TL;DR
Scientists developed a new catalyst to create porous polymer materials that efficiently capture CO2, helping reduce greenhouse gas emissions.
Contribution
A novel oxovanadium(IV) catalyst was developed for synthesizing functional CO2 sorbent materials with high efficiency.
Findings
Oligo(3-buten-2-ol) showed high CO2 sorption (0.82 mmol g–1) and a heat of adsorption of 8.51 kJ mol–1.
The new oxovanadium(IV) catalyst demonstrated high activity in polymerizing olefins and polar monomers.
The stability constant of the complex formation was determined as log β1210 = 27.82.
Abstract
The challenge of ever-increasing greenhouse gas emissions correlates with intensive research into the development of new CO2 sorbents. The research aimed to propose a new generation of porous polymer sorbents that contribute to decarbonization. Among all oligomers and (co)polymers, the 3-buten-2-ol oligomer showed the highest CO2 sorption properties (0.82 mmol g–1). The heat of adsorption of CO2 by oligo(3-buten-2-ol) was equal to 8.51 kJ mol–1. Polyolefins and polar oligomers were synthesized using a new, innovative, and highly active oxovanadium(IV) precatalyst. An easy, one-step method for the synthesis of cis/trans-[VO(acac)2(3-ppy)] provides a unique coordination compound containing two molecules that are reciprocal geometric isomers with a spatial arrangement of acetylacetonate ligands (cis and trans). The complex shows very active catalytic properties in the polymerization…
