摘要:

碳氣凝膠是一類密度極低且具有豐富多孔結(jié)構(gòu)的新型材料。國內(nèi)外學(xué)者圍繞碳氣凝膠及其復(fù)合材料的設(shè)計制備和環(huán)境應(yīng)用開展了大量的研究工作。梳理總結(jié)了碳氣凝膠及其復(fù)合材料應(yīng)用于環(huán)境治理的最新進展，包括吸附去除污染物、油水分離和催化降解污染物，闡述了碳氣凝膠及其復(fù)合材料組成、結(jié)構(gòu)和性能之間的關(guān)系，分析材料對不同污染物的吸附、吸收和降解機制，梳理總結(jié)了現(xiàn)有材料的優(yōu)缺點。未來研究的重點方向包括：進一步優(yōu)選低成本的有機固體廢棄物作為制備材料的碳源，發(fā)展低成本、規(guī)模化的材料制備方法；定向調(diào)控材料組成、結(jié)構(gòu)和活性位點進而提升其性能和可循環(huán)性；結(jié)合全面的經(jīng)濟技術(shù)分析和環(huán)境影響評價，將碳氣凝膠及其復(fù)合材料推廣應(yīng)用到大氣、土壤和水體污染的修復(fù)。

Abstract:

Carbon aerogel is a new kind of materials with extremely low density and abundant porous structure. The researchers have conducted numerous studies on the design, preparation and environmental applications of carbon aerogels and their composites. This review gives an overview on the recent advances of environmental applications of carbon aerogels and their composites, including adsorption of pollutants, separation of oils from water as well as catalytic degradation of pollutants. We also summarize the relationships between the composition, structure and property of carbon aerogels and their composites and elucidate the mechanism of adsorption, absorption and catalytic degradation, as a useful reference for subsequent studies. The future research directions include：screening low-cost organic solid wastes, establishing low-cost, large�瞫cale and controlled preparation method, improving performance and recyclability via tuning composition and structure, conducting comprehensive economic-technical analysis and environmental assessment and then promoting the remediation of actual atmosphere, water and soil pollutions.
