Herein, a promising strategy is presented to couple Ir single atom with NiFe LDH/NiMo heterointerface. Ir-NiFe LDH/NiMo requires ultralow overpotentials of 139/236 mV and 350/450 mV to deliver large current densities of 500 and 1000 mA cm for HER/OER in 1 M KOH. Moreover, the electrode shows remarkable durability of 10000 cycles and long-term durability at 500 mA cm over 500 h for both HER and OER. The water electrolyzer exhibits a low cell voltage of 1.84 V to attain 500 mA cm.

Due to its remarkable characteristics, the POP-SeV was employed as a photocatalyst for visible-light-induced cross-dehydrogenative coupling (CDC) reactions with a highly efficient yield (82 %). Additionally, its utilization was further extended to the hydrogen generation, demonstrating remarkable outcomes such as a high rate of H generation (300 μmol·h·g), and an apparent quantum yield (0.13 %). Notably, POP-SeV displayed great stability and reusability in the photocatalytic process, which can distinguish it from those soluble SeV-based photocatalysts.

However, their strong oxidative ability can lead to NH over-oxidation, narrowing the active temperature range and reducing N selectivity. Moreover, their weak surface acidity hampers medium to high-temperature activity and alkali metal resistance. Hence, in this study, MnCeO metal oxides were coupled with HY zeolite to create MnCeO/HY, demonstrating excellent NH-SCR performance. The high dispersion of metal oxides on the zeolite surface and their close integration promoted strong electron interaction, effectively reducing oxygen vacancies and surface adsorbed oxygen concentrations. Consequently, the oxidative ability of active metal oxides was appropriately weakened, suppressing undesirable side reactions. MnCeO/HY also notably suppressed NO adsorption and nitrate formation, promoting the catalytic reaction solely through the E-R mechanism and enhancing N selectivity. The abundant strong acid sites on the zeolite surface facilitates NH adsorption at moderate to high temperatures, notably expanding the active temperature window. Furthermore, the acid sites of HY zeolite serve as sacrificial sites, preferentially reacting with alkali metals, thus exhibiting excellent resistance to alkali metal poisoning on MnCeO/HY. Combining with the DFT results, the structure-activity relationships in this study also reveal the importance of the effective synergy between acid sites and redox sites for optimal catalytic performance, offering valuable insights into the development of highly active and alkali-resistant denitrification catalysts.","PeriodicalId":516528,"journal":{"name":"Applied Catalysis B: Environment and Energy","volume":"59 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-08-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142205122","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
