This tutorial review describes studies of hydrogen production and oxidation by biological catalysts--metalloenzymes known as hydrogenases--attached to electrodes. It explains how the electrocatalytic properties of hydrogenases are studied using specialised electrochemical techniques and how the data are interpreted to allow assessments of catalytic rates and performance under different conditions, including the presence of O2, CO and H2S. It concludes by drawing some comparisons between the enzyme active sites and platinum catalysts and describing some novel proof-of-concept applications that demonstrate the high activities and selectivities of these 'alternative' catalysts for promoting H2 as a fuel.
本教程综述描述了附着于电极的生物催化剂——被称为氢化酶的金属酶——用于产氢和氧化氢的研究。它解释了如何使用专门的电化学技术研究氢化酶的电催化特性，以及如何解读数据以评估不同条件下（包括存在O2、CO和H2S的情况下）的催化速率和性能。最后，文章对酶活性位点和铂催化剂进行了一些比较，并描述了一些新颖的概念验证应用，这些应用展示了这些“替代”催化剂在促进氢气作为燃料方面的高活性和选择性。
