| Abstract: | Mesoporous MoO3 shows an apparent activity in the catalytic hydrogenation of N-ethylcarbazole (NEC), where a significant amount of tetrahydro-N-ethylcarbazole (4H-NEC) and perhydro-N-ethylcarbazole (PNEC) are detected with the hydrogen uptake of 0.97 wt% after 6 h when the temperature rises to 220 °C. 0.5 wt% Pd/MoO3 catalyst shows a superior catalytic efficiency than the traditional precious metal catalysts 0.5 wt% Ru/Al2O3 and 0.5 wt% Pd/Al2O3, especially in the conversion of Octahydro-N-ethylcarbazole (8H-NEC) to PNEC. The hydrogenation mechanism of MoO3 is completely different from the traditional precious metal catalysts. With the presence of a small amount of Pd, the breaking of H | |
