摘要
光催化技术在解决能源短缺和环境污染等方面具有巨大潜力.如何提高光催化材料的太阳光利用效率和催化活性是制约光催化技术能否大规模应用的关键问题.自然界的植物和藻类等生物历经千百万年自然选择的残酷竞争,已进化出了能有效捕捉、吸收和利用太阳光的特殊结构和环境净化功能.利用这些自然界中具有特殊光学性质或能有效吸收和利用太阳光的结构或物质制备光催化剂,有望突破传统合成光催化剂的技术局限,开辟高效光催化剂合成的新途径.文章从形貌复制与调控、元素自掺杂、光敏材料、硫化物半导体、生物碳复合材料等方面详细介绍了仿生材料在光催化中的应用,希望对设计、制备高效光催化材料提供一定的理论参考和借鉴意义.
Photocatalysis technology has great potential in solving energy shortage and environmental pollution.How to improve the utilization efficiency and catalytic activity of photocatalytic materials is a key problem that restricts the application of photocatalytic technology.In nature,plants,algae and other organisms have evolved special structures and environmental purification functions that can effectively capture,absorb and utilize sunlight through the cruel competition of natural selection for millions of years.It is expected to break through the technical limitations of traditional photocatalyst synthesis and open up a new way of high efficiency photocatalyst synthesis by using those structures or substances which have special optical properties in nature or can effectively absorb and utilize sunlight.In this paper,we introduced the application of biomimetic materials in the study of photocatalysis from the aspects of morphology replication and regulation,element self-doping,photosensitive materials,sulfide,biological carbon materials and so on.We hope to provide some theoretical reference for the design and preparation of efficient photocatalytic materials.
