Nowadays, it is a great challenge to eliminate toxic and harmful organic pollutants from air and water. This paper reviews the role of TiO2 as a photocatalyst, light source and photoreactor in the particular case of removal of formaldehyde using the photocatalytic reaction by titanium dioxide (TiO2) in aqueous and gaseous systems. The reaction mechanisms of the photocatalytic oxidation of gaseous formaldehyde are given. We also present a detailed review of published articles on photocatalytic degradation of formaldehyde by modified titanium dioxide doped with foreign species such as metal and non-metal components. We point out the most prospective developments of the photocatalyst compositions for the future potential commercial applications.
如今，从空气和水中去除有毒有害有机污染物是一项巨大的挑战。本文综述了二氧化钛（TiO₂）作为光催化剂、光源和光反应器，在水相和气态体系中通过二氧化钛（TiO₂）光催化反应去除甲醛这一特定情况下所起的作用。给出了气态甲醛光催化氧化的反应机理。我们还对已发表的关于掺杂金属和非金属等外来物种的改性二氧化钛光催化降解甲醛的文章进行了详细综述。我们指出了光催化剂组合物未来潜在商业应用中最具前景的发展方向。
