One kind of transition metal / nitrogen co-doped carbon composite material for removal of formaldehyde and its preparation

摘要

This invention discloses one kind of co-doped carbon composite material with transition metal and nitrogen for removal of formaldehyde and its preparation method. The materials are composed of non-noble metals as active components and nitrogen-doped carbon carrier; The non-noble metal active components are transition metal salts of nickel, cobalt, iron and manganese or their mixtures. The carbon composite materials reported in this invention have high specific surface area and strong adsorption and catalytic decomposition performance for formaldehyde, and harsh conditions (e.g. high reaction temperature etc.) are not required for catalytic oxidation of formaldehyde. It also features in low cost, high catalytic efficiency at room temperature and long durability etc.
