance, maintaining a NO conversion rate above 90 % within the temperature range of 165–450 °C.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 6","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-02-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143489696","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 fluorescence attributes, including brightness, luminescence lifetime, quantum yield, and color purity, were comprehensively evaluated.

The Au nanoparticles (with diameters around 5 nm) were synthesized by in situ reduction inside the porous structure of amorphous TiO2 films with different pores sizes and pore arrangements. The effect of oxide thermal treatment, pore size, film thickness, and the amount of embedded Au nanoparticles on the catalytic activity was evaluated, using two different model reactions. The obtained results indicate that the proper selection of the oxide thermal treatment is key to obtain stable and durable composites, with a reproducible catalytic performance. Interestingly, several synthetic conditions led to equivalent catalytic activities. In particular, the film thickness and the total amount of Au particles did not significantly affect the reaction constants, indicating that the proportion of particles involved in the catalysis is low. Since the preparation of the composites involves several steps, the fact that such variables have a weak influence on the catalytic activity results very useful in ensuring an easy production of reproducible and active catalysts.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 11","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-01-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143822329","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}

These materials exhibit notable chemical tunability and structural flexibility; however, misassignments between common phases – such as layered double hydroxides (LDHs), alpha, and beta phases – are still occasionally encountered, despite the distinct properties of each. This review focuses on the influence of crystallographic phases on the electrochemical properties of LHs, a topic that remains relatively underexplored. We discuss several synthetic approaches that allow for precise tuning of these phases, along with the most suitable characterization techniques, including synchrotron-based methods, and highlight key spectroscopic features that aid in accurate phase identification. Additionally, we provide an overview of recent work from our group, which underscores the importance of crystallographic phases in shaping the electrochemical behaviour of LHs in alkaline environments, particularly for applications such as the oxygen evolution reaction. A more detailed understanding of these phase-dependent properties is essential for the rational design of more efficient electrode materials, which could further contribute to the advancement of energy conversion and storage technologies.","PeriodicalId":38,"journal":{"name":"European Journal of Inorganic Chemistry","volume":"28 7","pages":""},"PeriodicalIF":2.2,"publicationDate":"2025-01-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143565294","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}
