Table 3. Selective Hydrogenation of Different Substrates over 0.43% Au/NiAlO-2-500^a.

^aReaction conditions: p(H₂) = 1.0 MPa; T = 100 °C; catalyst 0.1 g; 4-nitrostyrene 100 μL; toluene 5 mL; stirring speed = 500 rpm; and reaction time 4 h.

^bThe conversion of 4-nitrostyrene and selectivity for the products were determined by GC and GC–MS.

^cReaction time 165 min.

^dOthers include aniline.
