A facile and replicable stepwise chemical method was explored to synthesise magnetically separable Ru-based nanocatalyst. Structural investigation revealed that nanocatalyst is a hierarchical multiphase nanocomposite, consisting of highly magnetic Fe3C (and Fe) nanoparticles, distributed within a high-surface-area graphitic carbonaceous matrix, uniformly decorated with superiorly active catalytic ruthenium nanoparticles and clusters. The nanocatalyst showed an improved catalytic activity and selectivity for the hydro-deoxygenation of bio-resource-related compound eugenol when compared to the commercial Ru/C. In combination with ultrafast magnetic separation, it holds a good emerging potential in the valorisation of renewable resources and recycling of noble metals.

The well-designed magnetically separable Ru based nanocatalyst is synthesised using simple and scalable chemical method without using surfactants and toxic reagents, which demonstrate high catalytic activity and ultrafast magnetic separation.
