Effect of pore orientation on proton conductivity of porous phosphosilicate glass films

Mesostructured HSO 3 -functionalized TiO 2 -P 2 O 5 sol-gel films prepared by evaporation induced self-assembly method with high proton conductivity

“…Since the high conductivities of the inorganic thin-films can be attributed to proton hopping between the hydroxyls groups of the surface and water molecules absorbed in the pores, the pore structure is essential for determining proton conductivities [22]. Therefore, the development of proton exchange membranes with high conductivity, and performance stability at high temperature is a very critical component in this area [23].…”

Proton-Conducting Solid Electrolyte via Ozonolysis of Cationic Ammonium Organoalkoxysilane Surfactant-Templated MCM-41

“…These materials that typically contain sulfonated aromatic groups, which are placed onto the silica surface via grafting or through cocondensation of organosilanes with the silica precursores used in the synthesis, suffer from desulfonation and low loadings (<1.8 mmol/g). In order to overcome these limitations, preparation methods involving alkyl sulfonation 5 and the use of other acidic groups such as phosphoric acids 8 and doped nitrogen heterocycles 9 have been examined.…”
