We compared the H production from glycerol photoreforming for different TiO polymorphs, highlighting an increase of activity in the order Pt-rutile < Pt-P25 ≈ Pt-anatase < Pt-brookite with a different distribution of the reaction intermediates. We show that the highest ability to adsorb water and the different distribution of Pt active sites in brookite can positively influence its photoactivity.
我们比较了不同TiO多晶型物在甘油光催化重整中产生氢气的情况，结果表明，反应活性按Pt-金红石型 < Pt-P25 ≈ Pt-锐钛矿型 < Pt-板钛矿型的顺序增加，且反应中间体的分布不同。我们发现，板钛矿型对水的吸附能力最强，且Pt活性位点分布不同，这对其光催化活性有积极影响。
