The hydrogenation of citral has been performed over Ru–Fe catalysts supported on activated carbon and on high-surface-area graphite. It was found that selectivity to unsaturated alcohols is independent of the carbonaceous support used for ruthenium catalysts. The addition of iron enhances selectivity to unsaturated alcohols (geraniol and nerol) in a manner similar for both ruthenium catalysts, becoming maximum for the highest ...
