Zero-emission hydrogen and oxygen production are critical for the UK to reach net-zero greenhouse gasses by 2050. Electrochemical techniques such as water splitting (electrolysis) coupled with renewables energy can provide a unique approach achieving zero emissions. Many studies exploring electrocatalysts need “electrically wire” their material measure performance, which usually involves immobilization upon solid electrode. We demonstrate that significant differences in calculated onset...
