报告摘要： 

Conductive diamond is one of the most promising electrode materials, stemming from its wide potential window, high stability in different solutions and under harsh conditions, tuneable surface terminations, rich surface chemistry, and the possibility to form composites with other materials. Therefore, conductive diamond and their composites have been extensively employed in different electrochemical fields such as chemical/biochemical sensing, environmental degradation, energy storage and conversion.  

In this presentation, the progress and achievements of conductive diamond and its composites that have been obtained in our group will be shared. This talk will start from the properties of conductive diamond and its composites, followed by the experimental details of their synthesis by means of chemical vapor deposition techniques. After briefly showing the characterization results of these diamond materials, their applications in the fields biosensing (e.g., direct electrochemistry of protein, DNA biosensing), electrochemical energy storage (e.g., supercapacitors featuring both high power- and energy- densities), and electrochemical energy conversion (e.g., electrocatalysis and the construction of flexible zinc-air batteries) will be highlighted. The future research directions of diamond electrochemistry will be also discussed and outlined.
