Carbon capture, utilization, and storage (CCUS) is an important emissions reduction technology that can be deployed in the industrial sector and in the power generation. By converting the CO in the atmosphere into value-added hydrocarbons with high energy density and ease of transportation and storage, CO utilization has witnessed a sharp rise in the amount of public and private spending on R&D programs and projects. Copper has been proved as the only known electrocatalyst that can catalyze the CO into hydrocarbons with adequate efficiency and selectivity. In this review, we will begin with an introduction of some background to the electrochemical CO reduction reactions (ECR) process. Followed by a discussion of the world’s energy status, we then focus on the advances for the optimization of the Cu-based electrocatalysts that generate multi-carbon products to meet the requirements of the industry from the point-view of electrolyzer design, electrocatalysts design and electrolyte design. Afterwards, we highlight the in-depth understanding of the electrocatalytic process combining theoretical methods and in-situ/operando experimental approaches. Finally, we present the challenges by discussing how they can be overcome to achieve a carbon-neutral economy.
