The catalytic performance evaluation of the catalysts was carried out in a fixed bed reactor (inner diameter =8 mm). Typically, 0.8 g of catalyst was reduced in-situ at atmospheric pressure in a pure H2 atmosphere at 400 °C for 4 h. Then, after the reactor was cooled to 150 °C, the mixture gas (24% CO2/73% H2/3% N2) and toluene were introduced. The catalytic test was performed at 320 °C, 2.0 MPa, 3000 mL•gcat - 1 •h -1 , and toluene weight hourly space velocity (WHSVtoluene) of 0.4 h -1 . The tail gas was analyzed by an online gas chromatography (GC7890B, Agilent) equipped with two thermal conductivity detectors (TCD) and one flame ionization detector (FID). The oil product was gathered by a cold trap and analyzed by an off-line gas chromatography (GC2010, Shimadzu) equipped with an FID and a PONA capillary column. The carbon balance of the products in all catalytic runs were above 95%.
