Abstract

In this study, a series of hybrid nanostructured photocatalysts P25/(NH)WO nanocomposites with the average crystallite size of P25 and (NH)WO of the sample was calculated to be about 30 nm and 130 nm, were successfully synthesized via a simple one-step hydrothermal method. The as-obtained samples was characterized by transmission electron microscopy (TEM), which implies that the P25/(NH)WO nanocomposites are fabricated with favourable nanosizd interfacial. The XPS results confirmed that the obtained sample consists of mixed chemical valences of W and W, the low-valance W sites could be the origin of NIR absorption. As revealed by optical absorption results, P25/(NH)WO nanocomposites possess high optical absorption in the whole solar spectrum of 200-2500 nm. Benefiting from this unique photo-absorption property and the synergistic effect of P25 and (NH)WO, broad spectrum response photocatalytic activities covering UV, visible and near infrared regions on degradation of Rhodamine B have been realized by P25/(NH)WO nanocomposites. Meanwhile, the stability of photocatalysts was examined by the XRD and XPS of the photocatalysts after the reaction. The results show that P25/(NH)WO photocatalysts has a brilliant application prospect in the energy utilization to solve deteriorating environmental issues.

摘要

在这项研究中，通过简单的一步水热法成功合成了一系列具有平均粒径约为 30nm 和 130nm 的 P25/（NH）WO 纳米复合光催化剂。所得样品通过透射电子显微镜（TEM）进行了表征，表明 P25/（NH）WO 纳米复合材料是用有利的纳米级界面制造的。XPS 结果证实，所获得的样品由 W 和 W 的混合化学价组成，低价 W 位可能是近红外吸收的来源。如光吸收结果所示，P25/（NH）WO 纳米复合材料在 200-2500nm 的整个太阳光谱中具有高的光学吸收。受益于这种独特的光吸收特性以及 P25 和（NH）WO 的协同作用，P25/（NH）WO 纳米复合材料实现了对罗丹明 B 的降解的宽光谱响应光催化活性，涵盖了 UV、可见和近红外区域。同时，通过反应后光催化剂的 XRD 和 XPS 对光催化剂的稳定性进行了检验。结果表明，P25/（NH）WO 光催化剂在解决日益恶化的环境问题的能源利用方面具有广阔的应用前景。
