Surface-modified carbon and adsorbents for improved efficiency in the removal of gaseous contaminants

摘要

PROBLEM TO BE SOLVED: To achieve higher adsorption and catalytic activity for removing formaldehyde and other vapors / gases from an air stream. SOLUTION: The method for producing a material for reacting with a volatile organic compound in a gas stream is (a) water with at least one manganese precursor compound together with a reducing agent in order to form metal oxide nanoparticles. It comprises a step of dissolving in a phase and (b) a step of adhering the metal oxide nanoparticles to a first porous adsorbent having pores extending inside (b), and the metal oxide nanoparticles are said. Located within at least part of the pores. [Selection diagram] Fig. 1
