## Description

- description: Global environmental challenges and energy crises have driven researchers
    to develop multifunctional and highly efficient nanomaterials. This study presents
    dual-functional NiMoO4 (NMO)/NiO hierarchical microspheres that can serve as supercapacitors
    and photocatalysts prepared using a microwave-assisted hydrothermal method. The
    α- and β-phase contents of NMO can be regulated by controlling the post-annealing
    temperature and pH value of the precursor solution. The as-prepared NMO/NiO nanocomposites
    exhibited dual Faradaic redox reactions attributed to NMO and NiO, leading to
    remarkable supercapacitor performance. In addition, the constructed heterojunction
    between NMO and NiO also improved charge separation, leading to excellent photocatalytic
    capability. Based on the results, NMO with a higher β-phase content showed better
    supercapacitive and photocatalytic performance owing to its higher conductivity.
    The optimal NMO/NiO composite displayed a specific capacitance of 943 F g− 1 at
    1 A/g and excellent cycling stability, with 83.1 % retention at 5 A/g after 4000
    cycles. Additionally, it demonstrated an outstanding photocatalytic capability
    for the degradation of methylene blue (MB), achieving a rate constant of (0.0113
    min− 1)
