Synthesis, characterization, thermal stability, and application of microporous hyper cross-linked polyphosphazenes with naphthylamine group for CO2 uptake

摘要: There are numerous problems in the world, but environmental pollution is the biggest threat to life. Air pollution is the most critical form of environmental pollution because air is the most essential need of life. However, industrialization, population growth, and fossil fuel use increase hazardous and greenhouse gas concentrations daily. Greenhouse gases like carbon dioxide (CO2) contribute to global warming; hence, efficient, inexpensive, sustainable, and ecologically friendly air purification solutions are required. This study proposed a new method for synthesizing N- and P-rich polyphosphazene-based hyper cross-linked polymer (HCP) for CO2 adsorption. Due to their persistent porosity, low density, and high surface area, hyper cross-linked porous organic–inorganic hybrid phosphorus and nitrogen-rich polymers are cost-effective and promising gas adsorption materials. We synthesized hybrid organic …
