In summary, we have developed a new effective electrocatalyst for OER, r-BS+G exhibits a low overpotential (250 mV) at 10 mA cm^-2, and when introducing Ni foam as the supporting material, it shows much better activities and strong durability (over 100 h). Such good performance of r-BS gives a new strategy to study high-efficient electrocatalysts for future potential applications.
