An ultra-fast synthesis of 13X@NaA composites through the plasma treatment for high selective carbon capture

Abstract

The primary challenge in material design and fabrication is achieving excellent performance, economical substances, fast and convenient synthesis for real world applications. We tackle this challenge by an ultra-fast synthesis of core-shell 13X@NaA zeolite composites within only 30 min. By using the plasma treatment, more silanol groups on the surface of 13X powders and hydroxyl radicals in NaA precursor gel result in the accelerated formation of NaA crystal shell. After the potassium ion exchange in different degrees, the obtained 13X@NaKA composites exhibit extremely high selectivity of CO2 over N2 of 149~380 and maintain good capacity of 3.41~1.84 mmol·g-1. Our work provides a promising approach for synthesis of core-shell zeolite composites as economic materials for further multiple applications.
