Abstract Carbon dot powders without combining with any nanostructures or nanomaterials exhibit broadband light-absorption ability and they are proved to possess excellent photoreduction performance. Not only do they exhibit highly efficient reduction of quinones under an atmosphere of air and visible light irradiation, but they can be also used repeatedly without incurring obvious changes in photocatalytic activities. Our experimental evidences indicate that photoinduced electron transfer properties of carbon dots endow photoreducing capacities of their powders.

用于光催化还原醌类的碳点粉末

摘要 碳点粉未与任何纳米结构或纳米材料结合，表现出宽带光吸收能力，并被证明具有优异的光还原性能。它们不仅在空气和可见光照射下表现出高效的醌还原，而且它们还可以重复使用而不会引起光催化活性的明显变化。我们的实验证据表明，碳点的光致电子转移特性赋予了其粉末的光还原能力。
