Defect Analysis and Testing of Low Power Nanoscale Reversible Decoder using Quantum Dot Cellular Automata

Abstract

The photocatalytic activity of graphene oxide (GO) and zinc oxide composite was explored. The composites were prepared in three different ratios: GO:ZnO (1:1), (1:2) and (2:1) by mechanochemical method (grinding) of the two components. Graphene oxide was synthesized by three different methods namely Hummer's, modified Hummer's and Tour's method. It was observed that composite of GO-ZnO (2:1) gave better results. The photocatalytic efficiency of the composite was evaluated using Victoria blue B as a model pollutant. It was found to be even better than zinc oxide. The reusability of the composite was also confirmed.
