摘要

通过 g-C3N4 和 WO3 纳米晶体的定量电泳共沉积,制备出了具有良好机械性能(包括内聚力和对不锈钢支架的附着力)的 g-C3N4 层。典型层面积密度为 0.64 mg cm-2。在蓝光照射下对 4-氯苯酚的光催化降解表明,含有 25-50 wt.% WO3 的稳定复合层的性能仅略低于不稳定的纯 g-C3N4 层。g-C3N4 具有较高的光催化性能,而 WO3 则使复合层在搅拌水中具有良好的机械阻力。最后,复合层在 24 小时内的 4-氯苯酚矿化度高达 75%,甚至高于相应的悬浮液。由于其在水中的稳定性和性能,所开发的层适用于环境技术应用。

Supported g-C3N4/WO3 mixed layers for photocatalytic water remediation

g-C3N4 layers with good mechanical properties, including their cohesion and adhesion to stainless-steel supports, were prepared by the quantitative electrophoretic co-deposition of g-C3N4 and WO3 nanocrystals. It was carried out in a mixture of organic solvents by applying a voltage of 750 V. The typical layer area density was 0.64 mg cm–2. The photocatalytic degradation of 4-chlorophenol under blue-light irradiation showed that the performance of stable composite layers containing 25–50 wt.% of WO3 was only slightly weaker than that of unstable pristine g-C3N4 ones. The high photocatalytic performance was due to g-C3N4, while WO3 contributed to a good mechanical resistance of layers in stirred water. Finally, the composite layers exhibited a very high 4-chlorophenol mineralization of 75% in 24 h, even higher than the corresponding suspensions. Owing to their stability in water and performance, the developed layers are suitable for applications in environmental technologies.
