摘要： An aluminosilicate molecular sieve catalyst, its preparation and application thereof are provided. The catalyst shows a desorption curve having three peaks P1, P2 and P3 in its NH3-TPD pattern. The desorption temperatures corresponding to the summits of the three peaks P1, P2 and P3 are respectively in a range of 180-220° C., 250-290° C. and 370-410° C. The catalyst shows a higher activity, selectivity and stability when used for producing alkylaromatic hydrocarbons by gas-phase alkylation of aromatics with olefins.

摘要： A conductive composite material of graphene contains graphene nano-sheets and conjugated copolymers. The conjugated copolymers has alkynyl groups and are in a linear structure and grafted to the graphene nano-sheets. The preparation of conductive composite material includes the steps of: pretreating the graphene nano-sheets with 4-bromobenzenediazonium tetrafluoroborate, and forming the conjugated copolymers in the presence of the pretreated graphene nano-sheets. The conductive composite material of graphene can be uniformly dispersed in an electrode slurry, reduce the internal resistance of an electrode, and improve the electrical conductivity of an electrode. At the same time, the flexible structure associated with the graphene nano-sheets can buffer the volume expansion of the silicon-containing negative materials during charge-discharge cycling. Such a composite material can be in a lithium-ion battery.
