2017年9月14日 · The crystal structure of the synthesized Pt/PtO 2 was characterized by X-ray diffraction (XRD). Fig. 3 a shows: (i) the XRD pattern of fcc structured Pt (JCPDS Card No. 01-1194) (the strong (200) peak in the diffraction pattern indicates that the Pt nanoparticles align flat on the substrate [21] , [22] ); and (ii) together with characteristic ...

2020年8月5日 · The thermal stability of PtO 2 and dislocation density within Pt wire were investigated using differential scanning calorimetry (DSC), Thermogravimetry (TG), X-ray photoelectron spectroscopy (XPS) and X-ray diffraction (XRD) to understand and evaluate the stability of standard platinum resistance thermometer (SPRT), which is the interpolation ...

2001年12月3日 · In the present study, Pt-PtO x thin films were sputter deposited at various substrate temperatures up to 700°C with varying O 2 /Ar ratio. And the films were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and d.c. four probe resistivity measurement.

Indexing XRD patterns correspond to the face-centered-cubic (FCC) lattice of Pt (JCPDF 04-0802), Pd (JCPDF 46-1043) and PdPt alloy (JCPDF 65-6418) structures. ... ... analysis of the position of...

Pt oxide thin films are prepared by sputtering Pt target in an atmosphere containing Ar and O2 gases. Polycrystalline PtO and ®-PtO2 films are obtained in O2 flow ratio regions of 30–50% and 80–100%, respectively, at a substrate temperature of 300±C.

2023年1月9日 · The X-ray diffraction (XRD) pattern of a thin film prepared by casting the PtO x NS colloid onto a glass plate exhibited a series of diffraction peaks with d = 1.67, 0.83, 0.55, and 0.42 nm,...

In this report, chitin and chitosan nanocrystals were used as biomass-based supports for Pd nanoparticles (NPs) used as a heterogeneous catalyst for the Heck coupling reaction. By using a one-pot...

2012年2月1日 · The result shows that PtO is a promising candidate for use as a catalyst, in sensors, as a photo-cathode in water electrolysis, for thermal decomposition of inorganic salt and fuel cells.
