Abstract
Ni-, Co- and Ni–Co-containing catalysts for steam reforming of isobutanol were obtained by biochar impregnation with water-alcohol solutions of metal salts. Biochar was synthesised by the hydrothermal carbonisation of cellulose with subsequent thermal treatment of the obtained materials under the conditions of limited oxygen access. The catalysts were characterised using a complex of physicochemical methods (IR spectroscopy, BET, temperature programmable desorption of ammonia, scanning electron microscopy in combination with local electron microprobe analysis, X-ray phase and X-ray fluorescence analysis). It is found that the sample 2.5Ni-2.5Co/C (where the number before the metal symbol means its mass content calculated for the mass of reduced catalyst, %) provides a high yield of hydrogen (58%) from isobutanol reforming.
