| 摘要:纤维素高值化利用是传统制浆造纸产业向生物质高效利用综合平台转型升级的关键。纤维素表面上的亲水羟基可通过配位作用和电荷效应促进晶体在其表面的成核生长，是负载无机纳米颗粒的优秀载体。氧化亚铜（Cu2O）是一种具有可见光催化活性、广谱杀菌性能的p型半导体，可应用在传感器、能量储存与转化、抗菌材料等领域。本文介绍了通过水热法、化学液相还原法、电化学沉积法在纤维素上负载Cu2O的研究进展，并总结了Cu2O-纤维素复合材料在光催化降解、抗菌材料和新型织物等领域中的应用，最后对Cu2O-纤维素复合材料的未来发展方向进行了展望。 |
| Abstract:The high-value utilization of cellulose was the key to the transformation and upgrading of the traditional pulp and paper industry to a comprehensive platform for efficient utilization of biomass. The hydrophilic hydroxyl groups on cellulose surface could promote the nucleation and growth of crystals through coordination and charge effects， making cellulose an excellent substrate for loading inorganic nanoparticles. Cu2O was a p-type semiconductor with visible light catalytic activity and broad-spectrum bactericidal properties. It could be used in sensors， energy storage and conversion， antibacterial materials and other fields. The research progress of Cu2O loading on the cellulose by hydrothermal method， chemical liquid phase reduction， and electrochemical deposition were introduced in this paper. The application of Cu2O-cellulose composite materials in the fields of photocatalytic degradation， antibacterial materials and new fabrics was summarized. Finally， the future development direction of Cu2O-cellulose composite materials was prospected. |
