1. From hydrothermal carbonization to blue hydrochars and activated carbons : Adsorption of volatile organic compounds and heavy metals
Abstract : Hydrothermal carbonization of carbohydrate and biomass is a straightforward method for preparing hydrochars at low temperature. Hydrochars are more carbonized than their precursors. Hydrochars themselves are carbon precursors for preparing activated carbons. Activated carbons are porous materials that can be used for water and air purification. READ MORE
