The decomposition of hydrogen peroxide in presence of some metal oxides as a heterogeneous & heterogenized catalyst has been investigated by measuring the evolution of oxygen at different time intervals in the temperature range 30-600C. The catalytic activity is increased, an increase in the amount of catalyst and pH. The variation of H2O2 at constant pH reveals that the values of k are nearly constant irrespective of H2O2. Various parameters have been calculated .The probable reaction mechanism have been suggested in which an intermediate surface complex is thought to be responsible for the enhancement of the decomposition of hydrogen peroxide.LaCrO3 catalyst was characterized by XRD,TG/DTA,SEM,AFM.
