Abstract
A copper oxide thin film was synthesized through a copper sheet annealing process that was carried out using a gas stove, furnace and 1000 W tungsten . The product and its response were measured using a and then characterized by XRD, SEM and EDX. Furthermore, the copper oxide was applied as a photocathode in a cell with Platinum (Pt) as the anode for methyl orange degradation, and the thin film annealed at 60 sec produced the highest current density. According to XRD and EDX results, copper oxide structure was dominated by Cu2O, while SEM showed the presence of a Cu2O porous surface. Methyl orange solution degradation also showed the best result for the copper oxide annealed at 60 sec and in all pH variations, while the best degradation was obtained at pH 1.

Contamination by organic pollutants such as dyes, pesticides, and hazardous toxic chemicals is increasing due to the rapid industrial development Ismail et al (2019); Kasinathan et al (2016); Mageshwari et al (2015); Saikia et al (2015)
Methylene blue and methyl orange are the main ones found in wastewater John et al (2017); Kushwaha et al (2014); Sahu, Satpati, and Mohapatra (2019)
In this research was aimed to utilize the Cu2O (Copper Oxide) thin ilm synthesized from copper sheet through an annealing process as a photocatalyst for methyl orange degradation
Summary
Contamination by organic pollutants such as dyes, pesticides, and hazardous toxic chemicals is increasing due to the rapid industrial development Ismail et al (2019); Kasinathan et al (2016); Mageshwari et al (2015); Saikia et al (2015). Organic dyes are one of the main sources of industrial wastewater. Methyl orange (MO) is an intensely colored toxic compound used in textile industry. It changes from red (at pH 3.1) to orange-yellow (at pH 4.4) John et al (2017). A number of physical and chemical techniques have been reported for the removal of dye compounds such as adsorption, biodegradation, ozonation, iltration, coagulation and advanced
