The as-synthesized materials were characterized and tested for their anticancer, anti-inflammatory, and antioxidant activities. The anti-cancer activity of P-g-CN NBs exhibited lower cytotoxicity and higher cell viability than undoped g-CN in HeLa cells using the MTT assay.

In this work, nanostructured composite films of Carbon (Soot) and TiO<sub>2</sub> are fabricated through a custom-made aerosol flame synthesis (AFS) reactor using a facile one-step synthesis technique with good control over nanostructure, crystallinity, defect chemistry and carbon component inclusions. Scanning mobility particle sizer (SMPS) was employed to analyze particle size distribution in the flame.

The 20 %-AgI@PbBiO<sub>2</sub>Br presented the best photocatalytic performance of all the catalysts prepared. The rhodamine B (RhB) molecules were significantly reduced within 70 min (98.72 %), showing a much higher degradation efficiency than bare AgI (73.58 %) and PbBiO<sub>2</sub>Br (46.77 %) under the same conditions.

In addition, the antibacterial efficacy of 20 %-AgI@PbBiO<sub>2</sub>Br against E. coli and S. aureus reaches about 99.99 %. The improved photodegradation efficacy of AgI@PbBiO<sub>2</sub>Br is owing to the construction of a heterojunction between AgI and PbBiO<sub>2</sub>Br, which increases effective charge separation and visible light absorption, thus enabling the decomposition of pollutants. Cycling experiments confirmed the stability and reusability of the material, demonstrating exceptional photocatalytic durability.

More importantly, rare-earth doping significantly elevates both the formation energies and migration barriers of halide vacancies, effectively reducing defect mobility. Specifically, the defect formation energy increases by ∼0.10 eV, and the migration barrier rises by over 0.50 eV.
