Dutch researcher Ferry Winter has developed a heterogeneous catalyst for the production of the industrially important solvent methyl isobutyl ketone. With the new catalyst the production process is more environmentally-friendly. The catalyst consists of hydrotalcite, a naturally-occurring clay.
The catalyst developed by Ferry Winter belongs to a new category of catalysts termed activated hydrotalcites. Hydrotalcite is a clay comprised of a mixture of magnesium and aluminium hydroxide and forms a layered compound. After activation the clay can be used as a solid-base catalyst. Winters catalyst is made up of very small hydrotalcite platelets deposited on carbon nanofibres. This structure gives rise to a highly active catalyst, which in terms of catalyst particle size and mechanical strength is ideally suited for industrial applications.
