Abstract

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 (LOHCs), 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 o f 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 orig inal triarylborane catalysis will also be mentioned in my 
lecture 3,4
