Abstract

During the past two decades, immobilization of titanium dioxide (TiO2), a well-known photocatalyst, on several polymeric substrates has extensively gained ground since it limits the need of post-treatment separation stages. Taking into account the numerous substrates tested for supporting TiO2 photocatalysts, the use of biodegradable polymer seems a hopeful option owing to its considerable merits, including the flexible nature, low price, chemical inertness, mechanical stability and wide feasibility. The present review places its emphasis on recently published research articles (2011–2021) and exhibits the most innovative studies facilitating the eco-friendly biodegradable polymers to fabricate polymer-based photocatalysts, while the preparation details, photocatalytic performance and reuse of the TiO2/polymer photocatalysts is also debated. The biodegradable polymers examined herein comprise of chitosan (CS), cellulose, alginate, starch, poly(lactid acid) (PLA), polycaprolactone (PCL) and poly(lactide-co-glycolide) (PLGA), while an emphasis on the synthetical pathway (dip-coating, electrospinning, etc.) of the photocatalysts is provided.

生物可降解聚合物负载二氧化钛光催化剂在环境修复中的应用

在过去的二十年中，二氧化钛(TiO2)是一种众所周知的光催化剂，由于它限制了对后处理分离阶段的需求，因此在几种聚合物基质上的固定化得到了广泛的应用。考虑到用于支持TiO2光催化剂的众多衬底，使用生物可降解聚合物似乎是一个有希望的选择，因为它具有相当大的优点，包括灵活的性质、低廉的价格、化学惰性、机械稳定性和广泛的可行性。本文综述了近年来发表的研究文章(2011-2021)，展示了最具创新性的研究成果，促进了生态友好的可生物降解聚合物制备聚合物基光催化剂，同时对TiO2/聚合物光催化剂的制备细节、光催化性能和再利用进行了讨论。本文研究的生物可降解聚合物包括壳聚糖(CS)、纤维素、海藻酸盐、淀粉、聚乳酸(PLA)、聚己内酯(PCL)和聚乳酸-共乙醇酸酯(PLGA)，并重点介绍了光催化剂的合成途径(浸涂、静电纺丝等)。
