An oxygen-nitrogen co-doped hollow carbon nanoparticle and a preparation method therefor and an application for electrosynthesis of hydrogen peroxide. Carbon nanoparticles are taken as a base material, firstly, in an oxygen-containing atmosphere, high-energy oxygen plasma generated by radio frequency (RF) excitation bombard the surface of the carbon nanoparticles, forcing carbon-carbon bonds in the carbon material to break and exerting a strong ablation effect on graphite layers of carbon, thereby forming a special hollow carbon structure. After an oxygen doping reaction is finished, the oxygen-containing atmosphere is switched to a nitrogen-containing atmosphere to prepare an oxygen-nitrogen co-doped hollow carbon nanoparticle catalyst.
