Direct synthesis of phenol by hydroxylation of benzene with oxygen and hydrogen was investigated on precious metals supported on silica. On Pd, Rh, Ir and Pt, phenol was formed with a large amount of water. Modification of the catalyst was studied with various metal oxides. When the catalyst was mod

Phenol is one of the most important chemicals in industry, and the world production exceeds 7.2 megatons per year. Industrially, phenol has been produced from benzene by the threestep cumene process, which is not only energy consuming but also less efficient. The process is known for its very low yi
Benzene hydrogenation was studied at 323 K on fresh and sulfurixed catalysts. The activity of small platinum and iridium particles was sensitive to the electronic properties of the metal, which, in turn, depended on the acidity of the support. The toxicity of sulfur, which varies with both the natur
Benzene hydroxylation with hydrogen peroxide catalyzed by selectively site-substituted vanadium V polyoxometalates was classified into two reaction types based on the turnover vs. time curve with or without an induction period. A prototypic example was the catalysis by the two geometrical isomers of
