SINOPSIS

High-concentration hydrogen peroxide is a potential substitute for a toxic hydrazine monopropellant. There is a pressing need for improved H2O2 decomposition catalysts to both increase bed loading and improve the resistance to a high temperature. In this paper, we describe the effects of Sr addition on the catalytic properties of MnOx/SrO−Al2O3 catalysts for high-concentration hydrogen peroxide decomposition. A structure analysis by temperature-programmed reduction and X-ray diffraction revealed that highly dispersed SrO formed on Al2O3 enhanced the dispersion and reduction capability of Mn species and facilitated the formation of more active Mn4+ species due to restraining the interaction between Mn and Al2O3 and activation of oxygen. Mn4+ species provided the main active site. The addition of Sr increased the catalytic activity and work stability of the MnOx/SrO−Al2O3 monolith catalyst.
