Problems solved by technology

However, the conversion efficiency of biochemical and photochemical methods is low, and thermochemical methods require harsh reaction conditions such as high temperature and high pressure, so large-scale use is not suitable.
In view of my country's vigorous development in the field of new energy, renewable clean energy (wind and solar) power generation is relatively considerable, but clean energy such as wind and solar has strong intermittency, randomness, volatility and anti-peaking. The impact of the power grid is large and it is difficult to merge into the grid, thus causing a lot of waste of these electric energies

Embodiment 1

[0035] The present embodiment is the preparation of bismuth carbonate, and the specific preparation steps are as follows:

[0036] Dissolve 0.272 g of sodium acetate trihydrate in 20 ml of deionized water by sonication, named solution 1, and then add Bi(NO 3 ) 3 .5H 2 O (0.972g) and ethylene glycol (50ml) were mixed for 20min, named as solution 2, the solution 1 and solution 2 were mixed and ultrasonicated for 1 hour, then the solution was transferred to the autoclave and the temperature of the reaction was set to 180 degrees and the reaction time For 12 hours, after the solution is cooled, mix with ethanol and water in a volume ratio of 1:1, then set the rotating speed to 8000 for centrifugal washing 6 times, and finally dry in a 60-degree oven for 12 hours to obtain bismuth carbonate nanomaterials.

[0037] refer to figure 1 , which corresponds to the SEM image of the bismuth carbonate nanosheets composed of uniformly distributed nanoparticles of the present invention. It...

Abstract

The invention relates to the technical field of electrochemistry, in particular to a bismuth carbonate nano material and a preparation method and application thereof. The invention discloses a bismuth carbonate nano-material, which is composed of uniformly distributed bismuth carbonate nano-particles, has a large specific surface area, greatly improves the catalytic reduction ability, and shows high catalytic activity and selectivity at room temperature and under mild conditions in the process of preparing formic acid by electrocatalytic reduction of CO2. In addition, the bismuth carbonate nano material also has relatively high current density (gt; 100 mA cm <-2 >).

Description

technical field [0001] The invention relates to the technical field of electrochemistry, in particular to a bismuth carbonate nanomaterial and a preparation method and application thereof. Background technique [0002] Hydrogen fuel cells have the advantages of high fuel energy conversion rate, low noise and zero emissions, and can be widely used in vehicles such as automobiles, planes, trains, and stationary power stations. Since the application of fuel cells in manned spaceflight, underwater submarines, and distributed power stations, fuel cells have always attracted the attention of governments and enterprises. As the scale of energy technology increases, the entire upstream power structure will become cleaner. [0003] Therefore, how to safely and simply prepare and store hydrogen has become an important direction for the development of fuel cell research. In addition to hydrogen fuel cells, formic acid fuel cells have been widely studied due to their high energy densi...
