The progress and outlook of bioelectrocatalysis for the production of chemicals, fuels and materials

Bioelectrocatalysis is a green, sustainable, efficient method to produce value-added chemicals, clean biofuels and degradable materials. As an alternative approach to modern biomanufacturing technology, bioelectrocatalysis fully combines the merits of both biocatalysis and electrocatalysis to realize the green, efficient production of target products from electricity. Here, we review the development status of bioelectrocatalysis, discussing the current challenges and looking toward future development directions. First, we detail the structure, function and modification methods of bioelectrocatalysis. Next, we describe the mechanism of electron transfer, including mediated electron transfer and directed electron transfer. Third, we discuss the impact of the electrode on bioelectrocatalysis. Then we analyse and summarize the application of bioelectrocatalysis methods in the production of chemicals, biofuels and materials. Finally, we detail future developments and perspectives on bioelectrocatalysis for electrosynthesis.
