Abstract: An ocean iron fertilization (OIF) method and system for electrochemically controlled release of iron in an ocean to stimulate growth of phytoplankton to increase CO2 sequestration by the ocean. The system includes a cathode submerged or floating in the ocean; an iron or iron-producing anode submerged or floating in the ocean spaced apart from the cathode; and a power supply unit connected to the cathode and the anode. The power supply unit drives electric current between the cathode and the anode such the anode generates oxygen (O2) and ferrous iron through electrolysis to be released in the ocean, and the cathode produces hydrogen (H2) and hydroxide (OH—) species through an electrochemical reaction at the cathode.

Abstract: Disclosed is a method of removal of an organic pollutant from an aqueous solution, comprising: a) contacting the solution with an anode and a cathode comprising a carbon material; b) applying electrical current to the anode, thereby generating reactive oxygen species; b) oxidizing the organic pollutant with the reactive oxygen species; and c) regenerating the carbon material. Also disclosed is a method of producing reactive oxygen species, comprising: a) flowing an aqeous solution through a reactor comprising at least one cathode and at least one anode; b) applying electrical current to the at least one anode; and c) collecting a product solution comprising reactive oxygen species.
