In this work, we have assembled Bi₂WO₆ nanoparticles on the surface of honeycomb-like porous carbon skeleton (PCS) via a hydrothermal route to achieve a new type of [email protected]₂WO₆ hybrid composite photocatalysts. The [email protected]₂WO₆ hybrid structures are determined by SEM, TEM and XPS characterizations. UV–vis DRS investigation suggests an enhanced visible-light absorption of the [email protected]₂WO₆ composites. Transient photocurrent response, EIS and PL spectroscopy characterizations demonstrate that the composites exhibit an efficient separation of photoproduced electron/hole pairs. The photocatalytic performance of the composites were evaluated by using RhB as the model pollutant and simulated sunlight as the light source. It is revealed that the [email protected]₂WO₆ hybrid composites manifest much enhanced photocatalytic performance. The 5 wt%[email protected]₂WO₆ composite manifests the highest photocatalytic activity, which is ca. 2.1 times as large as that of bare Bi₂WO₆ nanoparticles. This can be mainly ascribed to two factors: (1) The photogenerated electron/hole pairs in Bi₂WO₆ are efficiently separated due to the electron transfer between Bi₂WO₆ and PCS; and (2) PCS induces enhanced visible-light absorption and the visible-light-excited electrons in PCS could also take part in the photocatalytic reactions.

在这项工作中，我们通过水热途径将Bi ₂ WO ₆纳米颗粒组装在蜂窝状多孔碳骨架（PCS）的表面上，以实现新型的[受电子邮件保护的] ₂ WO ₆杂化复合光催化剂。[电子邮件保护的] ₂ WO ₆杂化结构通过SEM，TEM和XPS表征确定。紫外可见DRS研究表明，[受电子邮件保护的] ₂ WO ₆具有增强的可见光吸收能力复合材料。瞬态光电流响应，EIS和PL光谱表征表明，该复合材料表现出光生电子/空穴对的有效分离。以RhB为模型污染物，以模拟太阳光为光源，对复合材料的光催化性能进行了评价。揭示了[电子邮件保护的] ₂ WO ₆杂化复合材料表现出大大增强的光催化性能。5 wt％[受电子邮件保护的] ₂ WO ₆复合材料表现出最高的光催化活性，约为。是裸Bi ₂ WO _6的2.1倍纳米粒子。这可以主要归因于两个因素：（1）光生电子/空穴对中的Bi ₂ WO ₆被有效地由于分离的Bi之间的电子转移₂ WO ₆和PCS; （2）PCS诱导增强的可见光吸收，并且PCS中的可见光激发电子也可能参与光催化反应。
