Summary: Galvanic replacement synthesis is a method involving oxidation and dissolution of atoms from a substrate while reducing and depositing a salt precursor on the substrate. It offers advantages over conventional electrosynthesis due to the use of micro/nanostructured materials, which increase surface area and enable intimate mixing with the precursor. The synthesis enables control over the growth pattern of deposited atoms on the substrate, leading to diverse nanomaterials with controllable compositions and shapes.

Summary: Galvanic replacement synthesis involves the oxidation and dissolution of atoms from a substrate while reducing and depositing a salt precursor with a higher reduction potential on the substrate. Micro/nanostructured materials can be mixed with the salt precursor in a solution phase, increasing the surface area and allowing for controlled growth patterns of the deposited material. This synthesis method has been successfully applied to various substrates, resulting in diverse nanomaterials with controllable compositions and morphologies.

Summary: Mixed transition metal oxides are promising electrode materials for electrochemical energy storage and conversion. The synthesis of these materials with tailored composition, crystal structure, and morphology is crucial for optimizing their properties. This study reports on the room-temperature electrodeposition of a ternary oxide, ZnMnO3, using earth-abundant metals. The epitaxial growth of ZnMnO3 on ZnO nanowires results in a 2-dimensional morphology and shows promise for the direct growth of other mixed transition metal oxides on conductive substrates.

Summary: In this study, a feasible and eco-friendly electrode material for supercapacitor application was developed by synthesizing different morphological structures of tungsten oxide nanostructures (WO3NSs). The electrochemical activity of WO3-NSs was evaluated by employing concentrated acids in the synthesis process. The WO3-NSs exhibited different morphologies such as hexagonal-shaped nanosheets, one-dimensional nanorods, and heterogeneous non-uniform agglomerated nanosheets as observed by FE-SEM. The optimized WO3NRs were further characterized using TEM and XPS for detailed morphological, structural, elemental composition, and electronic states analysis. The electrochemical properties of the WO3-NSs were examined in 1 M KOH electrolyte, and the M-WO3-NF electrode showed high specific capacity, gravimetric capacitance, energy density, power density, and Columbic efficiency, as well as excellent capacitive retention over 5000 cycles.

Summary: In this study, a composite electrode composed of Ti/TiH2/beta-PbO2_Mn3O4@C was fabricated and investigated for zinc electrowinning. The composite electrode exhibited low overpotential, Tafel slope, icorr, and high voltage stability, outperforming most reported Ti-based PbO2 electrode materials. The excellent catalytic activity can be attributed to the low resistance and porous interlayer of TiH2 nanosheets, as well as the addition of Mn3O4@C micro-flakes to the active layer.
