About this collection
This collection is edited by Associate Editor Professor Carlos D. Garcia (Clemson University) and contains selected Reviews, Communications and full Papers published since 2018. The collection features the most remarkable contributions published in the journal and aims to highlight recent work published and raise awareness of the most current strategies to mitigate the impact of CO2 on the atmosphere.
These articles describe strategies to either promote the capture of CO2 or its reduction to yield organic compounds of higher value (methane, methanol, carbon monoxide, and short-chain organic acids). Although most of these articles describe clever chemical reactivity, their main focus ranges from biomimetic approaches to electrochemistry and photocatalysis.
