Carbon dioxide conversion into useful products has been gaining considerable attention as a global‐warming‐mitigation technique. The electrochemical conversion of CO2 into high‐value chemicals involves the utilization of electrical energy in the presence of an effective catalyst. The process products depend on the number of transferred electrons during the reaction and the characteristics of the electrode. Recently, electrodes coupled with active catalysts have been used to convert CO2 into valuable products including formic acid, hydrocarbons, and syngas. This review offers an overview of the recent literature on the electrochemical conversion of CO2 to valuable products, with an emphasis on the production of formate/formic acid. In addition, it compares the main features of electrochemical conversion to other techniques and summarizes their key advantages. It also provides future perspective for research and development, such as the need for novel and selective catalysts to obtain high conversion and product yield with low energy consumption.

“…In addition, their surfaces contain abundant functional groups, which can act as preferred nucleation sites for the crystallization of semiconductor photocatalysts. The development of MoS 2 /CNFs, [ 35 ] Co/CNFs, [ 36 ] Ni/CNFs, [ 37 ] Cu/CeO 2 /CNFs, [ 38 ] and ZnIn 2 S 4 @CNFs [ 39 ] show great promise for photocatalytic H 2 evolution. Nevertheless, the weak interface bonding, reduced active sites, and unsatisfactory interfacial transportation efficiency of charge carrier inevitably occur when directly loading catalytic materials onto the CNFs substrate.…”

Hierarchical three‐dimensional (3D) carbon nanofibers (CNFs)/molybdenum disulfide (MoS2)/ZnIn2S4 composites with p–n heterojunctions between the basal planes of two‐dimensional (2D) phases are fabricated, using in situ spinning‐based chemical vapor deposition together with hydrothermal processing. It is found that large and intimately interfaced 2D–2D planes between the n‐type ZnIn2S4 and the CNFs‐supported p‐type MoS2 enable evident junction rectification effect, which facilitates interfacial charge separation to assist effective suppression of the recombination of photogenerated electrons and holes. In addition, the p‐type MoS2 nanosheets with high in‐plane conductivity and narrower bandgap are highly effective in providing larger quantities of photoinduced electrons, which can be readily injected into the outer n‐type ZnIn2S4 coating for the reduction of H2O into H2, whereas the holes are driven into the CNF cores by the junction field to be finally scavenged. The large specific surficial area of the sulfides provides abundant sulfur‐rich sites active for H2 evolution. Consequently, the optimal CNFs/MoS2/ZnIn2S4 composite with 5 mmoL MoS2 loading exhibits robust H2 evolution under simulate sunlight irradiation, achieving a remarkably enhanced photocatalytic H2 production rate over 151.42 mmoL⋅h−1⋅g−1 and a high apparent quantum yield of 20.88% at 365 nm, which is 4.65 times higher than that of pristine ZnIn2S4.
