“…Therefore, synthetic procedure was modified in an attempt at increasing surface area. In a previous paper on the syntheses of titania-based catalysts the ageing method of the gel was found to be crucial to modify surface area and to influence on crystallinity of the resulting systems [13]. Application of different ageing methods to the syntheses of our systems resulted in an increase in surface area, as evidenced in Table 1.…”

“…Some other minor products, whose mechanisms of formation are described elsewhere [12] were acetaldehyde, propene and carbon dioxide with traces of methanol and acetic acid. Under the same experimental conditions [13] commercial Degussa P25 titania exhibited ca. 45% initial conversion and a selectivity to acetone of ca.…”

“…Metals should better have low overpotential for H 2 . Strong metal support interaction also improves the efficiency of the metal as electron scavenger helping in the decrease of electron/hole recombination in semiconductors photocatalysis [17,27,28]. However, the recombination rate increases at high metal loading because the distance between trapping sites in a particle decreases with the amount of metal, so that an optimum exists [29].…”

This paper focuses on the application of photocatalysis to hydrogen production from organic substrates. This process, usually called photoreforming, makes use of semiconductors to promote redox reactions, namely, the oxidation of organic molecules and the reduction of H + to H 2 . This may be an interesting and fully sustainable way to produce this interesting fuel, provided that materials efficiency becomes sufficient and solar light can be effectively harvested. After a first introduction to the key features of the photoreforming process, the attention will be directed to the needs for materials development correlated to the existing knowledge on reaction mechanisms. Examples are then given on the photoreforming of alcohols, the most studied topic, especially in the case of methanol and carbohydrates. Finally, some examples of more complex but more interesting substrates, such as waste solutions, are proposed.

“…Sonication enabled the synthesis of pure anatase nanoparticles with increased surface areas, which influence the photocatalytic performance. Further pursuits included not only titanium tetra-isopropoxide, but also titanium tetrachloride as titanium precursor, employing MS, US, microwave (MW), and reflux methodologies for the sol-gel aging procedure [79]. The synthetic protocol was optimized and applied to the generation, by coprecipitation, of a Pt-doped TiO 2 system that was evaluated against the selective photoxidation of propan-2-ol in the gas phase.…”

Merging Metallic Catalysts and Sonication: A Periodic Table Overview

Abstract:This account summarizes and discusses recent examples in which the combination of ultrasonic waves and metal-based reagents, including metal nanoparticles, has proven to be a useful choice in synthetic planning. Not only does sonication often enhance the activity of the metal catalyst/reagent, but it also greatly enhances the synthetic transformation that can be conducted under milder conditions relative to conventional protocols. For the sake of clarity, we have adopted a structure according to the periodic-table elements or families, distinguishing between bulk metal reagents and nanoparticles, as well as the supported variations, thus illustrating the characteristics of the method under consideration in target synthesis. The coverage focuses essentially on the last decade, although the discussion also strikes a comparative balance between the more recent advancements and past literature.
