| Electrochemical Oxidation of Methanol at Pt/Au Modified | To find a novel and a cheap anode for direct methanol fuel cell that resists the poisoning by carbon monoxide produced inside the cell Methods/Statistical Analysis: We prepare triplet electrode by using electrodeposition technique in nano-scale to improve the overall electro-catalytic properties of anode towards electrochemical oxidation of methanol Findings: The prepared nano-anode is better than the traditional electrode Pt/Au because the triplet anode Pt/Au/Sn give higher current density in low over potential Application/Improvements: There exist many applications of this triplet nano-anode in portable devices, cars, vehicles, airplanes and space shuttles |
| Controlled Hydrothermal Synthesis of NanoMoO2 as Anode for Lithium Ion Battery | Nano-MoO2, with different allotropic forms is synthesized through a reduction reaction of molybdenum trioxide in aqueous solutions using ethylene glycol The structure and morphology characterizations are carried out by XRD, SEM, and Raman The XRD and SEM data indicate the as-prepared samples present a single and homogeneous phase MoO2 with monocline symmetry Findings/application: The optical properties of the as-synthesized samples are investigated by photoluminescence Cyclic voltammetric characterization of MoO2 films has revealed reversible redox behavior with charge–discharge cycling which corresponds to the reversible lithium intercalation/deintercalation The electrochemical properties study of the MoO2 has showed that the monoclinic MoO2 has a good stability and a nice reversibility, an indicator that the molybdenum dioxide is most suitable for application in lithium-ion batteries (LIBs) |
| Enhanced solar photocatalytic performance of Cu-doped nanosized ZnO | We report the controlled synthesis of nanostructured undoped and Cu-doped ZnO by a simple one-step hydrothermal treatment, characterized by X-ray diffraction (XRD), scanning electronic microscopy (SEM), Raman spectroscopy and photoluminescence (PL) XRD results showed that all samples present a hexagonal wurtzite structure The SEM micrographs revealed that the particles have a hexagonal shape and a uniform size distribution Optical band gap was found to vary with Cu content The photoluminescence spectra indicate that the introduction of Cu into pure nano-ZnO causes a decrease in surface defects, such as oxygen and zinc vacancy In fact, this study shows that the intensity of the PL decreases initially when the concentration of Cu doping increases (greater than 1%) Whereas, when the concentration of the Cu doping rate is 05% the PL intensity increases The result indicates that doping with Cu with a suitable concentration can effectively inhibit the recombination of the free charge carriers The as-synthesized nanostructures were used as photocatalysts for the degradation of methyl orange (MO) under solar irradiation The PL and photocatalysis results reveal that the highest photocatalytic activity is obtained with the 1% Cu-doped ZnO photocatalyst In fact, this study shows that the photodegradation follows firstorder kinetics Therefore, in the absence of ZnO photocatalyst a low kinetic rate constant of 5634104- min1 is estimated while the introduction of undoped or 1% Cu-doped ZnO increases the kinetic constant by approximately 9 and 20 times, respectively |
| Pulsating flow of nanofluid with shape effects of particles on the cooling efficiency of photovoltaic panel and performance estimations with machine learning approaches | The present work proposes a new cooling system for thermal management and cooling of photovoltaic (PV) systems Pulsating flow with multiple jet impingement is considered by using different fluid types Hybrid nanofluid and alumina–water nanofluid having cylindrical ans spherical shaped nanoparticles are used as the cooling medium The study is conducted by using finite volume method for various values of pulsating amplitude (between 0 and 1), Strouhal number (between 001 and 1), solid volume fraction of nanoparticles (between 0 and 2%) and slot number of the impinging jet (between 1 and 13) It is observed that pulsating amplitude is more effective on the cooling performance enhancement as compared to frequency while average Nusselt number (Nu) rises by about 635% while temperature drop of 216 ◦C can be achieved when pulsation amplitude is increased from 0 to 1 Nanofluid with cylindrical shaped nanoparticles and hybrid nanofluid show very similar trends while temperature drop of 26 ◦C is achieved when cooling system with nanofluid-cylinder in pulsating flow case is compared with pure-fluid in non-pulsating flow configuration When nanoparticles loading amount on the thermal improvement is compared, the most favorable cases are obtained for nanofluid-cylinder and hybrid nanofluid case The average Nu increments become 35%, 228% and 229% for nanofluid-spherical, nanofluid-cylinder and hybrid nanofluid when lowest and highest nanoparticle loading amount cases are compared Increasing the slot number in pulsating flow case significantly rises the Nu and drops the average panel surface temperature When different systems are compared pulsating nano-jets cooling system using alumina–water nanofluid with cylindrical shaped nanoparticles provides the most effective cooling system while while temperature drop of 𝛥𝑇 = 3730 ◦C is achieved at the highest amplitude and highest loading of nanoparticles in the pure fluid as compared to uncooled PV system |
| Novel composite materials H2V3O8/PEDOT:PSS as cathode for rechargeable lithium ion batteries | Owing to the high demand for electronic devices and electric vehicles, a huge effort has been directed to the exploration and development of new batteries with good cycling stability, satisfactory high specific capacity and safety In this paper,we report the designed synthesis of the vanadium oxide with mixed valence H2V3O8 and the composite H2V3O8/PEDOT:PSS using low cost and easy hydrothermal method Electrochemical activity of the vanadium oxyhydroxide H2V3O8 and the composite H2V3O8/PEDOT:PSS as cathodes materials for high performance lithium–ion batterieswasevaluated vsLi?/Li at various current ratesComparedwith pureH2V3O8, composite H2V3O8/PEDOT:PSS cathode exhibits higher specific capacity (390 mAh g-1 at 005 A g-1 whereas, an initial discharge capacity of 300 mAh g-1 is observed at 03 A g-1), more excellent rate performance and longer cycle life The composite H2V3O8/PEDOT:PSS cathode delivers excellent specific capacity of ca 390 mAh g-1 and a 975% capacity retention are achieved even after 350 cycles at current density of 005 A g-1 Higher electrochemical capacity and stability of the new composite cathode are mainly ascribed to a cooperative effect between the conductive polymer (PEDOT:PSS) with good electrical conductivity and the unique nano-sized H2V3O8 rods with short diffusion pathway for lithium ions diffusion |
| Enhanced photocatalytic properties of nano-Nb2O5 for degradation of methylene blue | Mixing the advantages of nano-Nb2O5 and reduced graphene oxide (rGO), composite systems offer great potential of exploration Herein, Nb2O5 nanoparticles (NPs) and Nb2O5 modified reduced graphene oxide (Nb2O5/rGO) urchin-like have been successfully synthesized by hydrothermal process The materials were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), Raman spectroscopy, nitrogen adsorption-desorption isotherms, and UV–vis diffuse reflectance spectroscopy The photocatalytic efficiency of the Nb2O5 NPs and Nb2O5/rGO urchin-like were evaluated with respect to the degradation of methylene blue (MB) under solar radiation It is found that the Nb2O5/rGO with porous structure and high specific surface area of ~10525 m2/g shows significantly superior photocatalytic performances for the removal of the MB dye (99% degradation after 1h illumination) than pure Nb2O5 (20% degradation after 1h illumination) The improvement in the photocatalytic properties of the composite material is mainly ascribed to a cooperative effect between the rGO with good electrical conductivity and the unique nano-porous structure of Nb2O5 with abundant catalytic active sites, superior charge transfer efficiency, and stronger oxidation property |
