查询词典 Titanic

Pt-inserted nanotube titanic acid was prepared as follows: H_2PtCl_6 ethanol solution was filled into the titanic acid nanotubes and then annealed in air at 673 K for 3 h.X-ray photoelectron spectroscopy showed that H_2PtCl_6 has been converted to Pt~0 and PtO.The result of electron spin resonance revealed that there are single-electron-trapped oxygen vacancies to be formed in PNTA after heat treatment in air.
