Simple approach to carboxyl-rich materials through low-temperature heat treatment of hydrothermal carbon in air

[Display omitted] ► Carboxyl-rich hydrothermal carbon can be obtained by heat-treatment in air. ► Content of carboxyl groups on the heat-treated carbon can reach up to 3.70 mmol/g. ► Much higher sorption capacity for Pb and Cr is observed after heating the matrix. ► Mechanism for newly generating ca...
