Fabrication of unique stripe-shaped mesoporous TiO2 films and their performance as a novel photo-assisted catalyst support for DMFCs

The mesoporous TiO2 films with stripe-shaped mesochannels running parallel to substrates were prepared on the FTO glass by an EISA method and studied as the catalyst support material for DMFCs, combing electrocatalysis with photocatalysis innovatively.

Anchoring Pt nanoparticles on hydrophobic ordered mesoporous carbon through solid-state reduction

Highly ordered mesoporous carbon-nickel nanocomposites have been prepared through solvent evaporation-induced self-assembly method using NiCl2 as Ni precursor. The nanocomposites maintain uniform pore structure as C-FDU-15 type and include Ni nanoparticles after a carbothermal reduction. The water contact angle of the Ni-free mesoporous carbon reaches as large as 124°, which has little change with the modification of Ni. Therefore, a solid-state reduction method is developed to load Pt nanoparticles, wherein PtCl62− with H2PO2− ions could be adsorbed to the carbon support and then in situ reduced. Electrochemical performance in sulfuric acid by cyclic voltammetry has demonstrated that this strategy is efficient to anchor Pt nanoparticles on the hydrophobic surface.
