A bifunctional graphene catalyst with abundant topological defects is achieved via the carbonization of natural gelatinized sticky rice to probe the underlying oxygen electrocatalytic mechanism. A nitrogen‐free configuration with adjacent pentagon and heptagon carbon rings is revealed to exhibit the...
