What kinds of carbon materials (as a cathode) are favorable for H2O2 electro-generation?

01 January 1970 1 9K Report

what kinds of carbon materials are favorable for H2O2 electro-generation? Graphite felt is a choice, but its mechanical stability is bad. Gas diffusion electrode can achieve high concentration of H2O2, but the price is high.

In electro-Fenton system, what kind of cathode is promising? Is it possible to modify graphite or graphite felt cathode for better performance to generate H2O2 by 2e- O2 reduction reaction?

Yehia F. Khalil

I would recommend using Graphene as this material has recently received lots of attention from researchers for many industrial applications including electrodes.

Hope this helps answer your question.
