Templated pores : A resol‐assisted solvent‐evaporation‐induced self‐assembly (RA‐EISA) gives unique ordered mesoporous niobia spheres by using the amphiphilic diblock copolymer PEO‐ b ‐PS as a template. The mesoporous Nb 2 O 5 spheres have ordered hexagonal structures, large pore size and high surface area, and a nanocrystalline framework (see picture). They show excellent electrochemical sensing of hydrogen peroxide.
