Highly Selective Photocatalytic CO2-to-CH4 Conversion in Water Vapor via CeO2/Carbon Nitride Nanosheet Heterojunctions 来源：ACS PublicationsSolar-driven CO2 reforming in water vapor to produce high-value-added chemical fuels offers significant potential for renewable energy. Achieving this conversion under mild conditions can be efficiently realized through multielectron-coupled proton transfer (M-ECPT) photocatalysis. This work introduces CeO2/CNs-NKM, a composite synthesized by firmly anchoring highly dispersed cerium oxide (CeO2) onto crystalline carbon nitride nanosheets (CNs-NKM). Experime...

The YAG:Ce Phosphor Glass Prepared by a Low-Temperature Stirring Technique for WLED: Achieving High Luminous Efficiency of the Phosphor低温搅拌法制备WLED用YAG:Ce荧光粉玻璃：实现荧光粉的高发光效率来源：ACS PublicationsFluorescent glass (PiG) has emerged as an important candidate material in the field of white light-emitting diode (WLED) illumination. However, its conventional preparation processes are often complex and time-consuming, resulting in a significant performance degradation during fabrication. In this study, we carefully designed a SiO2–P2O5–Al2O3–Na2O–K2O–BaO glass composition, which was combined with Y3Al5O12...

来源：ACS PublicationsIn solid-state compounds, the valence of europium can sometimes be mixed, which is especially favored in structures with several positions for the europium atoms. In this work, we study the Eu-based intermetallic noncentrosymmetric system Eu11–xHg54+x, which has 65 atoms per unit cell and 4 distinct crystallographic positions for europium and 14 positions for mercury. Our detailed analysis of the magnetism of large single crystals suggests that europium in Eu11–xHg54+x might be present in two valence states, resulting in a fragile magnetic ground state. Due to the cage-like ...

Unlocking the Potential of Peroxymonosulfate Activation: Rare-Earth-Modulated Cobalt Species in N-Doped Carbon Catalyst for Efficient Organic Pollutant Degradation来源：ACS PublicationsThe development of efficient catalysts for peroxymonosulfate (PMS) activation remains a pivotal yet formidable challenge in advanced oxidation processes (AOPs). While Co-based catalysts are promising, their performance is often hindered by significant bottlenecks. Herein, we report a strategy of electronic structure engineering via rare-earth europium (Eu) doping to enhance the catalytic performance of Co-N-C subst...
