Advanced oxidation processes (AOPs) have been extensively investigated on catalytic degradation of organics to carbon dioxide as well as synthesis of macromolecules via free radical-initiated polymerization (RP-AOPs). More recently, nonradical oxidation pathways have been reported in AOPs, which can also trigger polymerization (NRP-AOPs) with high selectivity due to the mild oxidative potential and favorable reaction pathways. In this perspective, we present the advances in RP/NRP-AOPs for innovative polymer manufacture for carbon recycling and classify the polymerization of various monomer compounds, including phenolic, aniline, thiophene, and vinyl monomers. The origins and pathways of polymerization reactions are discussed. We particularly highlight the recent discoveries of NRP-AOPs and the reaction parameters of RP/NRP-AOPs to synthesize various value-added polymers in water, featured by an easy-to-handle system with mild reaction conditions and low chemical input, providing instructional strategies to prepare the value-added polymers from organic wastes to minimize carbon footprint and achieve a circular economy.

用于碳回收的自由基/非自由基高级氧化工艺的挑战

高级氧化过程(AOPs)已被广泛研究用于催化降解有机物为二氧化碳以及通过自由基引发聚合(RP-AOPs)合成大分子。最近,在 AOPs 中报道了非自由基氧化途径,由于温和的氧化电位和有利的反应途径,它也可以以高选择性触发聚合 (NRP-AOPs)。从这个角度来看,我们介绍了 RP/NRP-AOP 在用于碳回收的创新聚合物制造方面的进展,并对各种单体化合物的聚合进行分类,包括酚醛、苯胺、噻吩和乙烯基单体。讨论了聚合反应的起源和途径。
