Unveiling Hierarchical Dendritic Co3O4–SnO2 Heterostructure for Efficient Water Purification

“…Among the studied semiconductor photoelectric materials, Co 3 O 4 and SnO 2 are worthy of our attention because of their excellent optical and electrical properties in photocatalysis/electrocatalysis field applications, , such as transparent electrodes, gas sensors, supercapacitors, photocatalysts, and lithium-ion batteries . Our previous research has pointed out that Co 3 O 4 nanowire is suitable for basic materials of semiconductor heterostructures because nanowire morphology possesses large surface-to-volume ratios, better light trapping, enhanced charge separation efficacy, and a large surface area. − It should be noted that the morphology flexibility of SnO 2 (including nanorods, nanoribbons, nanotubes, nanosheets, hollow spheres, and nanoflowers) renders SnO 2 a suitable platform to interface with other materials into a functional device. The application of Co 3 O 4 /SnO 2 to construct integrated nanohybrids with targeted functionalities hardly found in the individual components for a PEC process is an exciting idea.…”
