大自然微妙的系统通过复杂的电荷转移、能量收集和转换机制，驱动着负责维持我们存在的基本反应——“生命反应”。生物自然与技术相关的电化学反应之间的相互联系，例如分别由细胞色素c氧化酶和光系统II催化的氧还原和进化，以及由氢化酶催化的氢氧化和进化，不仅引起了我们的兴趣，而且给了我们灵感。因此，我们目前对电催化的理解能在多大程度上指导我们破译大自然的复杂性，或者更确切地说，生物启发的电催化能成功地复制和取代大自然的完美“典范典范”吗？在这里，我们提出了一个统一的观点，支配电催化和生物电催化的主要因素，并以酶和无机电催化剂催化的技术上重要的电化学反应为例。充分了解电催化和生物电催化之间的相互关系，对于更深入地理解自然界的生物电化学反应，以及从自然界的模型中获得灵感，设计出有见地的功能催化剂至关重要。(C) 2016 Elsevier Ltd.版权所有。
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 inter-connectedness 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"? Herein, we present 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. 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.
