Abstract

The invention discloses a method or electric field-induced conversion of water and CO2 to an organic polymer. The method is characterized in that the method comprises the following steps: dissociating water by using the induction effect of an electric field with water and CO2 as base raw materials and an electric field induced reactor as a reaction device to generate hydrogen free radicals and hydroxy free radicals; converting the hydroxy free radicals with transition metal ions as a catalyst to form water and oxygen; and reacting water with CO2 in an aqueous solution system to generate carbonic acid, reacting carbonic acid with the hydrogen free radicals to generate oxalic acid, and continuously reacting oxalic acid and its derivative with the hydrogen free radical reaction to generate the organic polymer. The method can substantially improve the production efficiency and rate of the hydrogen free radicals, generates a large quantity of the hydrogen free radicals, greatly improves the artificial photosynthesis efficiency, and promotes the synthesis of carbohydrate and the organic polymer with complex structure.

Description

technical field [0001] The present invention relates to the fields of electrochemistry and artificial photosynthesis, in particular to an electric field induced water and CO 2 Methods of conversion into organic polymers. Background technique [0002] With the development of society, the human demand for energy continues to increase, and the consumption of petroleum products and coal fuels increases year by year. The massive burning of oil, natural gas and coal, resulting in atmospheric CO 2 concentration increased year by year. CO 2 The increase in concentration leads to the global warming effect. Every 100 years, the maximum temperature rises by 0.82°C, the minimum temperature rises by an average of 1.79°C, and the average temperature rises by 0.79°C. The earth's gasification and warming lead to the melting of icebergs in the north and south poles, rising sea water levels, causing natural disasters such as hurricanes, heavy rains and tsunamis, and increasing the occurre...
