Pronounced catalytic activity of specially prepared MoO3–TiO2 for reduction of nitrous oxide with hydrogen

Abstract

Although an MoO₃–TiO₂(α) catalyst prepared from orthotitanic acid showed only 2·5% conversion in the reduction of nitrous oxide with hydrogen at 250 °C, an MoO₃–TiO₂(β) catalyst prepared from metatitanic acid showed 100% conversion, and its activity was markedly higher than that of MoO₃–SiO₂, MoO₃–Al₂O₃, MoO₃–MgO, or MoO₃–active carbon.
