Problems solved by technology

The water electrolysis process is mainly limited by the oxygen evolution reaction. Ruthenium oxide or iridium oxide are common oxygen evolution electrocatalysts in the industry, but they are expensive.
Ferric oxide is easy to prepare and the price is low, but the performance is poor, the electrochemical active area is small and the conductivity is poor

Embodiment

[0011] Example: Weigh or measure 10 milliliters of octadecenoic acid, 1 gram of sodium hydroxide, and 10 milliliters of alcohol, add them to a beaker, and stir to form a uniform and transparent solution at room temperature; weigh 0.7 grams of acetylacetone Iron, completely dissolved in 20 ml of deionized water, the solution is a red solution, add it to the above solution, mix and stir for 1 hour, the solution is dark red, add the solution to the lining of a stainless steel autoclave with a capacity of 100 ml, The stainless steel autoclave was sealed and heated to 180 degrees, kept for 10 hours and then cooled naturally, and the red precursor was obtained after centrifugal cleaning with alcohol and deionized water for three times; Under the action of hydrogen and argon gas, the temperature was raised to 350 degrees Celsius at a heating rate of 2 degrees Celsius per minute. After holding for 2 hours, it was cooled to room temperature with the tube furnace; A three-electrode syst...

Description

technical field [0001] The invention relates to a method for preparing deformed cubic Fe 2 O 3 / Fe complex method and compounds prepared by the method. technical background [0002] With the intensification of environmental pollution and energy depletion problems, green and sustainable energy has received widespread attention. Among them, hydrogen energy is a green and sustainable energy source, which can be produced by electrolyzing water. The water electrolysis process is mainly limited by the oxygen evolution reaction. Ruthenium oxide or iridium oxide is a common oxygen evolution electrocatalyst in the industry, but the cost is expensive. Ferric oxide is easy to prepare and low in price, but has poor performance, small electrochemically active area and poor electrical conductivity. Therefore, how to improve the electrochemical active area and conductivity, and improve the catalytic oxygen evolution performance of ferrous oxide electrocatalysts has become a key issue. ...
