Summary: Transition metal sulfides (TMS) are promising electrode materials for supercapacitor applications. To overcome the deficiency of individual metal sulfides, the combination of pseudocapacitive transition metals with conductive carbon material can be a plausible solution. In this work, flower-like Ni3S2/CoS2/MoS2 (NCMS) and Ni3S2/CoS2/MoS2-GQDs (NCMS-G) structures were fabricated directly on Ni foam using a hydrothermal synthesis method. The NCMS-G-2.5 electrode showed high specific capacitance, excellent rate capability, and good cycling stability. Furthermore, an assembled NCMS-G-2.5//rGO asymmetric supercapacitor (ASC) device exhibited excellent energy density and superior cycling performance. The interactions between Ni3S2/CoS2/MoS2 and carbon based nanostructure GQDs were investigated using Density Functional Theory (DFT) simulations, revealing enhanced electronic states near Fermi level and improved conductivity for the hybrid structure. The fabricated 3D flower NCMS-G-2.5 has potential prospects for developing advanced and high-performance energy storage devices.

Summary: Self-assembly relies on the ability of smaller entities to arrange into organized systems, with the design of the media playing a crucial role. The media determines the self-assembly pathway and can control the wrapping process of supramolecular homo-aggregates by a different crystal lattice component. This reverse coating process is controlled by the media composition and could lead to the construction of hierarchical supramolecular structures.

Summary: Seeking earth-abundant and high-performance cocatalysts is crucial for efficient artificial photoreduction of CO2 to solar fuels. Six Ni species were evaluated as noble-metal-free cocatalysts for photocatalytic CO2 reduction. Results showed that NiS and Ni2P accelerated H2 evolution and decreased the selectivity for CO2 reduction, while Ni3C and Ni3N promoted CO2-to-CO conversion and inhibited proton reduction. The best-performing TiO2-Ni3N achieved a high CO production rate of 49.6 mu mol g(cat)(-1) h(-1) and a selectivity of 94.1% for CO2 reduction.
