Nature’s subtle systems drive essential reactions responsible for sustenance of our existence “reactions of life” through sophisticated mechanisms of charge transfer, energy harvest and conversion. The interconnectedness between living nature and technologically relevant electrochemical reactions, for example, oxygen reduction and evolution catalyzed by cytochrome c oxidases and photosystem II respectively, and hydrogen oxidation and evolution catalyzed by hydrogenases, does not only intrigue but also inspires us.
To what extent therefore can our present understanding of electrocatalysis guide us to decipher nature’s sophistication, or rather, can bioinspired electrocatalysis succeed to replicate and supersede nature’s per­fection “the exemplar paragon”? A harmonized perspective of the principle factors which govern electrocatalysis and bioelectrocatalysis featuring examples of technologically important electrochemical reactions catalyzed by both enzymes and inorganic electrocatalysts are presented. Sound knowledge of the inter-relationships linking electrocatalysis and bioelectrocatalysis is essential for enabling a deeper understanding of nature’s bioelectrochemical reactions, and for insightful design of functional catalysts inspired by models from living nature.
