PURPOSE: A manufacturing method of a metal suboxide is provided to synthesize the metal suboxide which has large specific surface area by forming a polymer on the surface of a metal suboxide precursor with reacting an aromatic compound which is substituted to a hydroxy radical and a connection precursor. CONSTITUTION: A metal suboxide has more than 1.5m^2/g of a specific surface area. The metal suboxide includes less than 1 weight% of carbon base on the total weight of the metal suboxide. The metal comprises a transition metal, a post-transition metal, and one selected from a combination thereof. The metal suboxide comprises pore. The manufacturing method of the metal suboxide comprises the following steps. A mixture which includes a metal suboxide precursor (1), aromatic compound which is substituted to a hydroxy radical (3), and a connection precursor is manufactured. The polymer (13') is formed on the surface of the metal suboxide precursor by reacting the aromatic compound which is substituted to a hydroxy radical and the connection precursor. The polymer is heat treated. A carbon is removed from the polymer. In the step of manufacturing the mixture which includes a metal suboxide precursor, aromatic compound which is substituted to a hydroxy radical, and a connection precursor; the connection precursor comprises one selected from C1 to C30 aldehyde, C3 to C30 ketone, and combination thereof.

PURPOSE: A heavy metal absorbing agent, a method for manufacturing the same, and a filtering device comprising the same are provided to supply edible water by selectively absorbing and removing heavy metal ions from water containing minerals. CONSTITUTION: A heavy metal absorbing agent comprises heavy metal absorbing particles and a nitrogen oxide (NOx) functional group. The heavy metal absorbing particles are selected among inorganic oxides, graphite-based carbon, and a combination thereof. The nitrogen oxide functional group is applied to the surfaces of the heavy metal absorbing particles. In the NOx functional group, x is between 1 and 2, inclusively. The inorganic oxides are oxides containing atoms selected among transition metals, rare-earth metals, alkaline metals, alkaline earth metals, 13-group atoms, 14-group atoms, and a combination thereof. The heavy metal absorbing agent is nanoparticles with 1-100nm particle sizes. [Reference numerals] (AA) Permeability (%); (BB) Wave number (cm^-1); (CC) Example 1
