Abstract Anthropogenic activities powered by the burning of fossil fuels have caused excessive emissions of carbon dioxide (CO2) to the atmosphere. This has a negative impact on our environment. One promising approach to reduce the concentration of atmospheric CO2 is to convert it to useful products. This could be achieved via the electrochemical reduction of CO2 using renewable electricity. Methanol (CH3OH), a valuable fuel and feedstock, is one of the CO2 electroreduction products. However, its formation, thus far, has been plagued by the inadequacy of functional electrocatalysts. In this review, we summarize progresses made in the development of methanol-selective electrocatalysts, which provides us with a basis to discuss the underlying challenges of electroreducing CO2 to methanol.

This paper reports the development of an electrochemical reactor for electrochemical reduction of carbon dioxide using anionic and cationic solid electrolyte. Cast nafion membrane was used as cation exchange membrane and alkali doped polyvinyl alcohol cross-linked with glutaraldehyde was used as anion exchange membrane. The anion exchange membranes (solid electrolytes) were characterized using TGA, XRD, FTIR, anionic conductivity, and mechanical strength. The anode electrode was prepared using Pt/C spraying over porous carbon paper. The cathode electrode was prepared using copper electroplating technique over porous carbon paper. The prepared electrodes were characterized using scanning electron microscope. The reactor was assembled with the electrolyte, electrodes, machined graphite plates, and end plates with the required accessories. The preliminary study of the reactor was evaluated for carbon dioxide electrochemical reduction under anionic and cationic electrolytes. The products of the electrochemical reduction of CO2 were analyzed using GC and HPLC.

Photocatalytic Synthesis

Copper nanoparticles frequently exhibit unique electrocatalytic activity for the electrochemical reduction of carbon dioxide. However, the synthesis of Cu nanoparticles in aqueous systems remains rare. Herein, we report the synthesis of copper nanoparticles by using a zinc(II) porphyrin-based photocatalytic method in the presence of polyacrylic acid sodium salt (PAA) in water under visible light irradiation, leading to a series of Cu nanoparticles with relatively small average sizes ranging from 69 to 97 nm. PAA molecules adsorbed on Cu nanoparticles were simply removed by washing with copious amount of water. The purified Cu nanoparticles show some activity toward the electrochemical reduction of carbon dioxide as evidenced by linear sweep voltammetry (LSV) and gas chromatography (GC).

Reduction Of Co2

The electrochemical reduction of CO2, which includes a number of different specific approaches, may show promise as a means to help slow down the accumulation of this greenhouse gas in the atmosphere. Two types of approaches are examined briefly here. First, CO2 can be used as a reagent in the electrocarboxylation reaction to produce organic carboxylic acids, for example, the pharmaceutical ibuprofen. Second, CO2 can be converted to a fuel, either directly or via synthesis gas. The latter can be produced with reasonably good energy efficiency in a gas-diffusion, electrode-based cell even at present with existing electrocatalysts. Oxygen gas is produced as a by-product. Further work is needed to improve the selectivity and efficiency in this and other approaches.
