Abstract EN
The kinetics of decompositIon of hydrogen peroxide have been studied over different electrodeposited nickel powders catalysts characterized by different particle sizes and morphological structure.
The reaction was confirmed to be first-order and the decomposition rate constant was found to be dependent on the surface morphology of the catalyst.
The thermodynamic parameters of activation were calculated.
The energy of activation showed little variation with different samples.
The entropies of activation have moderate negative values.
The change in .15* is of the same order as that of .1W.
The compensation relationship between T .15* against .1H* showed that there is small change in .10* with catalyst samples.
The mechanism of the reaction was discussed in the light of previous results.
This mechanism involves an electron transfer from the metal to the H202 adsorbed at the interface.
