蛋白质辅助的电化学析氢催化剂的发展已在这里提出。碳纳米管（CNTs）和散装二硫化钼的表面改性与金属蛋白质细胞色素c，其中CNT-蛋白质共价功能化被发现是通过在酸性介质中的电化学循环实现的。发现MoS 2的疏水相互作用介导的表面改性产生高活性的析氢催化剂，其远远上级裸MoS 2晶体，同时与CNT官能化蛋白质催化剂相当。因此，活性催化剂的发展战略，在散装和纳米材料的工作建立。
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.
