Abstract [en]

Hydrogenation is the most widely used method to reduce organic compounds. There is a demand for the development of active heterogeneous catalysts based on 3d transition metals for economical and environmental reasons. Herein, we report the first continuous-flow hydrogenation of p-nitrophenol to p-aminophenol with molecular hydrogen and heterogeneous nano-Cu2O as reducing agent and Catalyst, respectively. This reaction converts a known pollutant into a high value product with only water as by-product, which is also the solvent. One-pot synthesis methodology was adapted to prepare the catalyst, which confers sufficient nominal size for direct usage in flow reactions, which are preferred from an engineering, industrial, and environmental perspective. Catalyst reactivity was linked to difference in density-of-states between surface and bulk sites, and nanoscale size of active material.
