“…At higher temperatures however, additional decomposition steps take place. 33 The third step of weight loss ( M 3 ) taking place from 233 to 376 °C indicates the weight loss of 1.79% for CuO–ZnO, which is attributed to the complete conversion to the crystalline form. Figure 2b shows typical N 2 adsorption–desorption isotherms of CuO(50%)–ZnO(50%) NCs.…”

Heterostructural CuO–ZnO Nanocomposites: A Highly Selective Chemical and Electrochemical NO₂ Sensor

et al. 2019

A simple one-step chemical method is employed for the successful synthesis of CuO(50%)–ZnO(50%) nanocomposites (NCs) and investigation of their gas sensing properties. The X-ray diffraction studies revealed that these CuO–ZnO NCs display a hexagonal wurtzite-type crystal structure. The average width of 50–100 nm and length of 200–600 nm of the NCs were confirmed by transmission electron microscopic images, and the 1:1 proportion of Cu and Zn composition was confirmed by energy-dispersive spectra, i.e., CuO(50%)–ZnO(50%) NC studies. The CuO(50%)–ZnO(50%) NCs exhibit superior gas sensing performance with outstanding selectivity toward NO2 gas at a working temperature of 200 °C. Moreover, these NCs were used for the indirect evaluation of NO2 via electrochemical detection of NO2– (as NO2 converts into NO2– once it reacts with moisture, resulting into acid rain, i.e., indirect evaluation of NO2). As compared with other known modified electrodes, CuO(50%)–ZnO(50%) NCs show an apparent oxidation of NO2– with a larger peak current for a wider linear range of nitrite concentration from 20 to 100 mM. We thus demonstrate that the as-synthesized CuO(50%)–ZnO(50%) NCs act as a promising low-cost NO2 sensor and further confirm their potential toward tunable gas sensors (electrochemical and solid state) (Scheme 1).

“…The CuO(50%)–ZnO(50%) NCs consisting of the characteristic flakelike NCs of width about 50–100 nm and length of a few micrometers are in good agreement with earlier reports. 33 TEM images show that the surface of ZnO is covered by CuO nanoparticles (NPs). Also, the exposed ZnO flakes are shown in the TEM image (Figure 1c).…”

“…[7][8][9] On the other hand, transition metal oxides (TMOs) as electrode materials have been widely explored because of their high theoretical specic capacitances, abundance, high voltage window in aqueous electrolyte, environmental friendliness, and low-cost of electrode material for pseudocapacitors. [10][11][12][13][14] Unfortunately, most TMOs suffer from their weak electrical conductivities resulting in poor electrochemical performance. 15,16 To circumvent this issue, researchers developed mixed TMOs with different metal cations demonstrating the synergic effect, reversible capacity, structural stability, more active reaction sites for redox (faradaic) reaction, and higher electrical conductivity compared to TMOs.…”

“…Indeed, given the environmental and material constraints, alternative anode materials for battery research should be developed to identify material choices that exhibit high energy density at low operating voltage while providing outstanding stability and safety. So far, various metal oxides, transition metal sulfides (MoS 2 , FeS 2 , Co 9 S 8 , VS 2 ), carbon-based materials and Sn-based materials have been investigated as anode materials [ 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ].…”

Electrochemical Performance of Orthorhombic CsPbI3 Perovskite in Li-Ion Batteries

et al. 2021

A facile solution process was employed to prepare CsPbI3 as an anode material for Li-ion batteries. Rietveld refinement of the X-ray data confirms the orthorhombic phase of CsPbI3 at room temperature. As obtained from bond valence calculations, strained bonds between Pb and I are identified within PbI6 octahedral units. Morphological study shows that the as-prepared δ-CsPbI3 forms a nanorod-like structure. The XPS analysis confirm the presence of Cs (3d, 4d), Pb (4d, 4f, 5d) and I (3p,3d, 4d). The lithiation process involves both intercalation and conversion reactions, as confirmed by cyclic voltammetry (CV) and first-principles calculations. Impedance spectroscopy coupled with the distribution function of relaxation times identifies charge transfer processes due to Li metal foil and anode/electrolyte interfaces. An initial discharge capacity of 151 mAhg−1 is found to continuously increase to reach a maximum of ~275 mAhg−1 at 65 cycles, while it drops to ~240 mAhg−1 at 75 cycles and then slowly decreases to 235 mAhg−1 at 100 cycles. Considering the performance and structural integrity during electrochemical performance, δ-CsPbI3 is a promising material for future Li-ion battery (LIB) application.
