Abstract
The developed approach to the synthesis of carbon-coated alumina is described. It includes grafting of 4,4′-methylenebis(phenylisocyanate) (MDI) due to reaction of isocyanate groups (NCO) with hydroxyl groups on the alumina surface via NC bond opening and subsequent pyrolysis of MDI surface species at 700°C in vacuum. Carbon-coated alumina supports with carbon loading up to 17.5 wt.% were synthesised by repetition of grafting–pyrolysis cycles. SEM analysis shows that surface structure of the initial alumina support is retained and no separate carbon phase is observed. It has been found out that carbon coating does not substantially influence the pore structure of the initial alumina support. The mechanism of formation of carbon coating as well as the structure of the synthesised carbon-coated alumina was studied by FTIR, TG/DTG-DTA, XPS, XRD, SEM and adsorption measurements.
