Summary: By designing a Pd/Cu2O/TiO2 ternary hybrid photocatalyst, high-efficiency and highly selective photocatalytic reduction of CO2 into CH4 is achieved, with a CH4 production rate of 42.8 mu mol g(-1) h(-1) and a selectivity of 99.5%. This is attributed to the consecutive multistep charge transfer between the Cu2O/TiO2 heterojunction and Pd in the hybrid catalyst, leading to a spatially separated electron-enriched surface (Pd) and hole-enriched surface (Cu2O) that contribute to the high conversion rate and selectivity of CH4.

Summary: An efficient Co/CoP@C catalyst with compact contact of Co and CoP layer was prepared using MOF as precursor, addressing the poor charge transfer efficiency in photocatalytic CO2 reduction. The difference in functionality between Co and CoP at the interface formed a self-driven space-charge region, ensuring spontaneous electron transfer and enhancing the utilization of solar energy. The increased electron density of active site Co in CoP promoted the adsorption and activation of CO2 molecules, resulting in a 4 times higher reduction rate of CO2 compared to CoP@C.

Summary: In this work, Cu3VSe4 nanocrystals were used to enhance laser protection performance. The nanocrystals exhibited higher saturation intensity and broader nonlinear spectral response than the C60 benchmark. A flexible optical limiter goggle prototype based on the nanocrystals significantly attenuated the incident laser beam. The excellent nonlinearity of Cu3VSe4 nanocrystals was attributed to quasi-static dielectric resonance behavior and a large two-photon absorption cross-section.

Summary: In this study, a noncoplanar antiferromagnetic phase was experimentally obtained in the antiperovskite system Mn3Sn0.5Zn0.5Cx through neutron powder diffraction analysis. This phase exhibits zero thermal expansion behavior in a wide temperature range from 10 to 162 K. The zero thermal expansion in this noncoplanar antiferromagnetic ordered system is attributed to the competition between nearest antiferromagnetic direct exchange and ferromagnetic superexchange interaction.
