Puntos clave

To investigate the effects of photothermal flash light annealing on the doping of strontium titanate nanoparticles and their photocatalytic performance.
Doped SrTiO3 nanoparticles with Rh and La using photothermal flash light annealing within 10 seconds.
Conducted photocatalytic performance tests comparing FLA-doped samples with those doped via thermal annealing.
FLA-doped SrTiO3 nanoparticles demonstrated superior photocatalytic performance compared to reference samples.
Improvements were observed in photocatalytic efficiency due to rapid doping process.

Resumen

The surface doping of SrTiO 3 nanoparticles with Rh and La is realized within 10 s by photothermal flash light annealing (FLA). In photocatalytic performance tests, samples doped by FLA outperform various reference samples doped by thermal annealing.
