Key Points

The aim is to understand the geometry of aniline's adsorption during co-adsorption with hydrogen over Pd/Al2O3 catalysts.
Used infrared spectroscopy to analyze the adsorption behavior.
Experiment involved co-adsorption of aniline and hydrogen.
Focused on a 5 wt% Pd catalyst supported on alumina.
Identified the specific geometry of the aniline adsorption complex.
Showed that the presence of hydrogen influences aniline selectivity in hydrogenation.
