Summary: By loading TiO2 nanoparticles onto MnO2 nanosheets to form a nanostructured heterojunction, the separation/transfer efficiency of photocarriers and the solar absorptivity were improved, enhancing the solar energy conversion efficiency. The enhanced carrier transfer efficiency and visible absorption can be attributed to the 2D network of MnO2 and narrowed bandgap, leading to an increased H-2 production rate and improved photocatalytic properties.

Summary: A highly electroactive vanadium carbide MXene, V2CTx @C, was synthesized in a carbon matrix with the assistance of metal organic frameworks (MOFs). The morphological changes in the stacked nanosheets resulted in the formation of exfoliated carbon enriched V2CTx nanodiscs, leading to improved specific surface area, electronic conductivity, and electrode/electrolyte interfacial contact area. The V2CTx @C electrode exhibited high specific capacitance, remarkable rate performance, and outstanding cycling stability. The strategy of structural engineering in MXene based electrode materials provides potential for next generation energy storage devices.

Summary: One-dimensional MnO2 nanorods are evenly distributed on two-dimensional g-C3N4/rGO nanosheets through a simple hydrothermal approach. The prepared samples are characterized in terms of structure, functional groups, morphologies, elemental analyses, and surface area. The MnO2/g-C3N4/rGO material exhibits superior electrochemical performance due to its high surface area and the synergistic effects of MnO2 and g-C3N4/rGO, making it an excellent option for high-performance supercapacitors. In addition, a pouch-type supercapattery device assembled with MnO2/g-C3N4/rGO and activated carbon electrodes achieves a high specific capacitance, excellent capacitance retention, and a high energy density.
