- W2492688052 abstract "Abstract Improving the performance of mostly employed anatase TiO 2 photocatalysts by properly controlling their crystal shape represents a big challenge to improve their efficiency in photocatalytic applications. After the synthesis, reported in 2008, of anatase microcrystals enriched in high-energy {001} facets, many efforts have been made aimed at tuning the crystal morphology of anatase, by means of either fluorine-mediated or more environmentally friendly methods, producing a deviation from its regular crystal growth. In this relatively new field of investigation, controversial opinions emerged concerning the role of each type of facet and its relative amount in relation to photoefficiency optimization. This review addresses this topic by presenting a critical survey of selected literature reports. After a brief introduction on the main synthetic strategies adopted to obtain shape-controlled anatase photocatalysts, the attention is focused on the methods employed for their comprehensive characterization, including the identification and quantification of exposed facets and the assessment of their influence on bulk and surface properties relevant to photoactivity. Potential interferences, derived from synthetic routes and possibly affecting the conclusions of facet-dependent photoactivity investigations, are also discussed. Key examples of test reactions actually demonstrating how both the type and/or the amount of specific facets influence photocatalytic activity are finally reported, aiming at providing rational bases for the design of better performing shape-controlled anatase photocatalysts." @default.
