A form of electrolytic manganese dioxide obtained by us from fluorine-containing electrolytes was seen to produce the higher catalytic and electrochemical activity. The catalytic activity of the synthesized electrolytic manganese dioxide was designated as the constant of rate reaction to the decomposition of hydrogen peroxide. Quantum chemical calculations of the electronic structure of molecular...
Mn1Ce1 and Mn0.9Co0.1Ce1 complex oxides were prepared by co-precipitation in hydrothermal conditions and their physicochemical properties were characterized with N2 adsorption, XRD, Raman, and SEM. The complex oxides show enough stability and catalytic activity for oxidative degradation of 4,4'-Dibromobiphenyl in sub-critical water. Mn0.9Co0.1Ce1 has higher activity than Mn1Ce1, indicating doping...
A series of CuO-CeO2 catalysts doped with transition metal oxides were prepared by co-precipitation method for selective CO oxidation and the effects of the additives on the catalytic performance were examined by H2-TPR, in-situ DRIFTS techniques. The results showed that the main CO adsorption site on CuO-CeO2 series catalysts was Cu+ species. The catalytic activity at lower temperatures was related...
In this paper, a series of catalysts LaFexAl12-xO19 were prepared by co-precipitation, in which Fe ions was the active component. The structure and properties of LaFexAl12-xO19 were investigated by using BET, XPS, XRD techniques and activities of methane catalytic combustion. The aim of the work is the comprehension of the influence of Fe ions content on the structural, morphological, and catalytic...
Catalytic systems based on activated carbon(AC) modified by manganese oxide were investigated for the hydrolysis of carbonyl sulfide (COS) in a fixed-bed reactor. The catalysts were prepared by immersion method. Effect of preparation conditions on catalytic activity were studied, including calcination temperature, content of active component, drying temperature after immersing alkali and addition...
