Nanocatalysis in continuous flow: supported iron oxide nanoparticles for the heterogeneous aerobic oxidation of benzyl alcohol

Author affiliations

Abstract

Investigations on heterogeneous iron catalysis in the selective aerobic oxidation of a primary alcohol are presented. Continuous flow technology was used in combination with an iron oxide nanoparticle catalyst stabilized in a mesoporous aluminosilicate support (“flow nanocatalysis”) as a process intensification tool to maximize catalyst efficiency. Using 5 mol% 2,2,6,6-tetramethylpiperidine-1-oxyl (TEMPO) as a co-catalyst, up to 42% benzyl alcohol as a simple model substrate was selectively converted to benzaldehyde in a single pass of the reactor. Full conversion was achieved by continuous recirculation, simulating an extension of the catalyst bed. ICPMS analysis indicated that the catalyst is highly stable and does not leach under the investigated conditions, providing solid evidence for the participation of a heterogeneous iron species in the catalytic cycle.
