Abstract: A composite material comprising a carbon layer and spherical carbon/carbon cloth (C-SC/CC) was fabricated using a hydrothermal-pyrolysis method, employing carbon cloth as the substrate and glucose as the carbon source. The C-SC/CC electrode was evaluated as an electrocatalytic electrode for hydrogen production by electrolysis of Bunsen reaction products. The electrode prepared with 4 g of glucose and annealed at 800℃ showed excellent electrocatalytic activity. It requires only a potential of 185 mV (vs. SCE) to achieve a current density of 10 mA/cm2. Furthermore, the electrode demonstrated good stability with a 6% loss in current density after 1000 cycles of scanning from 0.2 V to 1.2 V. These results indicate the potential of the SC/CC electrode as an efficient and durable electrocatalyst for the electrolysis of H2SO4 and HI.
