1. A method of killing pathogens, comprising:
providing a structure that comprises an open-cell polymer foam;
incorporating biochar into the open-cell polymer foam or coupling biochar to the structure;
impregnating the open-cell polymer foam of the structure with a hydronium-based disinfectant that is configured to kill pathogens; and
exposing the disinfectant-impregnated open-cell polymer foam of the structure to the pathogens such that the disinfectant-impregnated open-cell polymer foam of the structure contacts and kills the pathogens.
