摘要：

Carbon coatings are synthesized on various solids via hydrothermal carbonization as a green and environmental-friendly method. The coatings can be produced on various solid substrates independent of their shape and surface properties by application of stirring during the reaction. Coatings on stainless steel felt and mesh as well as on ceramic tubes were further investigated. In their raw state, the coatings obtained have a high content of various oxygen-containing functional groups, and are somewhat lacking in surface area. However, thermal treatment creates porosity (up to 500 m(2) g(-1) specific surface area) and reduces oxygen content and density of functional groups. The heat-treated carbonaceous materials can be used as cost-efficient adsorbents in water treatment systems for adsorption of organic pollutants, with the option for regeneration through electro-thermal heating.
