A Preliminary Study on H2O2 Reactions on SIMFUEL with Different Doping Elements

Abstract

Using electrochemical measurements, we have studied the effect of different doping elements on H₂O₂ reactions on simulated spent nuclear fuels. It is observed that H₂O₂ decomposition is significantly accelerated by the doped noble metal particles. Raman spectroscopy is used to analyze the surface lattice structure, and the rare earth elements doping is found to induce defects in the sublattice structure.
