Background
As a new concept, "carbon neutralization" has no internationally universally accepted precise connotation for a while, and a great deal of technical problems which are not in common recognition exist, the launching of the ISO 14068 standard is a long and difficult process. But anyway, the CO is consumed2Will be a key step in carbon neutralization.
Emerging technologies for the conversion of carbon dioxide, methane, and other isothermal gases into value-added products include: photocatalysis, electrocatalysis, biological mixing, and the like. Based on their findings, electrochemical technologies are closest to commercialization, and there are some pioneering and old-fashioned companies investing in this area (e.g., Opus-12, Dioxide Material and Carbon Recycling International). Over the past decade, CO2Electricity (D) fromChemical transformations have attracted attention because of several unique advantages, such as:

(2) the product can be selectively obtained by selecting specific operating conditions (e.g., electrode properties, working potential, supporting electrolyte, solvent, pH, etc.);
(3) the amplification stage is relatively easy;
(4) the process can obtain carbon-based chemicals by utilizing the surplus electric energy of intermittent renewable energy sources, stores the electric energy as chemical energy, and ideally does not need any additional fossil fuel-based power supply, thereby obviously reducing the cost process;
(5) from an environmental point of view, the production of fuels and/or chemicals by greenhouse gas conversion is expected to have less impact on the environment than current industrial processes.
