改性秸秆灰负载Pt催化甘油氧化性能研究Glycerol oxidation catalyzed by modified straw ash supported Pt
Published 2025-08-01“…In order to achieve high value utilization of biomass, Pt-based catalysts of Pt/ash-b, Pt/ash-a, Pt/ash-ba and Pt/ash-CeO2 were prepared by pre-treating straw ash using alkali modification, acid modification, combined acid and alkali modification, and introduction of CeO2, respectively. The composition, structure, loading amount of Pt, size of Pt particle, surface acidity and alkalinity, and Pt reduction activity of the catalysts were determined by X-ray fluorescence spectroscopy (XRF), X-ray diffraction (XRD), inductively coupled plasma-atomic emission spectroscopy (ICP-OES), transmission electron microscopy (TEM), CO2 programmed temperature-raising desorption (CO2-TPD) and NH3 programmed temperature-raising desorption (NH3-TPD), and hydrogen-programmed temperature-raising reduction (H2-TPR), respectively. …”
