Abstract
Co3Se4 on nitrogen doped carbon nanotube (N-CNT) with applications for supercapacitor and hydrogen evolution reaction (HER) is synthesized by pyrolysis and solvothermal processes. The catalyst due to improved electrical conductivity and increased rate of removal of H-2 liberated, delivers a high HER activity, by reaching eta(10) at 174 mV arid 240 mV, Tafel slope of 73.2 and 43.8 mV dec(-1) in alkaline and acidic medium respectively. Co3Se4/N-CNT as supercapacitor electrodes, yields a capacitance of 114 F g(-1) at a 2 mV s(-1) scan rate, with an excellent capacitive retention of 96% of the initial capacitance after 5000 cycles.
