- Enhancing alkane oxidation using Co-doped SnO2 nanoparticles as catalystsPublication . Silva, Telma F.S.; Silvestre, A. J.; Rocha, Bruno G. M.; Nunes, Manuel R.; Monteiro, Olinda; Martins, LuisaA novel eco-friendly KA oil synthesis at room temperature (up to 25% yield) via solvent-free cyclohexane oxidation using Sn1 − xCoxO2 − δ (x = 0, 0.01 or 0.05) nanoparticles as catalyst (TON up to 2 × 103) is here reported. These nanoparticles are the first SnO2-based material able to catalyze the oxidation of alkanes. The most active nanocatalyst was the Sn0.95Co0.05O2 − δ, allowing an easy recovery and reuse, at least for five consecutive cycles, maintaining high selectivity concomitant with 92% of its initial activity.
