ZnO/vermiculite as the novel photocatalysts were prepared by two approachs: one is mixtures of ZnO and different acid treated vermiculite, and another is sol-gel method. The acid activated vermiculite as a new promising catalyst support and adsorbent has a large capacity of absorption, high surface area and thermal stability. The activity of catalyst has been interrelated to support and ZnO. Based on the important effect of support on ZnO/vermiculite photocatalysts, treatment of vermiculite by nitric acid of different concentration was studied by evaluated in the photocatalytic decomposition of MB with resulting photocatalysts. BET surface area measurement and X-ray diffraction (XRD) analysis were used to characteristic of ZnO particle in acid treated vermiculite structure and the phase structure and crystallization index of ZnO in the modified vermiculite mineral. Results showed the ZnO-vermiculite combination possessing higher photocatalytic activity due to the synergistic effect when compared to the commercial ZnO.

AbstractResearchers normally consider MgO as a promising high-surface-area heterogeneous catalyst support, additive, and promoter for many kinds of chemical reactions due to its certain properties, including stoichiometry and composition, cation valence, redox properties, acid-base character, and crystal and electronic structure. The presence of MgO as a support catalyst also modifies the electronic state of the overall catalytic performance by electron transfer between the native catalyst and MgO as support. The influence is clarified by alteration of acid-base properties of the catalyst-supported MgO. Meanwhile, the method, chemical composition, and condition in the preparation of MgO are the important factors affecting its surface and catalytic properties. Therefore, MgO with a high surface area and nanocrystalline structure has encouraging applications for some reactions, including as dry reforming, dehydrohalogenation, oxidative dehydrogenation of butane, nonoxidative dehydrogenation of ethylbenzene, decomposition of CCl

A series of γ-Al2O3 modified with different content of polyethylene glycol (PEG) was prepared by a reverse precipitation method. The phase transformation, thermal stabilization and the morphology of PEG-modified γ-Al2O3 was studied by XRD, BET and TEM, respectively. The results showed that the γ-Al2O3 with 1mol% PEG-modified has the excellent thermal stabilization after calcined at 1100°C for 3h. With the content of PEG increasing, the surface area of γ-Al2O3 was reduced gradually. Simultaneity, the γ-Al2O3 phase was transferred to θ-Al2O3 with the surface area 92 m2g-1 and a pore volume of 0.77 cm3g-1. The high surface area maintained at such high treatment temperature shows the 1mol% PEG-modified γ-Al2O3 prepared by reverse precipitation method can be applied in the automotive three-way catalyst support.
