The present invention is an air cleaner that uses molecular sieves, such as zeolite or other microporous / nanoporous crystalline materials with pore sizes ranging from 4 Å to 20 Å, as a filter to remove contaminant gas. The contaminants are adsorbed into the porous material along with ions clusters, or any other oxidant generated by a generating device within the system. The contaminant gas is then catalytically decomposed in the confined space of the pore. In one embodiment, transition metal is incorporated into the porous material, and a heater is installed to substitute or accompany the oxidant-generating device. When the heater is turned on, the contaminant is decomposed within the pores of the materials with the transition metals acting as catalysts. Ultimately, the non-harmful byproducts are the small sized water molecutes and carbon dioxide molecules. Growth of bacteria is also suppressed under a clean and dry condition.

The invention belongs to the technical field of membranes, and particularly relates to an imidazole-type hybrid anion exchange membrane and a preparation method thereof. The main body of the imidazole-type hybrid anion exchange membrane has a crosslinked structure and is dispersed with silicon spheres therein; and an ion exchange group is an imidazole-type positively-charged group. By the preparation method, a polymer can be loaded with a cationic functional group and the silicon oxide spheres can be loaded onto a hybrid membrane effectively, and the hybrid anion exchange membrane with good conductive performance and stable chemical properties can be obtained; polymer brominated polyphenyl ether is prefunctionalized by using vinyl imidazole to form relatively large ion clusters beneficial to conduction, and imidazole-type cations have relatively good chemical stability in an alkaline environment; double bonds of the vinyl imidazole can react under the catalytic action of ultraviolet light to form the crosslinked structure, thus benefiting the size stability and the chemical stability of the imidazole-type hybrid anion exchange membrane; and the used modified silicon spheres can be uniformly dispersed into the hybrid membrane, with good compatibility, thus benefiting the chemical stability of the hybrid membrane.

The invention discloses a metal organic framework fertilizer and a preparation method thereof. The novel fertilizer is prepared from a nutrient molecule and an outer framework thereof. The metal organic framework fertilizer is characterized in that the outer framework is prepared from an inorganic metal ion cluster and an organic joint under a hydrothermal condition through coordination. The metalorganic framework material is divided into a metal organic framework material containing zinc and a metal organic framework material not containing zinc. Hydrothermal synthesis conditions for the novel metal organic framework material fertilizer are as follows: the reaction temperature is 100 DEG C, reaction time is 24 hours, the heat-up rate of a reaction kettle is 2 DEG C / min, and rotation speed of a stirrer is 120 revolutions per minute. The novel fertilizer is prepared from the following nutrients: a compound I prepared from 4-5% of N and 16-20% of P, and a compound II prepared from 5-7%of N, 15-18% of P and 2-3% of Zn. According to a soil cultivation test, the novel metal organic framework material fertilizer has good nutrient controlled-release effect, and increases utilization rate of nutrients.
