Pt-based high-entropy-alloy nanoparticles (HEA-NPs) have excellent physical and chemical properties due to the diversity of composition, complexity surface structure, high mixing entropy, nanoscale, they are used in a wide range catalytic applications such as ammoxidation, electrolysis water produce hydrogen, CO2/CO reduction, ethanol/methanol oxidation reaction. However, offering facile, low-cost, large-scale method for preparing HEA-NPs still faces great challenges. In this study, we...
Nanoscale tungsten (W) powder is used in some special materials. In this study, a hollow superstructure W consisting of nanoparticles was synthesized by spray drying combined with two-step calcination from commercial (NH4)6W7O24·6H2O. The high-pressure gas (HPG) the significant factor process, which affect BET surface area and average particles size spray-dried powders. detailed influences calcined steps temperature microstructure final were investigated. distribution as-synthesized...
A facile, adjustable, and expandable synthetic technique to make three-dimensional (3D)-nanoframework nanomaterials with super-large surface areas is of great significance in the field electrocatalysts. In this study, spray-drying combined thermal decomposition reduction employed synthesize single-metal Pt, Pt-based multimetallic, high-entropy alloy (HEA) 3D-nanoframeworks under mild conditions (at 300 °C a H2 atmosphere). It found that as-synthesized Pt 3D-nanoframework shows 94.9 m2/g...
We demonstrate that the work function of a metal gate can be varied by inserting very thin layer ("metal A") between thick B") and dielectric. The flat band voltage (VFB) MOS (metal-oxide-semiconductor) capacitor structure controlled within range bounded A B individually, as demonstrated with various stacked bi-metal layers. For continuous layers, we speculate tunability may due to drastic change electron density in direct contact bulk metal. This results larger junction depth than expected...
The Eu–TiO 2 /PVDF membrane can adsorb the organic dye methyl orange (MO), degrade antibiotic ciprofloxacin (CIP) under visible-light irradiation, and simultaneously a mixture of MO CIP.
Exploiting efficient and inexpensive electrocatalysts for the oxygen reduction reaction (ORR) evolution (OER) is of great significance rapid development renewable energy technologies. The embedding single-atom metals into two-dimensional (2D) carbon-based materials as fuel cells metal-air batteries have become a major research focus. Herein, catalytic properties ORR OER partial metal atoms embedded in h-BCN monolayer were systematically investigated on thermodynamic kinetic scales using...
Design and fabrication of a non-Pt hydrogen evolution catalyst for acidic alkaline solutions are paramount significance water splitting. Herein, we proposed method through spray-drying coupling high-temperature reduction, which had simple, efficient, wide-scale applications compared with the traditional synthetic process, RuCo NPs/CNTs was fabricated successfully. Zero-dimensional (0D) nanoparticles (<10 nm) embedded on one-dimensional (1D) CNTs uniformly involving each other could offer...
The search for suitable synthesis methods and parameters capable of controlling the length, diameter, yield silver nanowires (AgNWs) is still an emerging strategy today. Therefore, a method high-yield long AgNWs via chromic chloride stable reaction environment was proposed. results show that Cr 3+ could restore adsorbed atomic oxygen quickly provide high efficiency in prevention oxidative etching, ion 2+ oxidized to has lower standard electrode potential, more provided by coupling avoid...

Abstract (NH 4 ) 2 RuCl 6 is an important precursor in the synthesis of Ru powder with high-purity requirement. In this study, (>99.999 wt%) micro-sized pieces were synthesized by distillation and precipitation from crude powder. Then, thermal decomposition behavior was investigated. The process included two stages. First, decomposed 255.0°C to 314.0°C, endothermic peak located at 309.4°C. At stage, HCl NH 3 released, while dense micro-pieces transformed loosened due decomposition. solid...
