일반 설명
Ammonium metatungstate is a Keggin-type heteropoly compound. It can be prepared by polycondensation of ammonium tungstate solutions. It is widely used as a precursor for preparing tungsten catalysts for hydrocracking and as a fuel cell catalyst.
애플리케이션
Ammonium metatungstate can be used as a precursor to synthesize:
- Carbon-supported tungsten catalyst for hydrogenolysis of cellulose.
- Reduced tungsten and mixed tungsten oxide catalysts for bifunctional hydroisomerization of n-alkanes.
- Hybrid 2D/3D tungsten diselenide transistors via chemical vapor deposition method.

WO3-treated fullerene/TiO2 composites (WO3-fullerene/TiO2) were prepared using a sol-gel method. The composite obtained was characterized by BET surface area measurements, X-ray diffraction, scanning electron microscopy, energy dispersive X-ray analysis, transmission electron microscopy, and UV-vis analysis. A methyl orange (MO) solution

By understanding how the environmental composition impacts the optoelectronic properties of transition metal dichalcogenide monolayers, we demonstrate that simple photoluminescence (PL) measurements of tungsten disulfide (WS2) monolayers can differentiate relative humidity environments. In this paper, we examine the PL and

While a hexagonal WS2 monolayer, grown by chemical vapor deposition, exhibits distinctive patterns in photoluminescence mapping, segmented with alternating S-vacancy (SV) and W-vacancy (WV) domains in a single crystal, the formation mechanism for native alternating defect domains remains unresolved to

Glycerol surplus from biodiesel synthesis still represents a major problem in the biofuel production chain. Meanwhile, those in the acrylic acid market are looking for new processes that are able to offer viable alternatives to propylene-based production. Therefore, acrylic acid

Nanophotonic devices manipulating light for high-speed computing are a counterpart of speed-limited electronic circuits. Although plasmonic circuits are a promising platform for subwavelength miniaturization, the logic-operation principle is still limited to mimicking those of photonic waveguides using phase shifts, polarization
