Název v původním jazyce

Study of synthesis thermal stability and catalytic activity of AgCu nanoparticles

Popis výsledku v původním jazyce

This project is aimed to study thermal and catalytic properties of nanoparticles. The work includes the synthesis of AgCu nanoparticles by the solvothermal hot-injection decomposition method followed by characterization of prepared nanoparticles using the dynamic light scattering, ultraviolet-visible spectroscopy, transmission and scanning electron microscopes with energy X-ray dispersive spectroscopy and powder X-ray diffraction. Catalytic activity of AgCu nanoparticles was characterized by Knudsen effusion mass spectrometry and was compared with activity of the compact AgCu alloy and with the inert SiO2 nanoparticles. It was found out AgCu nanoparticles have significantly higher catalytic activity than bulk material and inert SiO2 nanoparticles. Surface oleylamine was completely decomposed. Acknowledgement: The work has been financially supported by the Czech Science Foundation under the project GA17-15405S and by the Institutional project of Masaryk University MUNI/A/1375/2018. CIISB research infrastructure project LM2015043 funded by MEYS CR is gratefully acknowledged for the financial support of the measurements at the CF Cryo-electron Microscopy and Tomography.
