“…As there are four formula units per crystallographic unit cell, the structure consists of layers of NiO octahedra at x = 0 and x = 0.5 which are separated by two intervening NbO 6 layers. However, previous studies have also demonstrated the formation of disordered rutile (P4 2 /mnm) [23] and tetragonal (P4 2 /n) [24] polymorphs. X-ray diffraction (XRD) analysis of our synthesized particles confirmed the formation of the orthorhombic NiNb 2 O 6 structure, as shown in Figure 2a.…”

Nowadays, fast charging ability of energy storage devices is essential for applications in electric vehicles and electrical power grids. The fast charging performance of batteries is enabled by highrate electrode materials. which have been realized through various methods such as nanosizing, porous structures, carboncoatings, and conductive materials-based hierarchical structures. [1] Nanosizing and porous structures can enhance the lithium-ion transport as they reduce the distance lithium ions have to diffuse in the solid electrode, and they also enlarge the contact area between the liquid electrolyte and the electrode material. [2] Carbon-coatings and conductive materials (e.g., graphene or Mxene) based hierarchical structures can enhance the electrical conductivity of the electrodes to enable higher current densities. [3] However, nanosizing and porous structures lead to a reduction of the specific volumetric capacity, while composites with carbon-based conductive materials require the electrode to discharge down to 0.01 V resulting in lithium dendrite formation under high current densities. [4][5][6] The formation of nanostructures can even result in a reduced electrochemical performance at high C rates as compared to their bulk materials due to possible morphology change, nanostructure collapse, and higher first-cycle capacity loss. [7][8][9] Furthermore, the fabrication of these delicate nano-architectures, porous structures, and composites usually require harsh synthesis environments, expensive reactants, and multiple synthesis steps, which results in a complex and expensive synthesis process. Additionally, such synthesis methods often provide either relatively low yields or significant amounts of chemical waste.Recent studies increasingly focus on the development of electrode materials with an intrinsic high-rate performance by combining the advantages of exhibiting 1) a suitable host structure for fast lithium-ion intercalation, 2) a lower bandgap to enhance the electrical conductivity, and 3) a higher working voltage to avoid lithium dendrite formation. Titanium-based oxides, such as Li 4 Ti 5 O 12 and anatase TiO 2 , are well known as interesting electrode materials, while they exhibit working voltages of 1.55 and 1.8 V, [10,11] respectively, preventing lithium plating. However, in order to obtain high rate performance,

“…For the Ni 2p 3/2 peak, three components were observed. The largest contribution comes from a component at 856.7 eV, and is thought to be related to the 2+ oxidation state of nickel, [31][32][33] with a satellite peak at 861.2 eV. A minor component is also observed at 852.1 eV, which is thought to be related to metallic nickel.…”

The presence of Ni3 + on the surface of nanocomposites may arise from the surface oxidation of Ni (OH) 2 42 – 45 . Figure 4 e depicts the Cu2p high-resolution deconvoluted spectra of the Cu/Ni/TiO 2 /MWCNTs nanocomposites have major two peaks at 933.9 and 953.8 eV due to Cu2p 3/2 and Cu2p 1/2 , respectively.…”

“…Simultaneously, photocatalysis surface adsorbed O 2 was reduced to O 2 − by e − , which then converted into more active hydroxyl radicals. Hence, the active reactive species effectively attacked persistently to the target organic pollutants and are enhanced the degradation efficiencies 42 – 47 . However, the lower and higher concentration of photocatalysis degradation efficiencies was decreased due to maybe the presence of less or more reactive species.…”

In this manuscript, “Get two mangoes with one stone” strategy was used to study the electrochemical detection and photocatalytic mineralization of furaltadone (FLT) drug using Cu/Ni/TiO2/MWCNTs nanocomposites for the first time. The bi-functional nanocomposites were synthesized through a hydrothermal synthesis technique. The successfully synthesized nanocomposites were analyzed by various analytical techniques. The Cu/Ni/TiO2/MWCNTs nanocomposites decorated screen-printed carbon electrode (SPCE) exhibit a good electrocatalytic ability towards detection of FLT. Moreover, the electrocatalytic detection of FLT based on the nanocomposites decorated SPCE have high stability, lower detection limit, and excellent sensitivity of 0.0949 μM and 1.9288 μA μM−1 cm−2, respectively. In addition, the nanocomposites decorated SPCE electrodes performed in real samples, such as river water and tap water, the satisfactory results were observed. As UV–Visible spectroscopy revealed that the Cu/Ni/TiO2/MWCNTs nanocomposites had an excellent photocatalytic ability for degradation of FLT drug. The higher degradation efficiency of 75% was achieved within 45 min under irradiation of visible light. In addition, after the degradation process various intermediates are produced which is confirmed by GC–MS analysis. The excellent photocatalytic ability was improved to the dopant ions and restrictions of electron–hole pair.
