Quantum Anomalous Hall States in Li/Na-Doped Kagome V3X8 (X = Cl, Br) Monolayers J. Alloys Compd. (IF 5.8) Pub Date : 2025-02-09 Huijie Lian, Xiaokang Xu, Jinlian Lu, Xiaojing Yao, Ailei He, Xiuyun Zhang
The quantum anomalous Hall (QAH) insulators have great potential in low-energy electronic devices due to their dissipationless conducting channels. By carrying first-principles calculations, we predict that Li/Na-doped two-dimensional kagome lattice V3X8 (X = Cl, Br) monolayers, V3X8@Li(Na), are intrinsically ferromagnetic (FM) half-semimetals with out-of-plane magnetic anisotropy. Interestingly, the

CeO2-Ni2Co1Sex Catalysts Grown on N-Doped Carbon Substrates for Electrocatalytic Oxidation of Methanol and Urea J. Alloys Compd. (IF 5.8) Pub Date : 2025-02-09 Ruixia Cao, Ying Chang, Jingchun Jia
Methanol or urea electrolysis provides the foreground of more economical and energy-efficient hydrogen production, while alleviating the pollution of methanol-rich or urea-rich wastewater, which is also critical to solving environmental problems. Efficient and inexpensive electrocatalysts designed for methanol oxidation reactions (MOR) and urea oxidation reactions (UOR) can not only alleviate energy
