説明:

The heteropoly acid H4[SiW12O40] nH2O (silicotungstic acid: STA) is a strong Brønsted acid with a Keggin structure and is used as a catalyst and proton conductor. On the other hand, zirconia is a Lewis acid, which is an electron pair acceptor. Therefore, in a hybrid structure, the silicotungstic acid donates (releases) protons, and zirconia becomes a proton receiving site, allowing for the formation of a proton hopping pathway. Furthermore, in zirconium silicotungstic oxide nanorod crystals, nanoconducting paths are formed, and high-speed proton transfer can be expected. This study reports for the first time on zirconium silicotungstic oxide nanorod crystals obtained by electron beam irradiation.
