Quasi-spherical undoped ZnO and Al-doped nanoparticles with different aluminum content, ranging from 0.5 to 5 at% of Al respect Zn, were synthesized. These evaluated as photocatalysts in the photodegradation Rhodamine B (RhB) dye aqueous solution under UV-visible light irradiation. The nanopowder annealed at 400 °C resulted highest degradation efficiency ca. 81% after 4 h green irradiation (525 nm), presence mg catalyst. samples characterized using ICP-OES, PXRD, TEM, FT-IR, 27Al-MAS NMR,...
This work explores the synthesis and characterization of undoped ZnO, Ga-doped ZnO (Ga:ZnO), γ-Ga2O3 quasi-spherical nanoparticles their catalytic activity in Rhodamine B photodegradation under UV–visible light exposure. Gallium dopant incorporation into Ga:ZnO was confirmed by inductively coupled plasma optical emission spectroscopy (ICP-OES), Fourier transform infrared (FT-IR), powder X-ray diffraction (XRD), maintaining hexagonal wurtzite structure with an additional zinc gallium...
This study reports the low temperature and pressure conversion (up to 160 °C, p = 3.5 bar) of CO2 H2 CO using plasmonic Au/TiO2 nanocatalysts mildly concentrated artificial sunlight as sole energy source 13.9 kW·m−2 suns). To distinguish between photothermal non-thermal contributors, we investigated impact Au nanoparticle size light intensity on activity selectivity catalyst. A comparative P25 TiO2-supported a 6 nm 16 displayed 15 times higher for smaller particles, which can only partially...
This work introduces a polymeric backbone eutectogel (P-ETG) hybrid solid-state electrolyte with an N-isopropylacrylamide (NIPAM) for high-energy lithium-ion batteries (LIBs). The NIPAM-based P-ETG is (electro)chemically compatible commercially relevant positive electrode materials such as the nickel-rich layered oxide LiNi0.6Mn0.2Co0.2O2 (NMC622). chemical compatibility was demonstrated through (physico)chemical characterization methods. nonexistence (within detection limits) of interfacial...
The preparation of Ru nanoparticles supported on γ-Al2O3 followed by chemical reduction using RuCl3 as a precursor is demonstrated, and their properties are compared to prepared impregnation with Ru3(CO)12 subsequent thermal decomposition. resulting from slightly larger (1.2 vs. 0.8 nm). In addition, were deposited Stöber SiO2 both deposition techniques. These particles than the ones (2.5 3.4 nm for decomposition, respectively). Taking into account size differences between nanoparticles, all...
Sodium-ion batteries (SIBs) are a more sustainable alternative to lithium-ion (LIBs) considering the abundance, global distribution, and low cost of sodium. However, their economic impact remains small compared LIBs, owing in part lag materials development where significant improvements energy density safety remain be realized. Deep eutectic solvents (DESs) show promise as alternatives conventional electrolytes SIBs because nonflammable nature. practical application has thus far been...
Solid electrolytes are regarded as good alternatives for liquid carbonate-based electrolytes, they show much better safety. In polymeric eutectogel (P-ETG) hybrid solid-state a deep eutectic solvent (DES) is enclosed within polymer host. They promising application in high-energy-density lithium-ion batteries (LIBs) due to their relatively high ionic conductivity at room temperature, compatibility with high-potential positive electrode materials, and improved safety compared conventional...
