In their new study, Yi Cui and his colleagues announced advanced technology. “Our water separator is unique, because we use a single catalyst, nickel-iron oxide, for both electrodes,” said graduate student Haotian Wang, lead author of the study. "This bifunctional catalyst can decompose water continuously for over a week with a voltage of just 1,5 volts of electricity. It has demonstrated unprecedented water decomposition efficiency (82%), at temperature. ambient. "
