摘要： The present invention relates to the field of alkylation catalysts, and disclosed are a composite ZSM-5 molecular sieve, a preparation method therefor, a catalyst and an application thereof. A single crystal of the composite ZSM-5 molecular sieve comprises a main crystal and a twin crystal; the main crystal and the twin crystal are both ZSM-5 crystals; a crystal plane [010] of the main crystal is covered by a crystal plane [100] of the twin crystal; and the ratio of the number of sinusoidal pore openings to the number of straight pore openings on the outer surface of the single crystal of the composite ZSM-5 molecular sieve is (0.7-10:1), and the molar ratio Y1 of an Si element to an Al element within 10 nm of the surface is (300-2000):1. The single crystal of the composite ZSM-5 molecular sieve of the present invention has a large ratio of the number of sinusoidal pore openings to the number of straight pore openings, and is aluminum-poor on the surface and aluminum-rich on the inside. When applied to the toluene methanol alkylation reaction to prepare p-xylene, the selectivity of p-xylene may be greatly improved.

摘要： A hydrogen sensitive film, a hydrogen sensor and a preparation thereof. The hydrogen sensitive film has a composite structure of an aerogel and a catalyst. The aerogel can adsorb hydrogen and undergo hydrogenation reaction with hydrogen. The catalyst is a nano-noble metal catalyst for catalyzing the hydrogenation reaction, and is distributed in pores of the aerogel. The hydrogen sensitive film is prepared by mixing a catalyst into an aerogel through physical compounding. The hydrogen sensor includes an insulating substrate layer, the hydrogen sensitive film and an electrode layer.

摘要： Molecular sieves comprising intergrowths of cha and aft having an “sfw-GME tail”, at least one structure directing agent (SDA) within the framework of the molecular sieve, an intergrowth of CHA and GME framework structures, cha cavities, and aft cavities are described. A first SDA comprising either an N,N-dimethyl-3,5-dimethylpiperidinium cation or a N,N-diethyl-2,6-dimethylpiperidinium cation is required. A second SDA, which can further be present, is a CHA or an SFW generating cation. The amount of the second SDA-2 used can change the proportion of the components in the cha-aft-“sfw-GME tail”. Activated molecular sieves formed from SDA containing molecular sieves are also described. Compositions for preparing these molecular sieves are described. Methods of preparing a SDA containing JMZ-11, an activated JMZ-11, and metal containing activated JMZ-11 are described. Methods of using activated JMZ-11 and metal containing activated JMZ-11 in a variety of processes, such as treating exhaust gases and converting methanol to olefins are described.

摘要： A method of making a hydrodesulfurization catalyst having nickel and molybdenum sulfides deposited on a support material containing mesoporous silica that is optionally modified with zirconium. The method of making the hydrodesulfurization catalyst involves a single-step calcination and reduction procedure. The utilization of the hydrodesulfurization catalyst in treating a hydrocarbon feedstock containing sulfur compounds (e.g. dibenzothiophene, 4,6-dimethyldibenzothiophene) to produce a desulfurized hydrocarbon stream is also provided.

摘要： Claimed herein is a method of applying amorphous Co—SiOx to activate PMS and produce SO4.− due to the formation of Co(II)-Ov, pairs via the substitution of Si by Co. The inherent Co significantly change the electronic structure of O and Si atoms in the Co—SiOx via final state effects and increase the conductivity in terms of more effective electron transfers. The claimed method using Co—SiOx functions as a more effective oxidative catalyst for the faster degradation of pollutants. The simplicity of the synthetic procedures indicates that the conductive Co—SiOx could be used for the activation of PMS and other electrochemical applications on a wider scale.

摘要： The present invention relates to the field of catalysts, and provides a porous layered transition metal dichalcogenide (TMD) and a preparation method and use thereof. The preparation method includes the following steps: (1) mixing silica microspheres, a transition metal salt and an elemental chalcogen, and pressing to obtain a tablet, the silica microspheres having a same or different particle diameters; and (2) sintering the tablet under hydrogen, and removing the silica microspheres to obtain the porous layered TMD. The porous layered TMD prepared by the method of the present invention has a high lattice edge exposure, which provides more active sites and higher catalytic activity, so the porous layered TMD can effectively catalyze the oxidation of alcohols to aldehydes or sulfides to sulfoxides under visible light irradiation.
