摘要
纳米级TiO2作为一种光催化材料,在环境保护、光能转换、纺织建筑、工业催化等领域有着极为广泛的用途,其制备方法也得到了深入系统的研究。文章简要介绍了近年来纳米二氧化钛的制备方法、掺杂改性途径以及在卫生保健、废水处理、有机气体降解、新型材料制备等应用中的最新进展,并展望纳米二氧化钛今后的研究方向。
Nano-TiO2 is applied widely in many fields such as environment protection, transition of light-energy, textile and architecture, industrial catalyst. The developments of new preparations and new doped methods to modify properties in recent years are generalized and applications at aspects of hygiene, purifying waste water, organic polluted air degradation and preparations of novel materials are introduced briefly in this paper. At last the directions are proposed about the studies of nanosized TiO2 in the latest years. Transition metals and rare earth elements are widely used to attempt to modify nano-TiO2 powders which can lead to favourable social benefit, benign environmental benefit and nice economic benefit in the future.
