ABSTRACT: Cobalt-Boron oxides containing catalyst CoO·B2O3 (CoB2O4) are synthesized for hydrogen generation by catalytic reforming of basic
solution of sodium hypophosphite (NaH2PO2) and identified
by chemical and X-ray analysis. Reforming is performed in temperature range of
30°C - 80°C. Reaction rate constants at each value of temperature
(k30°C = 8.53 × 10?4 s?1; k40°C = 1.62 × 10?4 s??; k50°C = 3.06 × 10?3 s?1; k60°C = 5.06 × 10?3 s?1; k80°C = 1.39 × 10?2 s?1), temperature
coefficient of rate of chemical reaction (γ = 0.917) and activation energy (EA = 49.59 kJ·mol?1) are calculated.
