“…The electrochemical CO 2 RR of contrast samples are measured adopting the same testing methods. To evaluate the impact of Co-TCPP in electrochemical CO 2 RR, NNU-12 {[PMo 8 V Mo 4 VI O 36 (OH) 4 Zn 4 ][BCPT] 2 ∙xGuests} is prepared 46 . NNU-12 with dia topology is constructed by Zn-ε-Keggin and BCPT 2- linker, which contains the same Zn-ε-Keggin unit as Co-PMOF while the ligand is different.…”

The design of highly stable, selective and efficient electrocatalysts for CO2 reduction reaction is desirable while largely unmet. In this work, a series of precisely designed polyoxometalate-metalloporphyrin organic frameworks are developed. Noted that the integration of {ε-PMo8VMo4VIO40Zn4} cluster and metalloporphyrin endows these polyoxometalate-metalloporphyrin organic frameworks greatly advantages in terms of electron collecting and donating, electron migration and electrocatalytic active component in the CO2 reduction reaction. Thus-obtained catalysts finally present excellent performances and the mechanisms of catalysis processes are discussed and revealed by density functional theory calculations. Most importantly, Co-PMOF exhibits remarkable faradaic efficiency ( > 94%) over a wide potential range (−0.8 to −1.0 V). Its best faradaic efficiency can reach up to 99% (highest in reported metal-organic frameworks) and it exhibits a high turnover frequency of 1656 h−1 and excellent catalysis stability ( > 36 h).

“…[68] From this point of view, the metal-organic frameworks (MOFs) can be regarded as the combination of polymerization and introduction of ion-ion interactions, leading to insoluble polymeric metal-organic networks. [69][70][71] However, such materials often are involving the redox reaction of both metals and organic components and hence will not be further discussed here.…”

Organic batteries have attracted a lot of attention due to the advantages of flexibility, light weight, vast resources, low cost, recyclability, and ease to be functionalized through molecular design. The biggest difference between organic materials and inorganic materials is the relatively weak intermolecular interactions in organic materials but strong covalent or ionic bonds in inorganic materials, which is the inherent reason of their different physiochemical and electrochemical characteristics. Therefore, the relatively weak intermolecular interactions can indisputably affect the electrochemical performance of organic batteries significantly. Herein, the intermolecular interactions that are closely related to organic redox-active materials and unique in organic batteries are summarized into three parts: 1) between neighbor active molecules, 2) between active molecules and the conduction additives, and 3) between active molecules and the binders. We hope this short review can give a distinct viewpoint for better understanding the internal reasons of high-performance batteries and stimulate the deep studies of relatively weak intermolecular interactions for strengthening the performance of organic batteries.

Summary Polyoxometalates could be viewed as the molecular counterpart of the metal oxides, which are essential ingredients for various energy conversion and storage applications. In this manuscript, we review the progress of engineering functional polyoxometalates toward energy applications, focusing on, but not limited to, polyoxotitanate, polyoxotungstate, and polyoxomolybdate. These polyoxometalates are considered to be promising candidates for dye‐sensitized solar cell, perovskite solar cell, lithium‐ion battery, lithium‐sulfur battery, supercapacitor, and water‐splitting system. We believe advanced energy devices with better performance could be derived from further engineering the polyoxometalates owing to their molecular design flexibility.
