In this study, Cu2O thin film covering on a carbon network (CNW) was designed as composite structure with novel flexible characteristics. P-type Cu2O thin film with dominated (111) orientation was successfully deposited on the surface of the CNW via an electrochemical method. The CNW/Cu2O composite exhibits interesting tensile property and high photodegradation efficiency for methyl orange (MO) solution. Its recyclability is highly attractive in potential application in solving azo dye pollution problem.
