A material for reducing the content of polluting and/or unwanted substances in a liquid includes at least one polymeric and/or inorganic base, suitable to be immersed in the liquid, having at least a surface, whereto is bonded at least one catalyst of the degradation reaction of inorganic salts in gaseous substances. The catalyst, whose function is to reduce the energy required for the activation of said reaction and to accelerate its progress, is an enzyme preferably selected among the lyase group, the hydrolase group and the oxidoreductase group. |
