Abstract

<abstract abstract-type="main" xml:lang="en"> <title>Abstract</title> <p>MnO₂ was synthesised as a catalyst support material using a hydrothermal method. This involved reacting MnSO₄<bold>⋅</bold>H₂O and (NH₄)₂S₂O₈ at 120 °C for a range of crystallisation times, which affords control over the morphology and phase composition of the MnO₂ formed. Gold was deposited on these supports using sol‐immobilisation, impregnation and deposition precipitation methods, and the resultant materials were used for the oxidation of benzyl alcohol and carbon monoxide. The effect of the support morphology on the dispersion of the gold nanoparticles and the consequent effect on the catalytic performance is described and discussed.</p> </abstract>
