Doping strategy, properties and application of heteroatom-doped ordered mesoporous carbon

Abstract

To date, tremendous achievements have been made to produce ordered mesoporous carbon (OMC) with well-designed and controllable porous structure for catalysis, energy storage and conversion.

Preparation of Sulfur‐doped Carbon for Supercapacitor Applications: A Review

“…These methods are generally categorized into three broad aspects: in-situ synthesis, posttreatment method, and CVD. [75] In the in-situ synthesis, the precursors having natural sulfur or compounds containing sulfur are thermally treated with templates to generate a wellordered intermediate composite, followed by carbonization at high temperature (> 500 °C). [76] The in-situ approach produces simultaneous sulfur doping and porous carbon structure.…”

“…As a result, in this section, we will concentrate on sulfur doping strategies in carbon and the associated process characteristics, such as thermal treatment, hydrothermal method, biomass‐assisted synthesis, polymer‐assisted synthesis, template‐assisted synthesis, microwave‐assisted synthesis, electrochemical method, solvothermal method, supercritical fluid‐assisted synthesis, flame pyrolysis technique, sol‐gel processing, chemical vapor deposition (CVD) method, and wet chemical route. These methods are generally categorized into three broad aspects: in‐situ synthesis, post‐treatment method, and CVD [75] . In the in‐situ synthesis, the precursors having natural sulfur or compounds containing sulfur are thermally treated with templates to generate a well‐ordered intermediate composite, followed by carbonization at high temperature (>500 °C) [76] .…”

Synthesis and Characterization of Supercapacitor Materials from Soy

“…The G peak, also called the graphitic band, is representative of sp 2 carbon pair stretching modes. Carbon doping and activation affects surface carbon proportion due to the formation of functional groups via interaction of surface carbon with doping elements and gases formed in the high temperature environment, which causes carbon bond cleavage and formation with reacting species [51,52]. The defect ratio between the integration of these two peaks, I D /I G , gives information related to the degree of doping for the sample.…”

Multi-functional O2–H2 electrochemistry by an abundant mineral: a novel and sustainable alternative for noble metals in electrolyzers and metal–air batteries

“…20,21 Such treatments are not only sensitive 22,23 but also involve the risk of inhomogeneity. 24 In the context of all of the above complexities, doping cannot be regarded as a favourite synthesis strategy for the economical and scalable industrial production of catalysts. Thus, a material does not become an ideal electrocatalyst by merely being multifunctional and transition metal-free but essentially when produced through low energy consumption and facile routes.…”
