主　　题：solvothermal process indium oxide noble metal H2 sensor 

摘      要：Nanocrystalline In_2O_3 was synthesized through a controllable solvothermal process in one-step at 210℃for 24 h. Gas sensing properties were tested by mixing gas in air in static *** 268.5℃,the nanocrystal showed high sensitivity to LPG but lower sensitivity to H_2 and *** order to enhance the sensitivities to H_2 and CO,0.5 mass % Au and Pd were doped by an impregnation *** sensitivities to H_2 and CO were increased under different working ***-doped In_2O_3 was superior to Pd-doped In_2O_3 whatever to H_2 or CO;the sensitivity was increased with the increase of working temperature;gas sensing properties to H_2 overmatched to CO.
