Preparation of Manganese Oxide Porous Nanostructures using Amino-acid and its Selective C 3 H 8 Sensing Properties

Porous manganese oxide porous nanostructures were prepared by amino-acid-mediated solvothermal self assembly reaction and subsequent heat treatment at . When Mn-precursors were heat-treated at , the sensors did not show significant gas responses. In contrast, the manganese oxide heat-treated at showed the significant gas responses, that is, the resistance decrease to 100 ppm (
