Protonated ordered mesoporous carbon nitride acts as a host scaffold that forms an assembly with anionic [Mo3S13]2− clusters by taking advantage of electrostatic interactions to construct an artificial photosynthetic architecture for hydrogen production with visible light.

In this work, highly ordered mesoporous graphitic carbon (G-CMK3) has been prepared successfully by a nano-casting method using sucrose as carbon source, mesoporous silica as hard template, and soybean oil as surfactant. In the absence of soybean oil surfactant, the synthesized ordered mesoporous carbon material, CMK-3, revealed a low graphitization degree with a specific surface area of 1049.1 m2/g and a high pore volume of 1.172 cm3/g.  However, with the assistance of soybean oil surfactant, the graphitization degree was improved significantly, which was confirmed by the decrease in the ID/IG intensity ratio of the D (disordered or amorphous structure) and G (graphitic structure) peaks from 0.98 to 0.83. After the synthesis in the presence of soybean oil, G-CMK3 carbon maintained the integrity of the mesoporous structure albeit with a slight decrease in its specific surface area (845.2 m2/g) as well as pore volume (0.858 cm3/g).

Ordered mesoporous carbon (OMC) has been prepared by impregnating the pores of the silica template (SBA-15) with liquid petroleum gas (LPG) or sucrose. The desired support (OMC) was obtained after dissolution with NaOH. Platinum nanoparticles were dispersed on ordered mesoporous carbons using Chemical Vapour Deposition (CVD) method and Pt(acac)2 as metal source. The resulting ordered mesoporous carbon possess a large surface area with high microporosity, and a controlled pore size distribution, High-quality carbon replicas of SBA-15 show an X-ray diffraction peak at low angle, which indicates that the structural periodicity of the (111) planes has been maintained. Their pore volume and specific surface area are high and the pore volume is almost entirely microporous. The synthesized Pt/OMC was characterized by powder X-Ray diffraction, HR-TEM, HR-SEM, EDS, thermogravimetric analysis, and nitrogen adsorption. The performance of Pt catalyst supported OMC was evaluated by electrochemical studies, which shows almost similar activity to the commercial catalyst.
