A resol-assisted co-assembly approach to crystalline mesoporous niobia spheres for electrochemical biosensing.
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 Nb2O5 spheres have ordered hexagonal structures, large pore size and high surface area, and a nanocrystalline framework. They show excellent electrochemical sensing of hydrogen peroxide.
