Effect of Solution pH on the Carbon Microsphere Synthesized by Hydrothermal Carbonization
Procedia Environmental Sciences, 2011 AbstractCarbon microspheres(CMSs) in a diameter of 10colonm were prepared by the hydrothermal carbonization of starch under different solution pH value. The structures and surface chemical properties of obtained CMSs before and after carbonization were characterized and compared by SEM images, nitrogen adsorption isotherms and FT-IR spectra.
