Abstract: Disclosed are a retractable camera module and an electronic device, wherein a lens of the retractable camera module is retractable relative to a photosensitive chip thereof, so as to be switched between a working state and a non-working state, wherein in the working state, the lens of the retractable camera module is stretched out for imaging, in the non-working state, the lens of the retractable camera module is retracted back to reduce the overall height of the retractable camera module, in this way, the technical contradiction between the overall height dimension and a large effective focal length of the traditional upright camera module is solved.

Abstract: Disclosed is a camera module, which uses a new piezoelectric actuator as a driving element to meet the driving requirement of the camera module. Specifically, the camera module uses the new piezoelectric actuator as the driving element to move an optical camera lens for optical image stabilization. Moreover, the piezoelectric actuator is arranged in the camera module in a rational arrangement scheme, so as to meet both the structural design requirement and the dimensional design requirement of the camera module.

Abstract: The technical field of catalysts, in particular to a combined catalyst and a preparation method thereof, and a method for preparing xylene by coupling carbon dioxide hydrogenation with toluene alkylation. The combined catalyst of the present disclosure having a metal oxide and a zeolite. In the present disclosure, the metal oxide is mainly used to reduce carbon dioxide to methanol, and the zeolite is mainly used to react toluene with methanol to produce xylene. When the catalyst of the present disclosure is used to prepare xylene, carbon dioxide and hydrogen can be used as raw materials instead of methanol. Compared with the traditional alkylation of toluene with methanol, this method can avoid the side reaction of methanol to olefins caused by the improper methanol/toluene feeding ratio, and improve the production efficiency of xylene; meanwhile, it can inhibit xylene isomerization and increase p-xylene selectivity in the products.
