“…In sulfur 2p HR (high resolution) spectra (Figure c), the deconvoluted peaks at 162.1 and 163.5 eV represent the occurrence of Zn–S and C–S, respectively. In Figure d, HR zinc 2p spectra consist of two peaks at 1022.2 and 1045.3 eV, corresponding to 2p 3/2 and 2p 1/2 spin–orbital splitting, respectively. , The splitting consists of 23.1 eV energy, representing the 2 + oxidation state of Zn. , The deconvoluted peaks at 284.8, 286.0, and 288.5 eV in the HR carbon 1s spectra (Figure e) represent the existence of C–C, C–O/C–S, and O–CO, respectively. In Figure f, the oxygen 1s spectra are deconvoluted into two peaks at 531.7 and 532.8 eV, which belong to O–CO and Zn–O, respectively.…”

Metal−organic frameworks (MOFs) are an emerging material with a high specific surface area, desired morphology, and tunable pore size. However, MOFs suffer due to low electrical conductivity. Transition-metal sulfides are excellent supercapacitor materials because of their large storage capacity and electrical conductivity. To preserve a high surface area and obtain high electrical conductivity, Zn-MOF is directly grown on Ni-foam, and its surface is modified through various sulfurizing agents. The asfabricated Zn-MOF on Ni-foam exhibits a vertically oriented triangular rod-like morphology. Banana blossom, fiber, and rod-like morphologies are obtained due to the surface etching and surface sulfurization process by sulfurizing agents thioacetamide (TAA), sulfur (S), and thiourea (TU), respectively. The role of iR compensation in cyclic voltammetry analysis with higher mass-loading electrodes is established. The variations in its charge storage mechanism and charge-transfer kinetics corresponding to various sulfurizing agents are examined. Compared to other commonly used sulfurizing agents, TAA-assisted surface-sulfurized Zn-MOF provided excellent charge storage performance. It exhibits a maximum areal capacity of 4484 mC cm −2 (specific capacity of 747.3 C g −1 ) at a current density of 10 mA cm −2 . The asfabricated aqueous hybrid supercapacitor device exhibits a maximum specific energy of 77.8 W h kg −1 at a specific power of 0.73 kW kg −1 , even with a higher mass loading of 12.2 mg. The role and importance of mass loading are described by using an expanded Ragone plot.

Aerosol‐assisted chemical vapor deposition (AACVD) was used to deposit highly transparent and conductive titanium or fluorine‐doped and titanium‐fluorine co‐doped ZnO thin films on glass substrate at 450 oC. All films were characterized by X‐ray photoelectron spectroscopy (XPS), X‐ray diffraction (XRD), UV‐Vis spectroscopy, scanning electron spectroscopy (SEM), and four‐point probe. The films were 600‐680 nm thick, crystalline, and highly transparent (80‐87%). The co‐doped film consisted of 0.70 at.% titanium and 1 at.% fluorine, and displayed a charger carrier mobility, charge carrier concentration, and a minimum resistivity of 8.4 cm2 V‐1 s‐1, 3.97 x 1020 cm‐3, and 1.69 x 10‐3 Ω cm, respectively. A band gap of 3.6 eV was observed for the co‐doped film. Compared to the undoped and singly doped films, the co‐doped film displayed a notably higher structure morphology (more homogenous grains with well‐defined boundaries) suitable for transparent conducting oxide applications.
