Léonard’s article about O2-tolerant bioelectrochemical CO2 reduction was published in EES Catalysis (read her paper here). His paper demonstrates that a combination of enzyme immobilisation on functionalised electrodes, maintaining the enzyme in a reduced state and using tailored solvents enables efficient and robust electrochemical CO2 reduction with a highly senstivie carbon monoxide dehydrogenase enzyme, even when the CO2 contains up to 14% O2.

Astha’s article about a waste-derived photocatalyst for hydrogen evolution was published in ACS Sustainable Resource Management (read her paper here) and is featuerd on the supplementary cover. This paper demonstrates how a nanocomposite from waste coffee grounds (an abundant resource in the Kühnel Lab) and an anthraquinone-base covalent organic framework acts as an active catalyst for solar-driven hydrogen evolution from pure water. This COFfee catalyst forms a Z-scheme type heterojunction with improved charge separation and much improved performance compared to the pure COF that requires 75% less photocatalyst to produce the same amount of hydrogen.
