Abstract

An effective approach to the COS capture and fixation using the alcohol-amine binary systems contained Ethylene Glycol-based polyols (EGs) and Ethylenediamine-based polyamines (EDAs) under ambient conditions is developed. Fourier-Transform Infrared spectroscopy (FTIR), X-ray Photoelectron Spectroscopy (XPS) and X-Ray powder Diffraction (XRD) analyses reveal that COS is converted into thio-alkylcarbonate salts with the special chemical structures of [+H3NR1NH3+-OC(=S)OR2(R3)O(S=)CO-]n, which are named as a COS-Storage Material (COSSM). Notably, the COSSM is successfully applied to the synthesis of CdS Nano-Particles (NPs) for the photocatalytic conversion of CO2 to CO and CH4, and used as a nitro-sulfur compound fertilizer to promote plant growth. Our work has provided a readily available strategy for the green storage and sustainable utilization of COS.
