Well-crystallized iron(III)-doped TiO2 nanopowders with controlled Fe3+ doping concentration and uniform dopant distribution, have been synthesized plasma oxidative pyrolysis. The photocatalytic reactivity of the a mean particle size 50-70 nm was quantified in terms degradation rates methyl orange (MO) aqueous suspension under UV (mainly 365 316 nm) visible light irradiation 405 436 nm). photodecomposition MO over followed distinct two-stage pseudo first order kinetics. Interestingly,...
Iron(III)-doped TiO2 nanopowders, with controlled iron to titanium atomic ratios (RFe/Ti) ranging from nominal 0 20%, were synthesized using oxidative pyrolysis of liquid-feed metallorganic precursors in a radiation-frequency (RF) thermal plasma. The valence doped the TiO2, phase formation, defect structures, band gaps, and magnetic properties resultant nanopowders systematically investigated Mössbauer spectroscopy, XRD, Raman TEM/HRTEM, UV−vis measurements properties. was trivalent (3+)...
Transition metal compounds are one of the highly efficient types catalyst for improving reaction kinetics hydrogen storage materials. Among all transition metals, titanium and its show great catalytic effects on magnesium hydride. In this study, first time, TiO2 nanosheets with exposed {001} facets were synthesized doped into MgH2. The nanosheet (NS)-doped MgH2 showed superior kinetic performance lowest desorption temperature. onset temperature + 5 wt% NS release was 180.5 °C corresponding...
CoS2 and FeS2 nanoparticles with mesoporous structures embedded in carbon polyhedrons are prepared by reasonable design of materials (CoS2-FeS2-NC), which used as a modified cathode material. This composite material can limit the shuttling polysulfides catalyze adsorb polysulfides. Further, electrochemical properties Li–S batteries enhanced. using S/CoS2-FeS2-NC electrodes have best cycle rate performance. The cathode's initial discharge capacity at 0.2C is 938.9 mAh g–1, while its...
Asymmetric hot rolling was used to fabricate the high-strength Mg-9Gd-4Y–1Zn-0.8Mn (wt.%) alloys, which is strengthened by lamellar long-period stacking ordered (LPSO) phases inside grains and block-shaped LPSO surrounding grain boundaries. The reduction in total thickness shows a significant impact on microstructure, texture, mechanical properties of alloy sheets. By keeping velocity ratio between top lower rollers at 1.3, shear strain introduced all across sheet thickness. as-rolled sample...
A mixed-dimensional photodetector was constructed to convert the harmful surface states of low-dimensional materials into their constructive interface states.
Ultrahigh-strength Mg-9.2Gd-4.4Y-1.0Zn-0.8Mn (wt%) alloys were produced through isothermal ageing at 200 °C applied to pre-ageing-extruded bars. The remarkable thermal stability exhibited by the β and LPSO phases ensures that recrystallization state of α-Mg grains morphology distribution secondary in peak-aged resemble those observed as-extruded micron scale. microstructure is characterized bimodal with a pronounced fibrous texture, major strengthening consisting prismatic β' basal γ'...
A yellow-orange nitrogen-doped zinc oxide (ZnO:N) film was deposited on a quartz glass substrate at 510K by reactive radio-frequency magnetron sputtering of ZnO target with gas nitrogen. The lattice constants the as-grown ZnO:N are much larger than those undoped ZnO, and decrease increasing annealing temperature due to escape nitrogen from tensile stress, accompanied color change pale yellow. occupies two chemical environments in based x-ray photoelectron spectroscopy measurement. One is NO...
A wurtzite N-doped MgZnO film with 20at.% Mg (MgZnO:N) was grown by plasma-assisted molecular beam epitaxy on c-plane sapphire using radical NO as oxygen source and nitrogen dopant. The as-grown MgZnO:N behaves n-type conduction at room temperature, but transforms into p-type after annealed for 1h 600°C in an O2 flow. has a hole concentration of 6.1×1017cm−3 mobility 6.42cm2∕Vs. X-ray photoelectron spectroscopy measurement indicates that substitution N O site is forms atom (N)O molecule...
Telluriums (Te) with various nanostructures, including particles, wires, and sheets, are controllably synthesized by adjusting the content of polyvinylpyrrolidone (PVP) in a facile solvothermal reaction. Te nanostructures all have complete grain sizes excellent crystallinity mesopore structures. Further, formation mechanisms proposed to be that primary nuclei released from reduction TeO32− using N2H4·H2O, then grow into depending on different PVP. These exhibit photocatalytic activities for...
The shuttling effect of polysulfide and its sluggish reaction kinetics are the primary issues with lithium–sulfur (Li–S) batteries. In this work, an improved coimpregnation technique was used to add cobalt atoms nitrogen-doped carbon nanotubes (Co-NCNTs) compound them onto mesoporous silicon (SiO2). Co-NCNTs/SiO2 composites were then as modification materials for Li–S battery separators, which capable physical chemical adsorption lithium (LiPSs). Between silica LiPSs, there is well in...
