Abstract In this work, the metastable aqueous-aqueous interfacial approach was used to prepare MnO2 with enhanced surface area, which helps to save energy, decrease cost and protect the environment. The material characteristic success was proven through using powder X-ray diffraction for the crystalline properties and N2 adsorption-desorption isotherm for high surface area. The relationship between the calcination temperature and the crystallinity as well the specific material surface area was also interested. The catalytic decomposition of hydrogen peroxide was investigated by the closed system measuring produced oxygen. After the H2O2 decomposition comparison between synthesized samples and commercial MnO2 in terms of both the efficiency and the speed, the M-200 sample was considered as a typical sample with outstanding performance to examine the reaction conditions (H2O2 solution concentration, catalyst amount and reaction temperature). The optimal reaction condition results are 0.9% H2O2 solution concentration, 0.2g/L catalyst, and room temperature. Besides, the leaching test and the catalytic regeneration were also conducted.

A mesoporous La2Sn2O7-HT pyrochlore with an unusually high surface area was successfully synthesized with a simple hydrothermal method at 200 °C. Due to its high surface area and the presence of more active oxygen species, Pd supported on this mesoporous La2Sn2O7-HT shows remarkable CO oxidation activity.
