WebThe catalysts are prepared via the incipient wetness method over activated carbon, derived from palm kernel shells. The surface morphology and particle size distribution are examined via field emission scanning electron microscopy, while crystallite size is determined using the wide-angle X-ray scattering and small-angle X-ray scattering methods. WebApr 11, 2024 · All catalysts in these three sets were prepared by incipient wetness impregnation. The palladium precursor was 10 wt % palladium(II) nitrate solution in 10 wt % nitric acid loaded on the catalyst support (multiple aliquots to ensure uniformity, followed by drying in the air after each impregnation) and then calcined in air at 350 °C for 6 h.

WebApr 11, 2024 · The Pd/ZMO-30 catalyst is synthesized using the incipient wetness impregnation method. After impregnation, the sample is dried overnight at 80 °C and further calcined in a muffle furnace at a rate of 1 °C min -1 , heated to 350 °C, and calcined for 2 h to obtain the Pd/ZMO-30 catalyst. WebIn detail, ceria was introduced into carbon support by incipient wetness impregnation, and subsequently, Pd was impregnated by the deposition–precipitation method followed by conventional chemical reduction using NaBH 4. The addition of ceria clearly enhanced the catalytic activity of Pd/C. Such a controlled preparation method enabled us to ...
