Subsequently, the reversible capacity was maintained above 100 mAh g −1 beyond 50 cycles for the 90PbO/10C nanocomposite electrodes, which is higher than the values reported by Martos et al 9 for lead oxide powder anodes in lithium-ion rechargeable batteries. This shows that PbO-carbon nanocomposites are promising as anode materials for Li-ion batteries.…”

A new approach has been used to prepare nanostructured lead oxide-carbon ͑PbO-C͒ composites via the spray pyrolysis technique. In this study, the electrochemical performance of the PbO-carbon nanocomposites as anode materials for lithium-ion rechargeable batteries was investigated. The prepared powders consist of fine nanocrystalline PbO homogeneously distributed within an amorphous carbon matrix with highly developed surface area. The estimated average crystal sizes of these nanocomposites from X-ray diffraction ͑XRD͒ patterns are in the range of 26-102 nm. The combination of spray technology and carbon addition increased the specific surface area ͑above 6 m 2 g −1 ͒ and the conductivity of PbO, improved the specific capacity, and maintained cycle life with a reversible capacity above 100 mAh g −1 beyond 50 cycles. The increase in capacity retention for PbO-carbon compared to that of pure PbO was due to the presence of a conductive and highly developed carbon matrix that can absorb large volume changes during the alloying/dealloying of lead with lithium over the 1.50 to 0.01 V potential range, which yields Li x Pb alloys ͑0 Ͻ x Ͻ 4.5͒.

“…Lead oxide, which is one of the basic lead compounds, exists in different stoichiometric forms depending on the lead-to-oxygen ratio, e.g., PbO, PbO 2 , Pb 2 O 3 , Pb 3 O 4 , and Pb 9 O 12 . Among these, PbO, a direct band gap semiconductor having two polymorphs aPbO and b-PbO with band gap energies of 2.2 and 2.5 eV, respectively, has attracted a greater focus due its exceptional mechanical, electronic, and optical properties (Karami and Alipour 2009;Lafront et al 2010;Martos et al 2001;Xi et al 2004). Another important lead compound is PbS.…”

In this study, nano-crystalline lead sulfide (PbS) and lead oxide (PbO) were synthesized using hassle-free and cost-effective chemical route. Lead oxalate (PbC 2 O 4 ) precursor was thermally decomposed to obtain the nanocrystalline PbO, while PbS nanoparticles were synthesized by microwave irradiation on a mixture of PbC 2 O 4 precursor and sodium thiosulfate. Resulting materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier transform infrared spectroscopy, ultraviolet-visible (UV-Vis) spectrophotometry, differential scanning calorimetry (DSC), and thermogravimetric analysis (TGA). XRD confirmed the tetragonal structure for PbO and face-centered cubic for PbS with average crystallite sizes varying from 20 to 30 nm for both materials. From UV-Vis spectra, direct band gap energies were calculated to be 2.51 and 2.23 eV for PbO and PbS, respectively. Various decomposition stages during heat treatment of PbO and PbS, as revealed by TGA/DSC, are discussed in detail.

“…Other applications are in the field of lead-containing high temperature superconducting films [11,12] and high refractive index materials [13]. Lead monoxide films have also been used as an anodic material for lithium secondary batteries [14]. Being a strong oxidizing agent, lead dioxide has been used as an oxidant [15].…”

“…Lead oxide thin films have been laid on by both physical and chemical deposition methods. Physical methods reported in the literature include pulsed laser-assisted deposition [17], dc and rf magnetron sputtering [18], while chemical methods include spray pyrolysis [13,14] and electro deposition [19]. Amongst the chemical methods used to fabricate lead oxide thin film, spray pyrolysis method is simple, inexpensive, and capable of producing films on large scale area for industrial applications.…”

Thin films of lead oxide were synthesized by cost effective spray pyrolysis technique at different substrate temperatures on glass substrates. Effect of substrate temperature on the growth mechanism and physical properties of the films was investigated. All the films were polycrystalline in nature with tetragonal structure corresponding to α-PbO. The films coated at 225°C and 275°C were (1 0 1) oriented, while the films deposited at 325°C and 375°C were (0 0 2) oriented. Above 375°C, the pure tetragonal nature deteriorated and the peaks corresponding to orthorhombic phase were observed. The band gap value was found to be in the range of 2.3 to 2.62 eV. All the films had a resistivity of the order of 10 3 ohm-cm. A minimum resistivity of 0.0191 × 10 3 ohm-cm was obtained for the film coated at 325°C. The activation energy increased with increase in substrate temperature.
