摘要
The effect of potassium on the Pt supported hydrotalcite catalyst (Pt-KHT) was investigated in the aqueous phase reforming (APR) of glycerol for the efficient production of H-2. Pt-KHT was prepared by the sequential incipient wetness impregnation method where impregnation of K was carried out first followed by incorporation of Pt. The catalyst, was characterized by XRD, SEM, HRTEM, XPS, FTIR, TPR, and TPD. The TEM images of the catalyst showed highly dispersed Pt-species supported on hydrotalcite with needle-like structure. The addition of potassium (K+) increases the basicity of the Pt-KHT catalyst and enhances the production of hydrogen through APR of glycerol. The gaseous product formed over Pt-KHT at 250 degrees C was 99.4% which is higher than that obtained of Pt-HT catalyst, and an H-2 selectivity of 67.4% was achieved over Pt-KHT after 3 h of reaction.
