Key Points

To investigate how varying pulse repetition frequency affects the synthesis of platinum nanoparticles.
Synthesis of platinum nanoparticles using H2PtCl6 ⋅6H2O solution
Variation of pulse repetition frequency below 100 Hz
Measurement of particle formation rates
Increased pulse repetition frequency accelerates reaction up to 100 Hz
Effect saturates at higher frequencies
Reduced per-pulse efficiency at elevated frequencies observed

Abstract

Platinum (Pt) nanoparticles were synthesized by laser-induced reduction from a H2PtCl6 ⋅6H2O solution. The reaction accelerated dramatically with increasing pulse repetition frequency below 100 Hz. However, the effect saturated at higher frequencies, possibly due to reduced per-pulse efficiency.
