Al2o3 Catalyst

The concept of very strong metal–support interactions (VSMSI) was defined in regard to the interactions that influence the catalytic properties of catalysts due to the creation of a new phase as a result of a solid-state chemical reaction between the metal and support. In this context, the high catalytic activity of the 1%Pt/Al2O3 catalyst in the CO oxidation reaction at room temperature was explained. The catalyst samples were reduced at different temperatures ranging from 500 °C to 800 °C and characterized using TPR, O2/H2 titration, CO chemisorption, TPD-CO, FTIR-CO, XRD, and TOF-SIMS methods. Based on the obtained results, it was claimed that with very high temperature reduction (800 °C), nonstoichiometric platinum species [Pt(Cl)Ox] strongly anchored to Al2O3 surface are formed. These species act as the oxygen adsorption sites.

Cod Removal Rate

The influence of methanol on the sludge removal rate of COD was investigated and the mechanism was obtained. The results show that the adding of methanol solution can improve the sludge COD removal rate, when the mass fraction of methanol is 5%, COD removal rate can be highly 99.98% compared 98.26% of that without methanol. The mechanism of co-oxidation is that methanol oxidation process can produce free radicals HO· and HO2·, they attack intermediate phenol and acetic acid, promote acetic acid to C-C bond fracture and ring-opening of phenol.
