Abstract
This work elucidates the influence of exposed facets of anatase-TiO2 crystals on the efficiency and selectivity of reduction of functionalised nitrobenzene derivatives. Titanium dioxide crystals in the form of bipyramids, sheets, and belts offering different exposed facets {001}/{101}, {001}, and {100}, respectively, were synthesised. Electrochemical analysis revealed a slight positive shift in the reduction potential of belt TiO2. The highest photocurrents were observed for sheets, whereas in the presence of methanol, the photocurrent doubling effect was observed for belts and bipyramids, with the most efficient methanol oxidation in the case of belts. The highest reaction rate constant for the reduction of 3-nitrophenol and 1-iodo-4-nitrobenzene was also noticed for belts. The observed differences in the resulting photocatalytic activity of nitroaromatics reduction were attributed to different efficiencies of methanol oxidation taking place at the tested photocatalysts.
期刊介绍：
Catalysis Today focuses on the rapid publication of original invited papers devoted to currently important topics in catalysis and related subjects. The journal only publishes special issues (Proposing a Catalysis Today Special Issue), each of which is supervised by Guest Editors who recruit individual papers and oversee the peer review process. Catalysis Today offers researchers in the field of catalysis in-depth overviews of topical issues.
Both fundamental and applied aspects of catalysis are covered. Subjects such as catalysis of immobilized organometallic and biocatalytic systems are welcome. Subjects related to catalysis such as experimental techniques, adsorption, process technology, synthesis, in situ characterization, computational, theoretical modeling, imaging and others are included if there is a clear relationship to catalysis.
