Defect-driven oxygen reduction reaction (ORR) of carbon without any element doping

Zhao, Xiaojun and Zou, Xiaoqin and Yan, Xuecheng and Brown, Christopher L. and Chen, Zhigang ORCID: and Zhu, Guangshan and Yao, Xiangdong (2016) Defect-driven oxygen reduction reaction (ORR) of carbon without any element doping. Inorganic Chemistry Frontiers, 3 (3). pp. 417-421. ISSN 2052-1545


A porous carbon (PC) material, containing carbon and oxygen only, was synthesized via carbonisation of a Zn-MOF (IRMOF-8) at 950 °C. Interestingly, the derived materials of this reaction exhibit excellent electrocatalytic activity, molecular selectivity and long-term durability. The fact that this material, which is effectively a 'pure' carbon, lacking any elemental doping, exhibits excellent oxygen reduction reaction (ORR) activity suggests that a mechanism not dependent on elemental doping is being utilised. We suggest the formation of defects arising from the removal of Zn atoms as a consequence of the calcination procedure play the critical role in this process.
