Summary: A new Pb-free perovskite material with a wide range of visible-light absorption was successfully synthesized via hydride (H-) ion doping. The material showed a significant reduction in optical band gap and a clear anodic photoresponse when used as a photoelectrode material, demonstrating its potential for photofunctional applications. The utilization of stereoactive lone pair of electrons in combination with H- doping may provide another approach to the band gap reduction of Sn(IV)-based oxides, which are nontoxic and less expensive, but generally wide-gap semiconductors.

Summary: The MCM-48/ZnFe2O4/BiOBr (MZBB) heterojunction photocatalyst was used to decompose rhodamine B (RhB) under visible light. The compound semiconductor degraded RhB by 99.03% after 60 min at a concentration of 40 mg/L and pH 6.0, with a total organic carbon (TOC) mineralization rate of 0.0631. The combination of n-type ZnFe2O4 and BiOBr improved the photocatalytic performance of the MCM-48/ZnFe2O4/ BiOBr composite, and the presence of n-n junctions promoted the separation of photogenerated carriers and prolonged recombination time.

Summary: In this work, a double design host and guest strategy is proposed to enhance the electrochemical properties of sulfur electrodes in sodium ion storage. The V2O3 adsorbent immobilizes sulfur species, while the selenium dopant improves the electronic conductivity and redox conversion of sulfur cathodes. The synergistic effect between the V2O3 adsorbent and selenium dopant inhibits the shuttle effect and improves the redox kinetics, resulting in greatly enhanced Na-ion storage properties of sulfur cathodes. The as-designed sulfur cathode exhibits excellent rate capability of 663 mA h g(-1) at 2.0 A g(-1) and exceptional cyclability of 405 mA h g(-1) over 700 cycles at 1.0 A g(-1).

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.
