Comprehensive knowledge over the shape of nanomaterials is a critical factor in designing devices with desired functions. Due to this reason, systematic efforts have been made synthesize materials diverse nanoscale regime. Anisotropic are class which their properties direction-dependent and more than one structural parameter needed describe them. Their unique fine-tuned physical chemical make them ideal candidates for devising new applications. In addition, assembly ordered one-dimensional...
We describe a simple and efficient methodology for the aqueous synthesis of stable, uniform, size tunable Au@Ag core-shell nanoparticles (NPs) that are stabilized by citrate ions. The synthetic route is based on stepwise Ag reduction preformed Au NPs. final NPs therefore their optical properties can be modulated at least from 30 to 110 nm either tuning shell thickness or changing core. resemble those pure similar sizes, which was confirmed means Mie extinction calculations. additionally...
Ni and NiSn supported on zirconia (ZrO2) indium (In)-incorporated (InZrO2) catalysts were prepared by a wet chemical reduction route tested for hydrogenation of CO2 to methanol in fixed-bed isothermal flow reactor at 250 °C. The mono-metallic (5%Ni/ZrO2) showed very high selectivity methane (99%) during hydrogenation. Introduction Sn this material with the following formulation 5Ni5Sn/ZrO2 (5% Ni-5% Sn/ZrO2) rate formation be 0.0417 μmol/(gcat·s) 54% selectivity. Furthermore, combination...
Here, we report a nonprecious mesoporous adsorbent obtained from the carbonization of bagasse. The material shows an impressive pH-dependent property for cationic, anionic, and commercially used dyes along with organic contaminant (4-nitrophenol) in water. specific surface area ∼462 m2 g–1 porous layered structure as confirmed by gas adsorption microscopic techniques, respectively. Further, pH triggered methylene blue (MB, cationic dye), Congo red (CR, anionic commercial hair dye were...
Abstract Surface‐enhanced enhanced Raman spectroscopy (SERS) has emerged as a powerful analytical technique for ultrasensitive and label‐free detection of chemical species, with numerous applications in various fields. Recently, 2D MXenes, have evoked substantial intrigue promising substrates SERS. Hence, comprehensive understanding the developments effect mechanisms involved SERS is highly crucial. The review reflects advances, working principle, dual mechanisms, including SERS's...
The discharge of CO 2 into the atmosphere has become a crucial issue for mankind and great threat to environment due escalating consequences global warming.
This work demonstrates the development of mesoporous trimetallic oxide scaffolds (TOSs) as heterogeneous catalysts for solvent-free transformation CO2 into various value-added products. The TOS catalyst was prepared using a solution-combustion protocol time- and energy-saving method cobalt, magnesium, cerium metal nitrate salts precursors ethylene glycol fuel system compared with their monometallic counterparts. Characterization suggested strong metal–metal metal–oxygen interactions in...
Flexible and in-plane micro-supercapacitor with high volumetric capacitance based on ultrathin Co(OH) 2 nanosheets.
We report the shape transformation of gold nanorods to spherical nanoparticles, assisted by cupric ions. The reaction proceeds through a series structures and could be arrested at any stage produce particles desired shape. In presence larger concentration cetyltrimethylammonium bromide (CTAB), selective etching tips occurs greater extent. subsequent is driven surface reconstruction generate more stable surfaces. As stability various surfaces depends on protecting agent used, reactivity...
We have developed a room-temperature solution-phase route for the preparation of one-dimensional silver telluride nanowires (Ag2Te NWs). The Ag2Te NWs 600 nm length and 20 diameter were synthesized by reaction tellurium (Te NWs) with nitrate (AgNO3) in water. propose that Te act as template reducing agent simultaneously, enabling formation polycrystalline NWs. Various microscopic spectroscopic tools, such HRTEM, SEM, EDAX, XRD, DSC, XPS, Raman, used characterization phase transition...
