Cover Story: This study developed a novel composite membrane fabricated from graphitic carbon nitride (g−C3N4) and Nafion and applied it to steam electrolysis with excellent results. g−C3N4 is uniformly dispersed among the non-homogeneous functionalized particles of the polymer, and it improves the thermostability of the membranes. The amino and imino active sites on the nanosheet surface enhance the proton conductivity. Above 100 °C, the modified membranes exhibit high conductivity, and no sudden decreases in conductivity are observed. The Nafion/g−C3N4 membranes exhibit excellent performance when utilized as a steam electrolyzer. Compared with that of previous studies, this approach achieves better electrolytic behavior with a relatively low catalyst loading. View this paper
