Embodiment

[0025] Step 1) Weigh 0.75g of cobalt nitrate hexahydrate, dissolve it in 9 ml of absolute ethanol, then weigh 0.428 g of terephthalic acid and dissolve it in 36 ml of N,N-dimethylformamide, and magnetically stir until a clear solution , mixed in a water bath at 40 °C, and ultrasonically treated for 15 min;

[0026] Step 2) Put the ultrasonic solution in step (1) into a reaction kettle with a Teflon substrate, and place it in a 100°C oven for 24 hours. After the reaction, control the oven to cool down to room temperature at 5°C / min After standing for 2 days, the filtered product was washed three times with N,N-dimethylformamide and absolute ethanol, and dried in an oven at 80 °C for 12 h to obtain cobalt-based MOFs materials.

[0027] In the cobalt-based MOFs material catalytic performance test in the embodiment, the hydrogen desorption performance is calculated by the drainage method. The experimental test results show that the catalytic performance of catalysts with different...

Abstract

The invention discloses a cobalt-based MOFs material. The cobalt-based MOFs material is formed by cobalt-nitrate hexahydrate which is reacted with terephthalic acid through a hydrothermal method, andthen is washed and dried through N, N-dimethyl formamide and an absolute ethyl alcohol solvent. A preparation method comprises the following steps: firstly, adding cobalt-nitrate hexahydrate in absolute ethyl alcohol, and performing magnetic stirring, so as to obtain a clear cobalt nitrate solution, adding terephthalic acid in N, N-dimethyl formamide, and performing magnetic stirring, so as to obtain clear a terephthalic acid solution, and performing mixed ultrasonic treatment on the two solutions; secondly, loading the solution subjected to mixed ultrasonic treatment into a reaction kettle, and arranging the reaction kettle into an oven, ensuring that the solution is reacted under a certain condition, and filtering, washing and drying a reaction product in certain condition after the reaction, so as to obtain the cobalt-based MOFs material. When the material is applied to the catalysis of hydrolysis of sodium borohydride, the hydrolysis speed reaches 1700 to 2400 mL min-1g-1, and thecatalytic performance keeps 47 to 50 percent of the original hydrogen yield after circulation. The material has excellent catalytic performance, and has a wide application prospect in the field of thepreparation of new energy resources.

Description

technical field [0001] The invention relates to the technical field of catalytic chemistry, in particular to a preparation method and application of a cobalt-based MOFs material. Background technique [0002] Environmental pollution and energy shortage are two major problems that need to be solved urgently in today's society. As a new type of energy, hydrogen energy has attracted widespread attention due to its wide range of sources, high combustion calorific value, and environmentally friendly products. Questions about hydrogen mainly focus on the production, storage and transportation of hydrogen, and the production of hydrogen is the first step. At present, the production of hydrogen mainly includes the decomposition of fossil fuels, photocatalytic hydrogen production and aluminum water production, etc.; chemical hydrides and borohydrides as hydrogen production and storage have attracted more and more attention, for example, lithium hydride, Magnesium hydride, sodium bo...
