High‐Energy‐Density Redox Flow Batteries: Mechanisms, Design Strategies, and Recent Progress
Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.ABSTRACT The inherent intermittency of energy sources such as solar and wind power hinders the transition to renewable energy, necessitating advanced energy storage solutions. Enhancing energy density is crucial for lowering system costs and enabling large‐scale deployment.

Transformations of Formaldehyde Molecules in Cu−ZSM-5 Zeolites
The Journal of Physical Chemistry C, 2007 The activation of CO bond in formaldehyde molecule was followed by IR spectroscopy. IR studies showed that the interaction of formaldehyde with Cu+ weakens of the CO bond and results in a red shift...

Chemistry – A European Journal, Volume 32, Issue 23, 16 June 2026.The first microwave‐assistance‐free heterogeneous catalytic upcycling of polyoxymethylene (POM) into valuable cyclic acetals is achieved with a reusable proton‐exchanged montmorillonite (H‐Mont) catalyst. Combining interlayer accessibility with strong acidity, H‐Mont enables efficient, regenerable, and versatile transformations with potentially biomass‐

Olefin hydrogenation over zeolite H-ZSM-5.
Journal of The Japan Petroleum Institute, 1986 H-ZSM-5ゼオライトのオレフィン水素化能を調べるため, 1段目の反応管にZn-Cr系メタノール合成触媒, 2段目の反応管にH-ZSM-5 ゼオライトを充てんした2段反応装置を用いて, メタノールを経由する合成ガスからの炭化水素合成を検討した。1段目の反応圧を40kg/cm2とし, 2段目の反応圧を5～45kg/cm2と変化させたときの結果をFig. 1に示す。2段目の反応圧が20kg/cm2以上では, エタン, プロパンは生成したが, エチレン, プロピレンは全く生成しなかった。このことは, これらパラフィンがH-ZSM-5ゼオライト上で水素化あるいは水素移行反応により生成したことを示唆している。この違いを明らかにするためC2H4-H2, C2H4-Heの2種類の混合ガスをH-ZSM ...
