A New Type of Strong Metal-Support Interaction Caused by Antimony Species

Metal–support interactions for heterogeneous catalysis: mechanisms, characterization techniques and applications

“…No signicant divergence was observed in the powder X-ray diffraction (XRD) pattern, but signicantly at 2q ∼19°, as shown in Fig. 13d and h, the peak Al 2 O 3 -T was observed on the sample, which can be attributed to the (111) surface, but not on Al 2 O 3 -P. Therefore, an excellent performance, higher selectivity, good activity, and stability we observed for the catalyst containing Al 2 O 3 (110).…”

“…Benhmid et al prepared numerous Pd-Sb catalysts loaded on various metal oxides by the impregnation method. 110 The results showed the nearly complete inhibition of the adsorption catalyst submitted to high temperature reduction (HTR), the inhibition is overcome by the reduction in the oxidization of the Pd/MeO x catalyst followed by metal element at 453 K (LTR), and is attributed to the impact of SMSIs of the Schottky species of alternative reducible supports such as titanium dioxide, ZrO 2 , CeO 2 and Nb 2 O 5 . Lin et al synthesized Ru/ CeO 2 catalysts via impregnation and drying strategies.…”

“…As an example, Qiu et al prepared ordered Co NP arrays on silicon and titania single crystals employing a polymer reverse particle encapsulation method. 155 Compared with Co NPs on SiO x Si, the stronger MSIs between Co NPs on TiO 2 (110) resulted in the retention of larger interparticle distances, and the important amendment in morphology nally resulted in the omelet-like form of Co NPs. For higher performance, there is space for additional optimization/tuning of the Co NPs/TiO 2 interface, especially the application of heat, and therefore the properties of the reactive gas atmosphere, presumably together with the target initial particle size.…”
