Abstract Pure and different percentages (0.25, 0.5, 1.0, 2.5%) of silver (Ag) doped hydroxyapatites (Hap) were synthesized employing the wet chemical precipitation method. The samples characterized with aid X‐ray diffraction (phase analysis, crystallographic characterization, crystal size calculation using Scherrer equation models), scanning electron microscopy, optical bandgap energy. Hap containing 0.25% Ag showed better photocatalytic activity in various dye concentrations, catalyst doses, pH.

This study investigates the influence of atomic radii copper, cobalt, and cadmium on photocatalytic activity anatase TiO2 xerogels synthesized via solgel method. All samples were annealed at 550 °C for 20 min crystallized into pure phase, as confirmed by XRD Raman spectroscopy. Dopant incorporation matrix reduced grain size (from 24.01 to 9.78 nm) decreased bandgap energy 3.44 3.19 eV). Photocatalytic degradation methylene blue (MB) revealed enhanced doped samples, with rates increasing from 71.65% undoped TiO 79.29%, 86.54%, 94.13% 2 at. % Cu-TiO2, Co-TiO2, Cd-doped TiO2, respectively. Among dopants, Cd-TiO2 exhibited highest efficiency fastest rate. Furthermore, sample demonstrated excellent stability, retaining more than 90% its over six cycles only a 4% loss in capacity.
