NOVELTY - Method (M1) of converting of carbon dioxide to provide at least one product, involves reducing the carbon dioxide in a divided electrochemical cell comprising an anode in one cell compartment and a cathode electrode in another cell compartment and at least one optionally substituted aromatic heterocyclic amine, where each compartment contains an aqueous solution of an electrolyte.    USE - For converting of carbon dioxide to provide at least one product, where the at least one product is methanol, isopropanol, formic acid, formaldehyde, glyoxal or ethanol; and for producing methanol (all claimed) used as a convenient energy storage medium, readily transported and dispensed fuel (including for methanol fuel cells), feedstock for synthetic hydrocarbons and their products currently obtained from oil and gas resources (including polymers, biopolymers and even proteins, which can be used for animal feed or human consumption), and as energy storage and transportation material.    ADVANTAGE - The method allows conversion of carbon dioxide at very modest overpotentials to highly reduced species in aqueous solution; and provides simple, efficient, environmentally beneficial and economical conversion of carbon dioxide to reduced organic products, such as methanol, formic acid and formaldehyde.    DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following:    (1) a system (S1) for electrochemical or photoelectrochemical reduction of carbon dioxide to produce at least one product, comprising an electrochemical cell including a first compartment containing an anode, and a second compartment having a cathode which is a metal or p-type semiconductor, and a catalyst which is optionally substituted aromatic heterocyclic amine, where both compartments contains an aqueous electrolyte a source for providing carbon dioxide to the cathode; and an energy source supplied to the cell to reduce the carbon dioxide; and    (2) an environmentally beneficial method of producing methanol by electrochemical or photoelectrochemical reduction of any available source of carbon dioxide, involving providing a divided electrochemical cell comprising an anode in a first cell compartment and a cathode electrode in a second cell compartment that also contains a catalyst which is at least one of optionally substituted aromatic heterocyclic amine, where both compartments contains an aqueous solution of an electrolyte, providing carbon dioxide from an existing source into the second cell compartment; electrochemically or photoelectrochemically reducing the carbon dioxide in the second cell compartment to produce methanol to reducing atmospheric carbon dioxide.
