内容記述
Repeated washing with ethanol and hexane of polyvinylpyrrolidone (PVP)-capped Pt nanocolloid could generate an uncovered Pt surface. Pt dispersion was significantly improved by this washing as compared to unwashed Pt. IR spectrometry revealed that PVP-free Pt supported on SiO2 could be obtained by calcination at 200 ℃, while unwashed Pt required more than 250 ℃.
