This study aimed to synthesize and characterize calcium oxide (CaO) nanoparticles as a photocatalyst in the degradation process of indigo carmine (IC) dyes. Several steps were carried out to produce CaO nanoparticles by mixing 0.5 M of CaCl2 solution with various NaOH solutions (0.5; 0.8; and 1.0 M). Experimental results showed the prospective control of CaO particle sizes. The experiments also confirmed that the greater concentration of NaOH correlates with the greater yield of nanoparticles produced. The best condition to produce CaO nanoparticles was obtained when using the ratio of CaCl2: NaOH of 1:2. Additional results showed the difficulties in the production of CaO particles in the nanometer size, which is due to the existence of solid agglomeration, giving ideas to the need in putting some additional experimental steps. The photocatalytic degradation studies showed several factors affecting the photoreaction rate, including processing time, catalyst dosage, and dye concentration. CaO nanoparticles had the best performance in catalyzing indigo carmine in 50 minutes, which was shown by the combination of 10 mg of CaO nanoparticles and 80 ppm of dye concentration.

Basella alba aqueous leaf extract was employed for the synthesis of ZnO and Ag/ZnO nanocomposites (NC), eliminating the use of hazardous chemicals. UV‐visible spectroscopic analysis, X‐ray diffraction studies, Fourier transform infrared spectroscopy, field emission scanning electron microscopy, transmission electron microscopy, and X‐ray fluorescence spectroscopic analysis were used to determine the optical properties, crystalline structure, phytoconstituents, surface morphology, and elemental composition of the fabricated nanomaterials. The synthesized NC were employed as antioxidant in order to determine their free radical‐quenching effect. In vitro antibacterial activity assays exhibited their enhanced potential on selective gram‐positive and gram‐negative bacterial pathogens. The Ag/ZnO NC display a rapid catalytic reduction rate for rhodamine B, methylene blue, and methyl orange with degradation rates of 88 %, 90 %, and 92 %, respectively. Thus, an environmentally benign, cost‐effective synthetic methodology is presented for the size‐controlled synthesis of nanomaterials which act as multifunctional platform to alleviate organic pollutants.
