Abstract
The catalytic properties in H2O2 decomposition of Ni2+‐chelates of the following ligands have been investigated: ethylenediamine, diethylenetriamine, triethylenetetramine, 2,2′‐bipyridine, pyrophosphate and ethylenediamine‐N, N, N′, N′‐tetra‐acetic acid, and of the following peptides and peptide‐like ligands: glycylglycine, N,N′‐diglycyl‐ethylenediamine, N, N′‐diglycyl‐1, 5‐diaminopentane and polymyxin B.
