摘要: Abstract Gold deposited on various oxides with high dispersion was found to be active for the hydrogenation of CO 2 at temperatures between 150 and 400°C. Product selectivities greatly depended nature support oxide. Acidic like TiO gave higher conversions but low methanol yields. Zinc oxide component indispensable selective synthesis. Significantly, large particle size effect gold observed smaller particles productivity per exposed surface area gold. This can explained by an increase in perimeter a decrease size. Methanol yield enhanced Au/ZnOTiO catalyst probably due gold-zinc interface.
