“…The values show that rGO-SnS nanohybrid possesses the highest crystallinity followed by rGO-CuS and rGO-ZnS, which is in accordance with the increase in peak broadness from rGO-SnS → rGO-CuS → rGO-ZnS. The estimated interplanar spacing, lattice parameters, average crystallite size, and % crystallinity of the synthesized nanohybrid materials are summarized in Table T3. ,, …”

“…The peaks at 195 and 219 cm −1 correspond to the A g mode of SnS and appear due to the vibrations between Sn and S atoms, whereas the peak at 164 cm −1 is attributed to the B 3g optical mode. 43,44 Also, from the Raman spectra of all the nanohybrid materials, it is observed that the peaks corresponding to the metal-sulfide components are less intense as compared to the D and G bands of rGO. As mentioned above, the D and G bands result from the presence of defects and sp 2 carbon vibrations, respectively.…”

Hybrid material-based resistive random-access memories (ReRAM) have gained immense popularity as data storage devices owing to their high scalability, easy processability, and cost-effectiveness. Herein, we report the resistive switching (RS) performances of various nanohybrid materials, consisting of metal-sulfide (ZnS, CuS, and SnS)-grafted reduced graphene oxide (rGO), by embedding into a thin polymeric layer. An active layer with a sandwich electrode configuration (ITO/nanohybrid-PMMA composites/Al) is realized for electrical studies. Additionally, the RS phenomena are modulated through precisely varying the concentration of nanohybrid-polymer composite fillers. The electrical studies display the bipolar-resistive switching properties along with an extremely low V SET/V RESET of ∼−0.44 ± 0.10/+0.50 ± 0.10 V. Also, a very low write/erase power consumption (P SET/P RESET) of ∼1.02 × 10–5 / 1.18 × 10–5 Wcm–2 is obtained for the CuS-grafted rGO nanohybrid. Furthermore, a current ON/OFF (I ON/I OFF) ratio of ∼103–104 is obtained for all the fabricated devices, which lowers the level of misreading in the nanohybrid devices. All the devices display excellent RS properties, especially low operating voltage, high reliability, and high persistency for optimum loading of nanofillers concentration ranging from 0.3 to 0.5 wt %. The interfacial synergistic effect coupled with trapping and detrapping of charge carriers is considered responsible for the observed resistive switching behavior.

Recent Progress on Titanium Dioxide Nanomaterials for Photocatalytic Applications

Environmental and energy problems have drawn much attention owing to rapid population growth and accelerated economic development. For instance, photocatalysis, "a green technology", plays an important role in solar-energy conversion owing to its potential to solve energy and environmental problems. Recently, many efforts have been devoted to improving visible-light photocatalytic activity by using titanium dioxide as a photocatalyst as a result of its wide range of applications in the energy and environment fields. However, fast charge recombination and an absorption edge in the UV range limit the photocatalytic efficiency of TiO under visible-light irradiation. Many investigations have been undertaken to overcome the limitations of TiO and, therefore, to enhance its photocatalytic activity under visible light. The present literature review focuses on different strategies used to promote the separation efficiency of electron-hole pairs and to shift the absorption edge of TiO to the visible region. Current synthesis techniques used to elaborate several nanostructures of TiO -based materials, recent progress in enhancing visible photocatalytic activity, and different photocatalysis applications will be discussed. On the basis of the studies reported in the literature, we believe that this review will help in the development of new strategies to improve the visible-light photocatalytic performance of TiO -based materials further.

“…33 Besides, costly additives and surfactants are oen used for geometry control, and large-scale material preparation is thus challenging. [34][35][36] Electrodeposition is a simple alternative approach of nanofabrication which can be dated back to 1987 in the pioneering work of Martin et al 37 Yet, a template is oen required for the synthesis and plating three-dimensional intricate structures at the nanometric scale remains problematic. Though the coprecipitation approach has recently allowed precise control of the formation of complex micrometer-scale shapes with amazing beauty, downsizing the shape to the nanometer scale is yet impossible.…”
