Abstract
The catalytic efficiency of modified nanodiamonds (MND) in reactions of interaction between organic compounds was demonstrated on the example of azocoupling reaction (hydrogen peroxide-4-aminoantipyrine-phenol). It was found that catalytic action of MND was caused by redox active metal ions of Fe and Cu located on the MND surface. The neutralization of the ions significantly decreased catalytic properties of MND.
Highlights
Unique surface properties of nanodiamonds synthesized by the detonation technique [1] [2], especially the abundance of different chemically active groups and high surface area, allow us to predict the prospects for application of this nanomaterial as a catalyst

Summary
Unique surface properties of nanodiamonds synthesized by the detonation technique [1] [2], especially the abundance of different chemically active groups and high surface area, allow us to predict the prospects for application of this nanomaterial as a catalyst. We have experimentally demonstrated the applicability of nanodiamonds as catalysts for reaction of interaction between organic compounds on example azocoupling reaction: H2O2-4-aminoantipyrine-phenol. It is known that the reaction of oxidative diazotization is stimulated by the biocatalysts peroxidases [6] and accompanied by the formation of a stained reaction product (quinoneimine). Nowadays, this reaction is widely used in medical diagnostics for determination of physiologically important substances (2014) Catalytic Activity of Nanodiamonds in Azocoupling Reaction.
