Abstract—The products of redox reactions that occur during the manufacture of opal-matrix nanocomposites
in isopropanol under supercritical conditions are studied. Experimental data, thermodynamic calculations, and
reaction yield values imply that hydrogen is formed in the catalytic dehydrogenation of isopropanol to acetone
under supercritical conditions. The alcohol dehydrogenation catalysts are ultrafine d-element oxides encapsu-
lated in the pore space of an ordered opal matrix; in a closed experimental system (an autoclave), these oxides
are reduced by hydrogen to metals or to lower oxides (or the oxygen stoichiometry of higher oxides changes).
