Yoichi Hoshimoto – MBLA Lecture

Our team recently demonstrated a strategy to separate H₂ from a gaseous mixture of H₂/CO/CO2/CH₄ that can include an excess of CO and CO₂ relative to H₂ and simultaneously store it in N-heterocyclic compounds that act as liquid organic hydrogen carriers (LOHC_s), which can be applied to produce H₂ by subsequent dehydrogenation.¹ Our results demonstrate that LOHCs can potentially be used for H₂ purification in addition to their well-established use in H₂ storage. Moreover, this work demonstrates a new aspect of main group catalysis beyond its application as a simple alternative to well-established transition metal-catalyzed processes, i.e., the main group–catalyzed hydrogenation of unsaturated molecules (e.g.,carbonyl compounds)² under mixed gas conditions. Recent progress on our original triarylborane catalysis will also be mentioned in my lecture. ^3,4
