Shape and size effects on photocatalytic hydrogen production via Pd/C3N4 photocatalysts under visible light

Through a combination of operando nuclear magnetic resonance and gas chromatography, the effects of Pd nanoparticles with different crystal planes and sizes on the reduction and oxidation reaction part of the photocatalytic reaction were studied in detail. The results show that the crystal planes affect more to the oxidation production selectivity of the catalyst, and the size affect more to the reaction activity.
