Abstract

A hierarchical porous material contains primary pore aggregates. The primary pore aggregates combine to form the secondary pore aggregates. The secondary pore aggregates connect to each other formed the hierarchical porous material. There are primary pores on the primary pore aggregates wherein the diameter of primary pore is 5-500 nm. There are secondary pores on the secondary pore aggregates wherein the diameter of secondary pore is 1-5 μm. The hierarchical porous material is used as oxygen reduction reaction (ORR) catalysts or photocatalysts having a significantly improved catalytic activity.
