Synthesis of graphitic mesoporous carbon from sucrose as a catalyst support for ethanol electro-oxidation

Abstract

Graphitic mesoporous carbon (GMC) has been prepared with non-toxic and economical sucrose as the carbon precursor and mesoporous iron oxide as a catalyst at a relatively low carbonization temperature. XRD patterns suggest that GMC is formed by a carbide intermediate. The data of nitrogen sorption exhibit that the GMC possesses a mesoporous structure. Pt nanoparticles are uniformly loaded on the graphitic mesoporous carbon by a facile and effective microwave assisted ethylene glycol process. All the results show that the graphitic mesoporous carbon-supported Pt nanoparticles have superior electrocatalytic properties compared to Vulcan XC-72 and CMK-3 catalyst supports, suggesting this novel and general method will have a bright future in fuel cell applications.

The Enhanced Catalytic Performance and Stability of Ordered Mesoporous Carbon Supported Nano‐Gold with High Structural Integrity for Glycerol Oxidation

“…Figure shows the FT‐Raman spectrum of NCCR‐56, in which two distinct signals at 1287 cm −1 and 1587 cm −1 corresponding to D1‐band and G‐band, respectively are observed. The presence of broad D1‐band corresponding to a graphitic lattice vibration mode with A 1g symmetry in the spectra indicate the possible disordered arrangement of carbon in the pore walls leading to the loss of hexagonal symmetry of the graphitic framework structure . Furthermore the D2 band for both the carbons corresponds to a defective graphitic lattice mode with E 2g symmetry.…”

Synthesis and characterization of graphitic mesoporous carbon using metal–metal oxide by chemical vapor deposition method

“…The band at 1350 cm À1 corresponds to the D-band and assigned to the A 1g phonon is weak which reveals the high purity of the synthesized GMC. The relative intensity ratio of the D band vs the G band (I D /I G ) for GMC is less than 1, indicating that GMC is composed of small graphene sheets with a high degree of graphitization [15,32,33]. The degree of graphitization increased with increasing the metal concentration over the support then decreased.…”
