An ultrathin 2D semi-ordered mesoporous silica film: co-operative assembly and application

A novel ultrathin silica film with semi-ordered fingerprint-like mesopores is synthesized with the aid of the dual templates of graphene oxide (go) and tri-block copolymer P123. The formation is proposed to proceed by a co-operative assembly mechanism. As an application, the silica film is used to synthesize a 2D nitrogen-doped mesoporous carbon film, which yields superior kinetic and diffusion-limit currents than the commercial Pt/C catalyst.
