In this work, a patterned reduced graphene oxide (RGO)/silver nanoparticles on Al sheet was prepared using layer-by-layer assembly technique. The morphology, structure and composition of the Al/RGO/Ag were investigated using SEM, XRD and XPS. It showed that there existed a strong interaction among Al, the patterned reduced graphene oxide and Ag nanoparticles in the Al/RGO/Ag sheet, which made the patterned Al/RGO/Ag sheet be as a sensitive SERS material for rapidly monitoring trace malachite green with good reproducibility and high stability. Also, the plug and play Al/RGO/Ag sheet exhibited high and stable catalytic degradation activity for malachite green. The constructed bifunctional sheet will provide some references for designing those materials used in detection and degradation of contaminants in wastewater.
