CO2 Recycling: The Conversion of Renewable Energy into Chemical Fuels

We want to bring the idea of conversion of CO2 into synthetic fuels (CO2 recycling) into attention, as a possible approach for transportable storage of renewable energy. Recycling of CO2 by homogeneous and/or heterogeneous catalytic approaches have been investigated with increasing emphasis within the scientific community. In the last decades, especially using organic and bioorganic systems towards CO2 reduction has attracted great interest. Chemical, electrochemical, photoelectrochemical, and bioelectrochemical approaches are discussed vividly as new routes towards the conversion of CO2 into synthetic fuels and/or useful chemicals in the recent literature. Here we want to especially emphasize the new developments in bio-electrocatalysis with some recent examples.
