Obtaining tungsten carbides from tungsten bipyridine complexes via low temperature thermal treatment

Tungsten Carbide Microspheres as a Noble‐Metal‐Economic Electrocatalyst for Methanol Oxidation

“…XPS of the W 4f doublet (4f 5/2 and 4f 7/2 ) showed peaks at 31.6 eV and 32.5 eV, arising from the presence of tungsten carbide (see Supporting Information) 14. Peaks observed at higher binding energies indicate that a part of the tungsten is present as an oxide, which probably arises from surface oxidation of W 2 C in air after preparation 15…”

Preparation and performance of nanosized tungsten carbides for electrocatalysis

“…The commercial WC is very low in surface area (about 2 m 2 g −1 ) with the particles in micrometer size. The surface areas of the WC particles synthesized by reported methods were mostly less than 10 m 2 g −1 [18][19][20][21][22][23][24][25][26][27][28]. Therefore, it is necessary to develop novel methods to prepare high surface area WC by reducing the particle size used as catalyst supports since the particle size and the dispersion of the support are crucial for the catalytic reactions.…”

Tungsten Carbide Microspheres as a Noble‐Metal‐Economic Electrocatalyst for Methanol Oxidation

“…[14] Peaks observed at higher binding energies indicate that a part of the tungsten is present as an oxide, which probably arises from surface oxidation of W 2 C in air after preparation. [15] The microscopic images of carbon and W 2 C microspheres are shown in Figure 2. Both microspheres showed uniform morphology with diameters of 2-4 mm.…”
