The synthesis of the photocatalysts involved a meticulous procedure utilizing olive oil as a precursor. Characterization studies employing transmission electron microscopy (TEM), X-ray diffractometer (XRD), and Brunauer-Emmett-Teller (BET) surface area confirmed the successful synthesis of the composite photocatalysts with well-dispersed nanoparticles and varying surface areas. Photocatalytic degradation experiments revealed that Mn-doped CdS@CQDs exhibited the highest degradation efficiency for both MB and RB5 under optimized reaction conditions, with pH identified as the most significant parameter, and statistical analyses supported the validity of the experimental data. Based on the results, the highest MB degradation efficiency (99.87%) was achieved at the following reaction conditions: pH = 9, catalyst amount = 0.55 g/L and initial hydrogen peroxide concentration (HPC) = 1 mM while the highest RB5 degradation efficiency (98.15%) was obtained at the following reaction conditions: pH = 3, catalyst amount = 1 g/L and HPC = 0.55 mM. Comparison with the literature showcased the competitive performance of the synthesized photocatalysts, achieving higher efficiencies with lower amounts of photocatalysts and hydrogen peroxide. Kinetic studies revealed that the first-order reaction kinetic was observed in both MB and RB5 degradation.

The bioaugmented ZnO-NPs have been manufactured by Uziza seed extract using zinc acetate dihydrate as the precursor and sodium hydroxide with calcination. The hexagonal/spherical crystalline structure at high purely with a mean size of 7.39 nm was confirmed via XRD and SEM analyses of ZnO-NPs. A strong absorption peak at about 350 nm, specific for ZnO-NPs, was observed by a UV-visible spectrometer. The optical bandgap of ZnO-NPs was estimated as about 3.58 eV by the Kubelka-Munk formula. FTIR findings indicated the presence of biofunctional groups responsible for the bioreduction of bulk zinc acetate to ZnO-NPs. The growth rates of E. coli (ATCC 25,922) significantly decreased with ZnO-NPs exhibited compared to the controls.

Comparative analyses were conducted between formulations incorporating micronized pumice and the standard ceramic tile recipe.

These included viscosity, sieve residue, green strength pre-firing, firing shrinkage, water absorption, firing strength, and firing color after-firing. The results indicated that the samples incorporating micronized pumice closely matched the physical and mechanical properties of the standard porcelain tile. Phase and microstructural analyses revealed the presence of mullite and quartz phases. Notably, micronized pumice demonstrated promise as a substitute for clay or feldspar, with the optimal usage rate determined to be 7% in the porcelain tile recipe.
