Abstract

In this study, the electrolysis of industrial wastewater was carried out at different voltages for green hydrogen production rate (HPR). Voltages selected for the study are 1.3 V, 3 V, 6 V, 9 V, 12 V, and 15 V. It was found that at a high voltage range, the electrolytic hydrogen production rate was high, but the efficiency of the system did not follow a similar trend of increase with selected wastewater. It was found that with an increase in voltage (1.3 V to 15 V) the HPR increased up from 0.05 ml/hr to 8.45 ml/hr while the highest optimized efficiency of 20.68 % was achieved at 3 V with carbon electrodes.
