In this paper we report Cu doping induced modifications in the structural, photoluminescence and gas sensing behaviour of SnO2 nanoparticles. Our results show that crystallinity is reduced upon doping. The PL emissions observed visible region are attributed to defect levels arising due oxygen vacancies. 1.5 at% Cu-doped shows selective high response (∼80%) 50 ppm concentration formaldehyde over methanol, ethanol, propanol-2-ol, acetone n-butylacetate at 200 °C. mechanism has been explained...
Here, we demonstrated the formation of active sites O<sub>2</sub><sup>−</sup> and O<sup>−</sup> on surface nanocube In<sub>2</sub>O<sub>3</sub>@RGO heterostructure, gas sensing mechanisms fluctuations in potential barrier height before after insertion acetone formaldehyde.
We report the H2 and LPG gas sensing behavior of RGO/SnO2 QDs synthesized by a surfactant assisted hydrothermal method. The QD based sensor shows high response ∼89.3% to ∼92.4% for 500 ppm test concentration at operating temperatures 200 °C 250 °C, respectively. Further, good selectivity in presence other interfering gases such as ammonia, chloroform, toluene, benzene, acetone, n-butylacetate, acetic acid formic acid. observed that is 29.8 times higher than whereas 17.8 Long-term analyses...
Recent advancements in thermoelectric (TE) materials have opened up new possibilities for efficient waste heat recovery and renewable energy generation. The latest innovations materials, including novel composites, nanostructured systems, low-dimensional significantly enhanced the performance, thereby enabling higher efficiency conversion. Integration strategies, such as incorporating modules into industrial exhaust streams, automotive exhausts, solar thermal collectors, demonstrated...
Herein, this work elucidates the synthesis of Pd-MoS2 catalyst for application in methanol-mediated overall water splitting. The scanning electron microscope (SEM) and transmission (TEM) pictures offer an exciting nanostructured shape Pd-MoS2, depicting a high surface area. Further, high-resolution TEM (HRTEM) confirm lattice plane (100), spacing (0.26 nm), hexagonal crystal structure Pd-MoS2. Moreover, high-angle annular dark-field (HAADF) images related color maps disclose Mo, S, Pd...
Ionic active site formation, VOC interactions with depletion-region modulation, and the outstanding selectivity of a SnS<sub>2</sub> NLS sensor were demonstrated in this study.
Here, we demonstrated a unique symmetric supercapacitor (SSC) device architecture based on reduced graphene oxide (RGO) and nitrogen-doped RGO (N-RGO) electrodes.
