In this study, ordered mesoporous carbon (OMC) was prepared via nano-casting method by using Santa Barbara Amorphous (SBA)-15 as a template and sucrose as a carbon precursor. The OMC was subsequently oxidized with aqueous nitric acid and referred as MOMC. The physicochemical properties of OMC and MOMC were determined using nitrogen adsorption–desorption analyser, field emission scanning electron microscopy (FESEM), transmission electron microscopy (TEM), and Fourier transform infrared spectroscopy (FT-IR). The results proved that the carbon replication process was successful. The electrochemical performance tests were carried out using cyclic voltammetry (CV) and galvanostatic charge–discharge (GCD) in 1 M KOH electrolyte for 1000 cycles. After oxidative treatment, the specific surface area and pore volume of OMC decreased but the specific capacitance of the electrode material has significantly increased from 117      F g–1 to 344 F g–1 at a scan rate of 10 mV s–1.

Electron Microscopy Analysis

Cu-modified graphitic ordered mesoporous carbon supported TiO2 catalyst was synthesized based on a hard template method. X-ray diffraction, nitrogen adsorption-desorption, scanning electron microscopy and transmission electron microscopy analysis techinques were used to characterize the sample. It was observed that copper and anatase TiO2 nanoparticles were well dispersed in the Cu-modified mesoporous graphitic carbon, and the resulting composite with ordered mesostructure and high specific surface area exhibited an exceptionally high activity in the photocatalytic reduction of CO2 with H2O under simulated solar irradiation.

Coating Method

Ordered mesoporous carbon nanospheres with uniformly penetrating channels have been successfully synthesized by a nanocasting method using mesoporous silica as a template. The ordered mesoporous carbon nanospheres were investigated as electrode materials for supercapacitors via high-resolution transmission electron microscopy, nitrogen adsorption and desorption isotherms and a variety of electrochemical testing techniques. The electrodes with ordered mesoporous carbon nanospheres prepared by coating method exhibited good rate capability and reversibility at high scan rates in electrochemical performances. Ordered mesoporous carbon nanosphere electrode with specific surface area of 904 m2/g maintained a stable specific capacitance of 210 F g-1under specific current of 0.1 A g-1for 500 cycles of charge/discharge.
