摘要

In this study, Polyethyleneimine (PEI) was utilized to modulate the electronegativity of carbon nanotubes (CNTs) through a mild method to promote its electrocatalytic performance for electrosynthesis of H2O2. The characterization results indicate the co-doping of oxygen and nitrogen elements and the CNTs-80 (modification temperature was 80 °C) catalyst exhibited the highest content of nitrogen (4.05
