Metal–Organic Frameworks for Electrocatalytic Reduction of Carbon Dioxide

With the global energy demand expected to increase drastically over the next several decades, the development of a sustainable energy system to meet this increase is paramount. Renewable energy sources can be coupled with electrochemical conversion processes to store energy in chemical bonds. To promote these difficult transformations, electrocatalysts that operate at high conversion rates and efficiency are required. Metal–organic frameworks (MOFs) have emerged as a promising class of materials; however, the insulating nature of MOFs has limited their application as electrocatalysts. The recent development of conductive MOFs has led to several electrocatalytic MOFs that display activity comparable to that of the best‐performing heterogeneous catalysts. Although many electrocatalytic MOFs exhibit low activity and stability, the few successful examples highlight the possibility of MOF electrocatalysts as replacements for noble‐metal‐based catalysts in commercial energy‐converting devices. We review herein the use of pristine MOFs as electrocatalysts to facilitate important energy‐related reactions.

“…Metal–organic frameworks (MOFs) have been demonstrated as excellent precursors or carriers for SAECs 6, 7, 8, 9, 10, 11, 12, 13. In contrast to conventional electrocatalyst in the form of foil, granule, or nanoparticle, SAEC not only brings down material cost in order of magnitude scale, but also displays intriguing physiochemical properties, allowing further manipulation of the activity and selectivity of electrocatalyts 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25.…”

Electrochemical conversion of CO2 and H2O into syngas is an attractive route to utilize green electricity. A competitive system economy demands development of cost‐effective electrocatalyst with dual active sites for CO2 reduction reaction (CO2RR) and hydrogen evolution reaction (HER). Here, a single atom electrocatalyst derived from a metal–organic framework is proposed, in which Co single atoms and N functional groups function as atomic CO2RR and HER active sites, respectively. The synthesis method is based on pyrolysis of ZnO@ZIF (zeolitic imidazolate framework). The excess in situ Zn evaporation effectively prevents Co single atoms (≈3.4 wt%) from aggregation and maintains appropriate Co/N ratio. The as‐prepared electrocatalyst is featured with high graphitic degree of carbon support for rapid electron transport and sponge‐like thin carbon shells with hierarchical pore system for facilitating active site exposure and mass transport. Therefore, the electrocatalyst exhibits a nearly 100% Faradic efficiency and a high formation rate of ≈425 mmol g−1 h−1 at 1.0 V with the gaseous product ratio (CO/H2) approximating ideal 1/2. With the assistance of an extensive material characterization and density functional theory (DFT) calculations, it is identified that Co single atoms are uniformly coordinated in the form of Co–C2N2 moieties, and act as the major catalytic sites for CO2 reduction.

“…Film of tetra(4-carboxyphenyl)porphyrin Fe complex-Zr-O cluster possessed high face concentration, and as catalysts for electroreduction from CO 2 to CO, the overpotential was efficiently reduced [25]. The similar film of carboxyphenyl porphyrin Co complex-Al-O cluster supplied the same catalytic behavior [26]. Different MOFs based on tetra(4-carboxyphenyl)porphyrin Fe complex-Zr-O cluster can also be selected as catalyst in catalytic conversion from CO 2 to ethylene glycol lactone [27] [33].…”
