Porous manganese oxide porous nanostructures were prepared by amino-acid-mediated solvothermal self assembly reaction and subsequent heat treatment at 600℃. When Mn-precursors were heat-treated at 400 - 550℃, the sensors did not show significant gas responses. In contrast, the manganese oxide heat-treated at 600℃ showed the significant gas responses, that is, the resistance decrease to 100 ppm C_3H_8 (R_a/R_g = 2.17, R_a : resistance in air, R_g : resistance in gas) and the resistance increase to 100 ppm C_2H_5OH (R_g/R_a = 1.92). The opposite change of resistance upon exposure to C_3H_8 and C_2H_5OH was discussed in relation to the mixed phases of manganese oxides with different valences.
