In Situ Engineering an S‐Scheme MnS/MnB‐MBene Heterojunction With Spatially Separated Redox Sites for Efficient H2 Evolution and 5‐HMF Oxidation

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Photocatalytic H2 evolution coupled with biomass upgrading offers a sustainable route for clean energy conversion and high‐value chemical synthesis. Herein, an in situ grown S‐scheme MnS/MnB‐MBene heterojunction (denoted as SMx) was fabricated via alkaline etching of Mn2AlB2 followed by controlled sulfurization.

Constructing Integrative Catalytic Pairs in Carbon Nanohorns for Enhanced Neutral H2O2 Electrosynthesis

Rare Metals, Volume 45, Issue 9, September 2026.
ABSTRACT Electrosynthesis of hydrogen peroxide (H2O2) via the two‐electron oxygen reduction reaction (2e−ORR) offers a sustainable and decentralized alternative to the anthraquinone process. However, conventional solo‐active‐site catalysts are intrinsically limited by scaling relationships, imposing a trade‐off between activity and selectivity.

介质阻挡放电特性与臭氧合成的实验研究

Gaoya dianqi, 2010
采用线管结构反应器与管管结构反应器进行介质阻挡放电（DBD）产生臭氧。通过测量放电电气参数和观察辐射发光现象来研究两种反应器的介质阻挡放电特性。结合对比不同电场强度下的臭氧浓度和臭氧的生成效率,讨论两种反应器在生成臭氧应用方面的性能,实验发现线管结构介质阻挡放电特性不同于管管结构,同时臭氧浓度和臭氧生成效率取决于外加在两种反应器上的折合电场强度峰值。
