Revealing the atomic-scale configuration modulation effect of boron dopant on carbon layers for H₂O₂production

Abstract

This work reports an atomic-scale carbon layer configuration tuning strategy induced by a boron dopant. Through regulating the doping level of boron, it was found that the boron dopant not...

Boron-Doped Biomass Carbon Nanostructures as Electrocatalysts for the Two-Electron Oxygen Reduction Reaction

“…36,37 Compared to B s -C (1.09), f-B p -C (0.68), and f-pure C (0.73), the I D /I G ratio of f-B s -C (0.50) was greatly smaller, indicating a higher degree of graphitization; this also proves that the transient ultrahigh temperature process is beneficial in improving the graphite degree of carbon material. 38 Meanwhile, the two-dimensional sheet structure of BNs properly promoted the graphitization of carbon material by acting as a substrate in f-B s -C. 39,40 Through X-ray photoelectron spectroscopy (XPS), we further investigated the chemical composition and heteroatom configuration, and the elemental contents of all samples are summarized in Table S1. In Figure 2g S1.…”
