Protein assisted electrochemical hydrogen evolution catalyst development has been proposed here. The surfaces of carbon nanotubes (CNTs) and bulk MoS₂ are modified with the metalloprotein cytochrome c, where the CNT–protein covalent functionalization is found to be attained via electrochemical cycling in acid medium. The hydrophobic interaction mediated surface modification of MoS₂ is found to produce a highly active hydrogen evolution catalyst, much superior to bare MoS₂ crystals while on par with CNT functionalized protein catalysts. Hence a strategy for active catalyst development which works both in bulk and nanomaterials is established.

细胞色素C原位修饰大块或纳米材料表面以进行活性氢释放催化

在此提出了蛋白质辅助电化学放氢催化剂的开发。碳纳米管（CNTs）和大量MoS _2的表面被金属蛋白细胞色素c修饰，发现通过酸性介质中的电化学循环可实现CNT-蛋白共价功能化。发现疏水相互作用介导的MoS _2的表面改性可产生高活性的析氢催化剂，远远优于裸MoS ₂晶体，而与CNT官能化的蛋白质催化剂相当。因此，建立了一种在本体和纳米材料中都起作用的活性催化剂开发策略。
