Abstract: Strontium doped Nickel hydroxide (Sr/Ni(OH2) nanoparticles, pure NiO were
synthesized by co-precipitation method with the use of NiCl2.6H2O, Sr(NO3)2 for Nickel and Strontium sources, respectively. NaOH used as a precipitating agent. The impact of Sr doping agent on both morphological and characteristics of nanoparticles was investigated using XRD, SEM, and FTIR methods. The co-precipitation approach was the most efficient and cost effective way to synthesize nanoparticles. Sr/Ni(OH)2 was synthesized at a low temperature and is employed in photo-degradation applications. The photo-catalytic degradation of dyes has been investigated all throughout the world, independent of national scientific standards. Common factors to mention for degradation investigations are dye content, oxidizing species concentration, catalyst employed, strength, and photon source. The synthesized NiO,
Sr/Ni(OH)2 served as an effective catalyst for the photo-degradation of Fast green (FG) dye. Photo-catalytic degradation of rapid green dye used first-order kinetics, and dye degradation produced the greatest results. The photo-degradation efficiency of the rapid green dye was around 50.64% for NiO and 95.2% for the produced Sr/Ni(OH)2 catalyst. The kinetic data collected during the decolorization of the fast green dye were examined.
