Rising health issues of Worldwide pollution by fossil fuel products are Fostering the development of safer materials such as biopolymers in many sectors such as food, pharmaceutical, medical and environmental industries. Indeed, biopolymers are often safe, biodegradable, cheap and easy to modify. Here we review photocatalysts based on polysaccharides for wastewater treatment. Polysaccharides include starch, cellulose, carrageenan, alginate, chitin, chitosan and gum. The main reasons for using biodegradable biopolymers are their ability to adsorb pollutants and to be modified with nanoparticles and semiconductors.

多糖基生物聚合物作为载体在水和废水光催化处理中的应用：综述

全球范围内化石燃料产品污染日益严重的健康问题正在促进食品、制药、医疗和环境行业等许多领域的生物聚合物等更安全材料的开发。事实上，生物聚合物通常是安全的、可生物降解的、便宜的且易于改性。在这里，我们回顾了基于多糖的光催化剂用于废水处理。多糖包括淀粉、纤维素、角叉菜胶、藻酸盐、甲壳质、壳聚糖和树胶。使用可生物降解的生物聚合物的主要原因是它们能够吸附污染物以及用纳米颗粒和半导体进行改性。
