“…Au/Al 2 O 3 catalysts were also observed to display activity in the direct formation of hydrogen peroxide by the reaction of H 2 and O 2 at low temperature. [100][101][102][103][104][105][106][107][108] However, this catalyst gave low selectivity based on H 2 utilisation and was much poorer in terms of catalyst performance when compared with supported Pd catalysts which had, up to that date, been studied for this reaction. Indeed, studies concerning the direct formation of hydrogen peroxide using Pd catalysts date back for almost a century.…”

Heterogeneous catalysis plays a key role in the manufacture of essential products in key areas of agriculture and pharmaceuticals, but also in the production of polymers and numerous essential materials. Our understanding of heterogeneous catalysts is advancing rapidly, especially by using the latest characterisation methods on these relatively complex effect materials. At the heart of these catalytic processes, both selective oxidation and hydrogenation play a key role. Both oxidation and hydrogenation exhibit similar requirements since often a partial reaction product is required, rather than the products of total hydrogenation or oxidation, in the latter case this being typically carbon dioxide and water. This Feature Article considers the approaches available for catalyst discovery and design for heterogeneous catalysts. Three catalysts are considered in detail, two exemplifying oxidation and the other selective hydrogenation. The design of vanadium phosphates for the selective oxidation of butane to maleic anhydride is described in terms of the search for advanced materials with superior activity. This is achieved through the synthesis of wholly amorphous vanadium phosphates. The design of supported gold and gold palladium alloy catalysts for the oxidation of carbon monoxide and the direct hydrogenation of oxygen to form hydrogen peroxide is described and the problems concerning selectivity control are discussed.

“…Supported Au catalysts have been investigated for the oxidation of propene to propene oxide using O2/H2 mixtures (39), and it is considered that a surface hydroperoxy species may be formed as the oxidant. We have found that supported Au catalysts can be very effective for the synthesis of hydrogen peroxide (40,41) and, furthermore, the rate of hydrogen peroxide formation can be significantly enhanced by the use of a supported Au/Pd alloy.…”

In the last decade there has been an explosion in the interest shown in catalysis by gold. It is now recognised that gold has unique properties as a catalyst for many reactions with pre-eminence in heterogeneous catalytic oxidation. This paper sets out the general content of a keynote lecture delivered at the second world congress on gold in Vancouver in 2003. The background to this significant interest is discussed and the early work in the field is placed in context. The current areas of interest are described and two reactions, namely the oxidation of glycerol to glyceric acid and the formation of hydrogen peroxide from the oxidation of molecular hydrogen, are discussed. The prospects for future discoveries are also considered.

“…Recently, there is evidence in the literature and in the patent application that gold based catalysts are applied effectively for this purpose [7,8,21,22 , is 3,6 for 1.3 wt% Au/TiO 2 at reaction temperature of 303 K [22], whereas 5wt% Au/Al 2 O 3 show a similar productivity but at lower temperature (Tr = 275 K) [8].…”

“…The identification of direct route for the synthesis of H 2 O 2 from the reaction of O 2 and H 2 would be highly beneficial. There is evidence in the literature and in the patent application that gold based catalysts are applied effectively for this purpose [7,8,21,22]. Hutchings has reported the use of Au catalysts supported on various supports, included iron oxy-hydroxides, for the direct synthesis of hydrogen peroxide from O 2 and H 2 .…”
