Direct Epoxidation of Propene over Goldtitania Catalysts: a Transient Study of the Reaction Mechanism
Gold-titania based catalysts for the direct epoxidation of propene provide a clean and simple route for future propene oxide producing processes. These catalysts, producing propene oxide in a single step, have a moderate activity and a very high selectivity towards propene oxide. However, the hydrogen, which is used as a co-reactant, is used less efficient. To be able to improve the hydrogen ef...

متن کاملSimultaneous in situ generation of hydrogen peroxide and Fenton reaction over Pd-Fe catalysts.
High mineralization degree of organic compounds can be achieved by a novel environmentally-friendly full heterogeneous Pd-Fe catalytic system, which involves in situ generation of hydrogen peroxide from formic acid and oxygen, and oxidation of organic compounds by Fenton process in a one-pot reaction.

calculation for each term and their sum which contribute to AG are reported in Table 11. In any case, the entropy of the reactions is unfavorable and particularly for photoreduction in CO. The enthalpy, AH, is calculated in Table 111 from the energy balance of the bonds created and destroyed in reactions 13-16. The Ni-O and Ni-CO bond energies are taken as 24 and 30 kcal mol-' from theoretical ...
