Cover Picture: Highly Efficient Reversible Hydrogenation of Carbon Dioxide to Formates Using a Ruthenium PNP‐Pincer Catalyst (ChemCatChem 6/2014)

Abstract

Milder, faster, stronger, better! The cover shows a conceptual hydrogen battery in which H2 storage and its release are achieved through reversible catalytic hydrogenation of CO2 with an Ru‐PNP pincer complex. In their Communication on E. A. Pidko et al. describe a homogeneous catalytic system that shows unprecedented activity in both CO2 hydrogenation and dehydrogenation of HCO2H. The authors describe a key role of the base promoter on the reaction mechanism, the overall performance of the system, and its H2 storage capacity.
