Diamond-like carbon (DLC) films as electrochemical electrodes

Amorphous carbon can be any mixture of carbon bonds of sp3, sp2, and even sp1, with the possible presence of hydrogen. The group of mixture, of which there is a high fraction of diamond-like (sp3) bonds, is named diamond-like carbon (DLC). Unlike the crystalline carbon materials: diamond, graphite, carbon nanotube, fullerene and graphene, DLC can be deposited at room temperature without catalyst or surface pretreatment. Furthermore, its properties can be tuned by changing the sp3 content, the organization of sp2 sites and hydrogen content, and also by doping. This paper firstly reviewed the electrochemical properties of DLC films and their applications.
