📄 Abstract（原文）
The present study employs density functional theory to investigate the noncovalent catalysis by chitosan for the conversion of CO2 and NH3 to urea, addressing the pressing need for carbon capture and utilization by converting captured CO2 from industrial sources into a renewable C1 feedstock, specifically urea, which is known for its high nitrogen content as a fertilizer. The conversion of CO2 into urea is crucial to modern agriculture, providing a highly efficient and cost-effective means of supplying the nitrogen required to nourish the global population. Computational quantum chemical calculations elucidate the reaction mechanism, detailing all relevant intermediates and transition states. The findings reveal that the NH2 and OH functional groups of chitosan play a critical role in the reaction by stabilizing key transition states through noncovalent interactions, thereby substantially lowering the overall activation energy barrier. The current study provides significant molecular-level insights into the mechanism underlying chitosan’s noncovalent catalytic properties, establishing a robust foundation for understanding its potential applications as an effective, environmentally sustainable approach to urea synthesis. This work marks a significant advancement in green catalysis, aligning with UN Sustainable Development Goals (SDG) 13 (Climate Action) by using CO2 as a feedstock, SDG 9 (Industry, Innovation, and Infrastructure) by providing a sustainable industrial alternative, and SDG 12 (Responsible Consumption and Production) by demonstrating a circular-economy model valorizing biowaste. These findings pave the way for future experimental validation and the development of biopolymer catalysts, contributing to a more sustainable chemical industry.
