Solar photocatalytic degradation of orange G dye based on zinc oxide / Nur Aisyah Hamzah

Solar photocatalytic was a widely used of energy sources that combine the solar or sunlight and chemical to acquire the chemical reaction The objective of the study are to investigate the degradation of OG under different condition with sunlight and without sunlight as the irradation sources. It...
