10)：(0.01-10).Inventor has found, when the mass ratio of metal oxide and nano silver is too small, although phenolic resin base is lived
Property charcoal there is preferable bactericidal effect, but the catalytic action that PARA FORMALDEHYDE PRILLS(91,95) decomposes is limited, and excessive nano-silver ionic not only can
Increase cost, is also easy to result in waste of resources；And when the mass ratio of metal oxide and nano silver is excessive, phenolic resin base is lived
Property charcoal bactericidal effect it is limited, bacterium be easy on Carbon Materials adhere to, breed, in turn result in secondary pollution.Pass through in the present invention
The mass ratio for controlling metal oxide and nano silver is (0.01-10)：(0.01-10) can make phenolic resin-based activated carbon simultaneous
Have preferable bactericidal effect and is catalyzed the effect of formaldehyde fast decoupled.Specific example according to the present invention, metal oxide with receive
The mass ratio of meter Yin can be 2:1, thus, it is possible to further make phenolic resin-based activated carbon that there is preferable bactericidal effect and urge
Change the effect of formaldehyde fast decoupled.
It according to still a further embodiment, can be with nano-noble-metal-loaded and nanometer on phenolic resin-based activated carbon
Silver.Inventor has found that nano-noble metal equally has very high activity in catalytic decomposition formaldehyde reaction, can oxidize the formaldehyde into
Carbon dioxide is generated, and silver is a kind of anti-biotic material, especially the antibiotic property higher of nano silver.Above-mentioned implementation of the invention as a result,
It is harmful not only can effectively to adsorb bacterium and formaldehyde etc. for the phenolic resin-based activated carbon of the nano-noble-metal-loaded and nano silver of example
Molecule, and can be catalytically decomposed by nano-noble metal after formaldehyde absorbing to phenolic resin-based activated carbon surface and inside, bacterium quilt
Nano silver kills, and then can effectively avoid activated carbon that from may causing secondary pollution, and makes the phenolic resin-based activated carbon can be with
It is widely used in the field of purification such as family, industry and vehicle exhaust.
The gross mass of a specific embodiment according to the present invention, nano-noble metal and nano silver can account for activated carbon
0.01-10 weight %.Inventor has found, when the gross mass of the nano-noble metal and nano silver that are loaded on phenolic resin-based activated carbon
When very few, the catalytic action and limited to the bactericidal effect of bacterium that PARA FORMALDEHYDE PRILLS(91,95) decomposes is unfavorable for fast decoupled and the sterilization of formaldehyde,
And then bacterium can be caused to adhere on Carbon Materials, breed, secondary pollution is caused, and when what is loaded on phenolic resin-based activated carbon receives
When the gross mass of rice noble metal and nano silver is excessive, it is difficult to further increase the decomposition rate and bactericidal effect of formaldehyde, can also it make
Production cost greatly improves, and results in waste of resources, and the nano-noble metal and nano silver that load are easy to fall off.Lead in the present invention
The gross mass for crossing control nano-noble metal and nano silver accounts for the 0.01-10 weight % of activated carbon, and phenolic resin base can be made active
Charcoal can adsorb simultaneously fast decoupled formaldehyde and play preferable bactericidal effect, and the nano-noble metal and nanometer of proof load
