Summary: In this study, the effect of transition metal oxide -(Co3O4/Fe3O4) nanoparticles on the electrochemical energy storage performance of ZnO-GO-PANI nanocomposites was compared. The results showed that the quaternary nanoarchitectonics composites of -Co3O4-ZnO-GO-PANI (S1) and -Fe3O4-ZnOGO-PANI (S2) exhibited layered fibrous structure and formed a porous and mesh-like network. Electrochemical analyses revealed that S1 had better performance with a higher specific capacitance (246.33 F/g) compared to S2 (110.17 F/g) due to the higher reduction potential of Co. The enhanced ionic intercalation and improved electrical conductivity of S1 contributed to its superior energy storage performance. Therefore, the -Co3O4-ZnO-GO-PANI nanoarchitectonics composite can be a promising electrode material for high-performance energy storage devices.

Summary: Transition metal phosphides and phosphates are emerging as promising electrode materials for energy storage devices. A new trimetallic Zn-Co-Ga phosphate electrode material shows significantly higher specific capacity than mono- or bimetallic phosphates, along with superior conductivity and coulombic efficiency. Density functional theory calculations suggest that the enhanced metallic conductivity of ZCGP is due to modified exchange splitting from the 3d-orbitals of Co atoms in the presence of Zn and Ga. An engineered hybrid supercapacitor device using ZCGP//rGO demonstrates high energy and power densities, making it a potential candidate for energy storage applications.

Summary: Metal-organic frameworks (MOFs) are well-investigated nanomaterials with high surface area and customizable porosity. They are used as templates to achieve desired properties in MOF-based nanomaterials for energy storage systems. MOF-derived materials such as porous carbon, metal/metal oxide, and metal/metal oxide@C have shown excellent performance in electrochemical energy storage devices. However, there is a lack of exploration in the derivation of MOFs into chalcogenide compounds like sulfides, selenides, and tellurides. This review discusses the development and challenges of MOFs in obtaining MOF-derived transition metal chalcogenides (TMCs) and explores their applications in batteries, supercapacitors, and electrocatalysis.

Summary: The rational design of highly oriented and integrated heterostructures based on metal-organic framework (MOF)-derived carbon containing n-type metal chalcogenides (Zn-In-S/C) polyhedron and p-type metal oxide (CuO) nanowires was proposed. The p-type CuO nanowires were used as a stable scaffold to grow MOF-derived n-type Zn-In-S/C. The controlled and in situ fabricated Zn-In-S/C@CuO heterostructures provided a p-n heterojunction which enhanced the charge transfer, hence providing an improved overall electrochemical performance over its MOF and bare CuO counterpart. Coupled with density functional theory (DFT) calculations, the enhancement in the conductivity of the heterostructure was further verified. The symmetric supercapacitor device delivered an energy density of 7 Wh kg-1 at a power density of 4 kW kg-1. Overall, the theoretical and experimental investigation of the oriented in situ grown Zn-In-S/C@CuO heterojunction with better cycling stability and electrochemical activity could be a useful asset for energy storage devices.
