In this paper, we developed a method of one-step synthesis of Co(OH)F nanoflower on carbon cloth (Co(OH)F NF/CC) by dielectric barrier discharge microplasma as a highly efficient catalytic electrode for sensing glucose under alkaline conditions. Thanks to the microplasma-based synthesis method, only 1.5 h the Co(OH)F nano-flower obtained in situ on the carbon cloth under ambient temperature and pressure. As a non-enzymatic sensor, the Co(OH)F NF/CC electrode exhibited good electrocatalytic activity, such as shorter response time (< 5 s), low detection limit (LOD) of 0.75 mu M (S/N= 3) and response sensitivity of 1806 mu AmM-1 cm(-2) with satisfactory reproducibility and selectivity.
