dc.description.abstract | The invention of an efficient, recyclable, and affordable daylight induced photocatalyst is highly desirable, for example to enhance the sustainability in industrial sectors requiring wastewater treatments. In the present paper, a facile and inexpensive iodine sublimation process was developed to prepare freestanding and flexible Cu/ Cu2O/CuI sheets to use as daylight photocatalysts capable to degrade toxic pollutants continuously without creating secondary pollution issues. The structural, chemical, and electronic properties of the Cu/Cu2O/CuI nanostructures were systematically investigated. In particular, intriguing hierarchical structures were observed in form of the 20-30 nm CuI nanoparticles self-assembled into the similar to 400-500 nm sized CuI nanoclusters. Indeed, similar to 92% of the Rhodamine B - often referred as RhB - dye degradation was readily achieved, and the efficiency was controlled simply by adjusting the number of sheets used. Importantly, in contrast with the conventional nanoparticle photocatalysts, the free-standing and flexible Cu/Cu2O/CuI sheets demonstrated excellent recyclability and versatility of handling. Moreover, potential mechanisms for suppressing the recombination of the photogenerated carriers were discussed. As a result, combining the fundamental data and the practically achieved results, the freestanding and flexible Cu/Cu2O/CuI nanostructures are suitable candidates for an industrial upscaling as daylight activated photocatalysts for the wastewater treatment. | - |
