Selectivity engineering in the synthesis of value added chemicals: Oxidation of 1-octanol to 1-octanal over nano-fibrous Ag-OMS-2 catalysts

► Air oxidation of 1-octanol to 1-octanal was studied in a fixed bed catalytic reactor in vapour phase at atmospheric pressure. ► Cryptomelane octahedral molecular sieve-2 was modified with different Ag loading (5-15%, w/w) to get nano fibrous materials. ► All catalysts were fully characterized. ► 10% Ag-OMS-2 was the most selective catalyst. ► It was necessary to use toluene as a diluant to increase the selectivity.
