Embodiment 1

[0032] At 25°C, weigh 0.95g of trimesic acid (H 3 BTC), take a clean beaker, measure 60 mL of anhydrous methanol, then add the weighed drug into it, put it into an ultrasonic machine to ultrasonically disperse the drug in anhydrous methanol, mix and stir until all dissolved, and wait for the solution to dissolve evenly Then, add bismuth nitrate pentahydrate (0.35g), lanthanum nitrate hexahydrate (0.364g), hexadecyltrimethylammonium bromide (0.075g), stir evenly, and after the solution is evenly dissolved, put it into an ultrasonic machine to sonicate 1h, the ultrasonic power is 200W. After the reaction was completed, the product was centrifuged at 10,000 r / min for 5 minutes, and then placed in an oven at 60° C. for 12 hours to obtain MOF (CAU-17-La) material.

[0033] figure 1 The characteristic diffraction peaks of the X-ray powder diffraction pattern of the prepared CAU-17-La material indicate the successful synthesis of MOF.

Abstract

The invention discloses a preparation method for directly synthesizing an MOF material for electrocatalytic reduction of carbon dioxide at room temperature, and belongs to the field of catalysts. According to the method, the surfactant is used for promoting MOF crystallization at the room temperature, the rare earth metal ion salt is used for adjusting the MOF morphology, the MOF material for electrocatalytic reduction of carbon dioxide is synthesized through the combined action of the surfactant and the rare earth metal ion salt, the bismuth-based MOF is directly synthesized at the room temperature to serve as the electrocatalyst, higher catalytic activity is achieved in reduction of CO2, and innovative significance is achieved. The method disclosed by the invention is short in period, high in yield, simple in process operation, stable in product performance, good in catalytic performance and environment-friendly. The method has great research and application potential in the field of electro-catalysis.

Description

technical field [0001] The invention belongs to the field of material preparation and electrocatalysis, in particular to a preparation method for directly synthesizing a MOF material for electrocatalytic carbon dioxide reduction at room temperature. Background technique [0002] Global demand for energy has been rising rapidly over the past few decades due to rapid population and economic growth. The widespread use of fossil fuels has not only led to a rapid depletion of energy sources, but has also led to the release of additional carbon dioxide and other pollutants into our environment, potentially contributing to global warming and the deterioration of the planet. Therefore, the development of efficient and clean energy, CO 2 Fields such as capture and conversion have been increasingly valued by scientists from all over the world. Promoting the closure of the carbon cycle is to reduce CO in the atmosphere. 2 effective means of concentration. At this stage, the developm...
