摘要: Cobalt-containing MCM-41 and SBA-15 mesoporous materials were prepared by the pH-adjusting of impregnation solution. The modified investigated X-ray diffraction, N2 physisorption, temperature-programmed reduction, DR UV–Vis diffuse reflectance, FT-IR spectroscopy adsorbed pyridine. pH solution influences surface charge support therefore determines strength interaction between cobalt precursor support. formation different oxide species in ratios, depending on solution, was established for both materials. Co/MCM-41 Co/SBA-15 active toluene oxidation. Their catalytic activity is predetermined nature, reducibility, dispersion obtained species.
