Description

<jats:title>Abstract</jats:title> <jats:p>Catalytic methylation of benzene using CO2/H2 was investigated using various combinations of supported metal catalysts and zeolites in a batch reactor. After a thorough catalyst screening process, the combination of Pt(3)/MoOx(30)/TiO2 and H-MOR (SiO2/Al2O3 = 90) was the most efficient, achieving up to 39% benzene-based yield and 27% CO2-based yield, without promoting the dearomatization of benzene, under the reaction conditions employed in this study (1 MPa CO2, 5 MPa H2, 1 mmol of benzene, 240 °C, 12 h).</jats:p>
