Angew Chem Int Ed Engl. 2013 Sep 27;52(40):10505-10. doi: 10.1002/anie.201303353. Epub 2013 Aug 13.

Abstract

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.

Keywords: biosensor; block copolymers; mesoporous materials; niobium; resol.
