In this work, we show that the introduction of acidic oxygen functionalities to the surface of carbon nanofibers serves to depress the hydrogenation and the decomposition of hydrogen peroxide during the direct synthesis of H2O2. Furthermore, the presence of acidic groups enhances the H2O2 productivity in the case of supported AuPd nanoparticles.
