Mechanochemical Synthesis of Defective Molybdenum Trioxide, Titanium Dioxide, and Zinc Oxide at Room Temperature

“…Defect engineering in metal oxide semiconductors has been demonstrated as an effective route to tune their performances, because the defect structures of metal oxide semiconductors strongly affect their fundamental chemical and physical properties as well as practical applications. − For instance, molybdenum trioxide (MoO 3 ), a stable n-type metal oxide semiconductor with a bandgap of 3.2 eV, can show metallic behavior when the detects such as hydrogen doping are introduced because of the increase of free carrier concentration. − As a result, the defective MoO 3 exhibits localized surface plasmon resonance (LSPR) which are widely investigated in noble metal nanomaterials. , Additionally, the introduction of vacancy-oxygen defects into TiO 2 is able to enhance its visible light absorption as well as photocatalytic activity . To date, several approaches have been developed to prepare defective MoO 3 , TiO 2 , and ZnO.…”

A Sensitive and Selective Method for Visual Chronometric Detection of Copper(II) Ions Using Clock Reaction

“…Although the plasmonic nanoparticle-based assays are able to improve the sensitivity, the nanoparticle probes are easily affected by environmental conditions such as salts, temperature, and thiol-containing substances. [18][19][20][21][22][23][24][25][26] Moreover, the plasmonic nanoparticle is metastable, which gradually aggregates with time. These drawbacks seriously influence their analytical performance in terms of accuracy, reproducibility, and practicality.…”

Supersonic gas flow for preparation of ultrafine silicon powders and mechanochemical synthesis

“…The supersonic gas mill, also called the jet mill, can be used for grinding materials, in which solid particles break up upon a collision based on the jet of compressed air or inert gas [26,27]. It has been used across a number of industries, including food and pharmaceutical manufacturing [28][29][30][31]. The distinct advantage of the supersonic gas mill product is to avoid the contamination.…”

“…It is very suitable for continuous and scalable mechanochemical synthesis because the solid particles impact the physical target at a high speed, which is able to effectively convert mechanical energy to trigger a chemical reaction. In addition, the reaction products are easily separated from the gas stream by cyclonic separation in time [29][30][31][32]. However, the use of the supersonic gas mill for conducting solvent-free mechanochemical synthesis has not been explored to date.…”
