Active Sites Derived from Heteroatom Doping in Carbon
This chapter describes the recent advancements with regard to heteroatom-doped carbons and discusses the active sites decorated in the carbon matrix in terms of their configurations and contents, as well as their effectiveness in boosting the ORR performance. Furthermore, trace metal residues and metal-free catalysts for the ORR are clarified.
Insights into the Use of Te–O Pairs as Active Centers
The ultra-dense carbon defects (HDPC) (2.46 × 10 cm) in the derived porous carbon served as efficient active sites for oxygen reduction, resulting in an excellent catalyst in both base
Doping strategy, properties and application of heteroatom
Many publications have demonstrated that the synergistic effects of co-doping heteroatoms could provide more active sites and additional functional groups as well as promote the surface wettability for OMC compared to the single doping, which create excellent electrochemical behavior. 10,11 In most of co-doping cases, the hard template is
Synthesis and design of biomass-derived heteroatom-doped
The process of heteroatom doping can be used to effectively increase capacitance by reducing G Na min or increasing U (Eq. (6) and Fig. 6 e). The predicted and experimentally obtained specific capacitances corresponding to heteroatom-doped carbon systems were normalized against the specific capacitances of the undoped carbon systems (Fig
- Which electron site is activated by heteroatom doping?
- The sp 2 C, with abundant free-flowing π electrons, is deemed to be one of the active sites of PS activation on undoped carbon materials, and sp 2 C could be further activated by heteroatom doping to attain higher catalytic potential. B doping is believed to further heighten the π electron activity of NG .
