Abstract: Provided is an electrode for electrolysis and a preparation method of the same. The electrode for electrolysis has an improved needle-like structure of a rare earth metal compared to conventional electrodes, and thus detachment of catalytic materials is reduced, so that the electrode is excellent in durability such as exhibiting stable performance even in a reverse current flow. Further, since the electrode for electrolysis has a low overvoltage value, an overvoltage required amount of the electrolytic cell can be remarkably reduced. In addition, an electrode for electrolysis having the above effect can be prepared without introducing additional precursors or changing manufacturing facilities.

Abstract: Disclosed is an aerogel for capturing carbon dioxide (CO2 ) and, more particularly an aerogel for capturing CO2 and a preparation method for the same, where the aerogel for capturing CO2 is prepared using a magnesium precursor and an aluminum precursor by an epoxide-driven sol-gel method and a subsequent drying method using supercritical carbon dioxide to have a high CO2 adsorptive performance at elevated temperature. There is provided an aerogel for capturing CO2 to selectively adsorb CO2 at elevated temperature, thereby contributing to the reduction of the CO2 emission that is mainly responsible for atmospheric pollutions by using the high-efficiency aerogel for capturing CO2 with high CO2 selectivity, high CO2 adsorption performance, and good recyclability in the repetitive adsorption-desorption processes.
