A cyclic process for the capture of carbon dioxide (CO2) directly from air utilizing a three-compartment electrolytic cell coupled with a hydroxide-based CO2 capture system as well as a carbonate-based CO2 capture system. Air is passed over a hydroxide compound in the hydroxide-based CO2 capture system to extract carbon dioxide from the air and produce a carbonate compound which is transferred to the carbonate-based CO2 capture system, where air is passed over the carbonate compound to extract carbon dioxide from the air and produce a bicarbonate compound. The bicarbonate is then passed into the three-compartment electrolytic cell where CO2, hydrogen and oxygen gases are separately released and the bicarbonate solution is transformed into a hydroxide solution that is reused in the hydroxide-based CO2 capture system. The flow of input compounds from one system to the other enables efficient operation of the direct air capture of carbon dioxide system.

Provided are a porous catalytic membrane, a membrane electrode assembly and a water electrolysis device. The porous catalytic membrane includes a porous polymer membrane formed by interweaving randomly arranged nanofibers and a catalyst coated on a surface of the nanofibers. The porous polymer membrane has a self-supporting structure and a large specific surface area, providing a large number of loading sites for the catalyst. The catalyst can be directly anchored onto the nanofibers of the porous polymer membrane through a physical or chemical method to achieve uniform dispersion without the need for coating by ionomers, thereby avoiding high costs and performance degradation caused by the adoption of ionomers. The exposure degree of the catalytic active sites is significantly increased, thereby enhancing utilization efficiency of the catalyst and reducing the amount of noble metal catalysts.
