In a paper published in SCIENCE CHINA Chemistry, a step-scheme (S-scheme) heterojunction involving a donor-acceptor (D-A) conjugated polymer and manganese cadmium sulfide (BTz@MCS) has been fabricated to achieve efficient photocatalytic H2O2 production in a non-sacrificial system. The high photocatalytic performance of the developed catalyst is attributed to well-designed S-scheme heterojunctions with improved charge separation and transfer.
In a paper published in SCIENCE CHINA Chemistry, an indium-involved modification strategy is employed to address the instability of sulfide electrolyte and Lithium metal. The optimized doping yields a high Li-ion conductivity of 7.5 mS cm−1 for Li5.54In0.02PS4.47O0.03Cl1.5 electrolyte, accompanied by enhanced endurance against air/moisture and bare Li metal. Additionally, a composite layer comprising Li–In alloy and LiF phases is generated on the surface of lithium metal anode via the reaction between InF3 and molten Li. Consequently, the combination of the Li5.54In0.02PS4.47O0.03Cl1.5 electrolyte and the InF3@Li anode provides exceptional electrochemical performances in both symmetric cells and solid-state lithium metal batteries across different operating temperatures.
As global nitrogen pollution intensifies, scientists are seeking more effective and sustainable solutions. Recently, a review published in SCIENCE CHINA Chemistry explored the broad applications of electrocatalysis in the detection, removal, and resource recovery of nitrogen pollutants. The review emphasizes the critical role of electrocatalysis in addressing nitrogen pollution and discusses opportunities for future material innovations.
In a paper published in SCIENCE CHINA Chemistry, the strain and electronic structure of PtMnM intermetallics have been modulated by introducing another transition metal, and the optimized PtMnCo intermetallics exhibit excellent ORR activity and durability.
