Chemical and physical properties of the measured coal samples. A The size and morphology of CD-MPs and CD-NPs were observed with SEM. B The size distribution of CD-MPs and CD-NPs were measured with a Malvern Nanoparticle Size Potentiometer. C The elemental composition of CD-MPs and CD-NPs was analyzed by energy X-ray spectrometer.
