Reactions of titanium dioxides with water molecules have been studied by matrixisolation infrared and density functional theoretical calculations. In solid argon, titanium dioxide molecules reacted with water to form OTi(OH)2 molecules spontaneously on annealing. The potential energy surface along the TiO2+H2O→OTi(OH)2 reaction path was calculated. Although titanium dioxide–water complex was predicted
通过基质隔离红外和密度泛函理论计算研究了二氧化钛与水分子的反应。在固态氩气中,二氧化钛分子与水反应,在退火时自发形成OTi(OH)2分子。计算了沿着TiO 2 + H 2 O→OTi(OH)2反应路径的势能面。尽管预计二氧化钛与水的络合物是稳定的,但由于低能垒和高水解反应放热性,未观察到该络合物。还提供了形成OTi-OH 2复合物的证据。
