Basic metal carbonates are attractive supports for gold nanoparticles, resulting in excellent catalytic properties in liquid-phase alcohol oxidation under mild conditions. The basic support can replace the use of soluble bases such as potassium carbonate. The catalytic activity of gold nanoparticles on basic hydrozincite is considerably higher than that of titania- or ceria-supported gold. The high catalytic activity is related to the presence of accessible, strong basic sites. The initial bond cleavage is thought to occur on the basic sites of the support. This approach is promising to develop a truly heterogeneous catalyst for alcohol oxidation because soluble bases can be replaced in a straight forward manner by a solid support.
