摘要

A simple and environmentally friendly new method, a low-heating solid-state chemical method (LSCM), has been used to prepare uniform NH₄TiOF₃ nanoplates with a thickness of about 100 nm in the absence of surfactants. The solid–solid transformation was used to convert NH₄TiOF₃ nanoplates to TiO₂ nanoplates with an exposed (001) facet via a simple sintering process at different temperatures. The anatase TiO₂ nanoplates obtained in this work have super heat-stability, and can withstand high temperatures and maintain highly active anatase up to 1000 °C. The obtained compact TiO₂ nanoplates have high photocurrent density and photocatalytic hydrogen-production activity, better than as-prepared TiO₂ porous nanoplates and reported values in the literature, which is due to the exposed (001) facet and the high degree of crystallinity. This work provides a simple, efficient and environmentally friendly way to prepare TiO₂ nanoplates and nanoparticles, and also offers a new approach for preparing anatase TiO₂ with super heat-stability and high reactivity, which can be applied to H₂-production via photocatalytic water splitting.
