PdGa/TiO2an efficient heterogeneous catalyst for direct methylation of N-methylaniline with CO2/H2

PdGa/TiO₂showed excellent catalytic performance in the methylation of amine with CO₂/H₂as the PdGa bimetallic particles formed on the surface of TiO₂, which could activate CO₂to form formic acid, an important and active methylation reagent.
