Well-dispersed hollow porous carbon spheres synthesized by direct pyrolysis of core–shell type metal–organic frameworks and their sorption properties†
Abstract
Well-dispersed hollow porous carbon (HPC) spheres are prepared by the pyrolysis of polystyrene@ZIF-8 core–shell microspheres. The resulting HPC spheres have high surface areas and show tremendous methylene blue adsorption ability due to the lack of agglomeration, excellent dispersion, and high surface-to-volume ratio.
