One-pot synthesis of ordered mesoporous carbon/ CdS composites

Ordered mesoporous carbon/ CdS composites have been synthesized by a “one-pot assembly strategy associated with a direct carbonization process using phenolic resol as the carbon source, thiocarbamide and cadmium nitrate as matrix precursor and amphiphilictri block copolymer Pluronic F127 as a template. The composite structure was characterized by XRD, BET and TEM. The obtained mesoporous CdS/ carbon composites with ordered mesostructures have uniform pore sizes (3. 5-4. 1 nm) and high specific surface areas (554. 2 m ² / g). The CdS nanoparticles were dispersed evenly on the mesoporous carbon surface. The mesostructure ordering decreases with the increase of CdS content.
