Optimization of electrochemical parameters for the fabrication Zn(1,3-bdc)<sub>0.5</sub>bzim nano-MOF as a drug adsorption platform.
Well-dispersed Au and Ag nanoparticles (NPs) have been immobilized on a zinc imidazolate metal-organic framework, Zn(mim), using the "one-pot" method tested as catalysts in ammonia borane hydrolysis. The AuNPs@Zn(mim) AgNPs@Zn(mim) materials were characterized by FTIR, XRD, ICP-OES, TGA, BET, SEM, TEM. catalyst showed high yield (98.5%) hydrogen generation rate (3352.71 mL min
Abstract Ammonium is a pollutant commonly detected in various water sources and, high concentrations, poses significant risks to environmental quality and public health. Numerous techniques have been developed are currently employed eliminate pollutants, including ammonium ions, from water. Among these methods, adsorption has proven be the most cost-effective eco-friendly, particularly when utilizing an inexpensive effective adsorbent. This study aims determine optimal method for producing...
Abstract Metal‐organic frameworks (MOFs) comprise a broad class of crystalline materials defined as porous networks consisting metal ions or clusters interconnected through polytopic organic linkers. Due to their intriguing structural and topological characteristics which usually offer high surface areas tunable pore size, MOFs are excellent candidates for great variety applications, such gas adsorption separation, catalysis, magnetism, photoluminescence many others. Although attractive,...
Tunable photoluminescence was observed as a function of the excitation wavelength.
Thin ceramic powders of zinc aluminate ZnAl2O4 co-doped with Er3+ and Yb3+ were prepared by a combustion reaction characterized from the spectroscopic point view, aim investigating effect mechanisms upconversion emissions. The characteristic cubic spinel structure was predominantly formed for all doped samples, intense emission observed in green red spectral regions, under 980 nm diode laser excitation. mechanism both emissions confirmed to involve two photon absorptions it found that...
Nickel-based catalyst precursor for dry reforming of methane was successfully prepared by a self-combustion method. Three different amino acids: urea, glycine and citric acid were tested as fuels in the redox reaction with metal nitrates. For each fuel, thermodynamic modeling combustion performed. The samples characterized X-ray diffraction (XRD), Thermogravimetric analysis (TG), Scanning electron microscopy (SEM), Attenuated total reflectance – Fourier transform infrared (ATR-FTIR)...
Abstract The development of novel and high‐performance cathodes is a critical issue to be addressed in order reduce Solid Oxide Fuel Cells (SOFCs) operation temperature the 600‐800 °C range or less. performance CeO 2 ‐based composite very attractive such operational temperatures. In this work, La 0.6 Sr 0.4 Co 0.2 Fe 0.8 O 3 (LSCF) Ce Sm 1.9 (SDC) powders were synthesized by different synthesis methods mechanically mixed prepare LSCF‐SDC cathodes.
