In this paper, we prepared a series of Ce1-xTixO2 (x = 0-0.20) nanorods by hydrothermal method, which were used to construct the PdCu/Ce1-xTixO2 catalysts. The Ce1-xTixO2 and PdCu/Ce1-xTixO2 samples were characterized by transmission electron microscope (TEM), XPS, N2 adsorption-desorption, X-ray diffraction (XRD), inductively coupled plasma optical emission spectrometer (ICP-OES), etc. Catalytic activity, stability, and repeatability of the catalysts for methanol oxidation were investigated. The results show that doping a proper amount of titanium could strengthen the interaction between Ce1-xTixO2 support and PdCu nanoalloy, thus increasing the oxygen vacancy concentration and promoting Pd species with a higher oxidation state. These modified properties are beneficial for the deep oxidation of methanol. The light-off temperature (T50) and full-conversion temperature (T90) of methanol over the PdCu/CeO2 catalyst are 108 °C and 159°C, resp. The greatest activity improvement is found for PdCu/Ce0.9Ti0.1O2, which shows the lowest T50 of 88°C and T90 of 138°C. Furthermore, neither PdCu/CeO2 nor the modified PdCu/CeO2 catalyst produces byproducts and exhibit excellent stability and repeatability throughout the whole test period. This study provides a reference for in-depth understanding and designing of efficient and stable CeO2-based oxidation catalysts. This study involved multiple reactions and reactants, such as Sodium tetrachloropalladate(II) (cas: 13820-53-6Computed Properties of Cl4Na2Pd).
Sodium tetrachloropalladate(II) (cas: 13820-53-6) belongs to organic chlorides. Organochlorines are organic compounds having multiple chlorine atoms. They were the first synthetic pesticides that were used in agriculture. They are resistant to most microbial and chemical degradations. Alkyl chlorides are versatile building blocks in organic chemistry. While alkyl bromides and iodides are more reactive, alkyl chlorides tend to be less expensive and more readily available.Computed Properties of Cl4Na2Pd
