Facile Oxygen Reduction on a Three‐Dimensionally Ordered Macroporous Graphitic C3N4/Carbon Composite Electrocatalyst

Abstract
Honeycomb catalysis: A facile oxygen reduction reaction has been observed on a graphitic C3N4/carbon catalyst with three-dimensional interconnected macropores (see picture with SiO2 template). This material not only shows catalytic activity that is comparable to that of commercial Pt/C, but also has much higher organic-fuel tolerance and long-term stability.
