A Review on Cu‐Based Catalysts for Dehydrogenation of Chemical Hydrides
Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Hydrogen (H2) plays a crucial part in the building of clean and sustainable energy systems due to its advantages of being renewable, clean, and pollution‐free. Nevertheless, the secure and effective production‐storage‐transportation of H2 presents critical challenges.

Rare Metals, Volume 45, Issue 4, April 2026.ABSTRACT Prelithiation is effective for compensating active lithium‐ion (Li+) loss in silicon (Si)‐based battery electrode materials. However, owing to the dynamic growth of the solid electrolyte interface (SEI), capacity fading remains the biggest challenge for the industrialization of Si electrodes.

Zhejiang Daxue xuebao. Lixue ban, 2010 使用以煤油为油相, Span-85为表面活性剂制取的乳化液吸收甲苯废气,考察了表面活性剂浓度、进口甲苯气体浓度及喷淋液气比对吸收效率的影响,实验在填料塔中进行.结果表明,表面活性剂浓度小于2%时,表面活性剂对吸收效果影响较小,而大于2%时,随着浓度的增大吸收效率有明显的减小；进口甲苯浓度在300~900 mg • m-3的范围内,吸收效率随着甲苯浓度的提高而提高；喷淋液气比在3.0~5.0 L • m-3范围内,吸收效率随着液气比的增大而提高.在选择合适的乳化液及喷淋液气比基础上,处理浓度为300 ...
