摘要: The conversion efficiency of existing photocatalysts may decrease with increasing humidity level. The photocatalyst of this invention is made be first mixing an alcohol, a titanium alkoxide and a binder in the presence of a catalytic acid to form a mixture. This mixture is then heated at about 100° C. for at least 2 hours, and then calcinated at about 450° C. for at least 2 hours. The resulting catalyst is found to have improved efficacy at high humidity level.

摘要: A gas sensor may include a mat including nanofibers attached to a substrate layer, a first electrode in electrical communication with one end of the mat, and a second electrode in electrical communication with the other end of the mat. The sensitivity of the gas sensor for carbon monoxide at a concentration of 50 ppm in air, and at a temperature from about 20° C. to 26° C., is at least 1.29.
