This dissertation also studied the direct synthesis of H_2O_2 from H_2 and O_2 undernormal pressure over polyoxometalates-supported Pd catalysts in the absence of anyliquid acid or halide additives in the liquid phase.

Experimental study on Pd catalysts for purification of vehicle exhaust gas;

Among the methodologies of synthesizing indoles,because of the virtue of Pd catalysts,such as mild reaction condition,high activity,good selectivity,they are usually employed to synthesize indoles.
