The electrochemical reactors disclosed herein provide novel oxidation and reduction chemistries and employ increased mass transport rates of materials to and from the surfaces of electrodes therein.

A water treatment apparatus includes: a reaction vessel that contains water to be treated, including an upper part from which the water to be treated is introduced and a lower part from which the water to be treated is discharged, to form a downward flow; an ozone supply unit that supplies ozonized gas into the reaction vessel from the lower part to form an upward flow of the ozonized gas containing ozone gas and oxygen; and an electrolysis electrode pair disposed on the upper part of the reaction vessel, the pair that produces hydrogen peroxide from the water to be treated and the oxygen gas contained in the ozonized gas by electrolysis.

The present invention provides a hydrogen peroxide production method and a hydrogen peroxide production kit that are capable of producing hydrogen peroxide more efficiently and at lower costs than conventional methods. Specifically, the present invention provides a hydrogen peroxide production method comprising: (1) a hydrogen peroxide generation step of generating hydrogen peroxide by irradiating a reaction system containing water, an organic polymer photocatalyst, and O.sub.2 with light, wherein (2) the organic polymer photocatalyst comprises an organic polymer having a structure such that a monocyclic or polycyclic aromatic compound and/or a monocyclic or polycyclic heteroaromatic compound is/are linked by a bridging group, and (3) the organic polymer has a band structure such that a conduction band (CB) has a potential lower than the potential of two-electron reduction of O.sub.2, and a valance band (VB) has a potential higher than the potential of four-electron oxidation of water.

The present invention relates generally to an advanced oxidation process for providing advanced oxidation products to an environment. More particularly, the present invention provides a wick structure and hydrophilic granules for use in an advanced oxidation process, and methods of making the same. The wick structure and hydrophilic granules may be configured to collect and concentrate water vapor, so that the water vapor may subsequently be used to generate advanced oxidation products that react with and neutralize compounds in an environment, including microbes, odor causing chemicals, and other organic and inorganic chemicals.
