Synthesis and spectroscopic characterization of palladium-doped titanium dioxide catalyst

In this work, we reported synthesis of palladium (Pd)-doped titanium dioxide (TiO2) (Pd-TiO2) nanoparticles by the sol-gel-assisted method. The synthesized Pd-doped TiO2 nanoparticles were characterized using X-ray diffraction, transmission electronic microscopy, energy-dispersive spectroscopy, Fourier transform infrared (FT-IR) spectroscopy and voltammetry techniques. The analysis showed that particles are spherical in shape and pure anatase form with average size about 10 nm. To investigate the catalytic efficiency of Pd-TiO2 nanoparticles, the hydrogen evolution reaction using the deposited film of Pd-TiO2 nanoparticles on glassy carbon electrode (Pd-TiO2/GCE) was studied in 0.1 M H2SO4 solution using linear scanning voltammetry. This study demonstrates the feasibility of using gelatin for the synthesis of Pd-TiO2 catalyst.
