Solution-processed Cu2−xO-Fe2O3 composites as novel supercapacitor anodic materials

αFe2O3 and binary composite Cu2−xO-αFe2O3 films were deposited onto fluorine-doped tin oxide glass via a spin spray process at 90 °C. Composite films of varying composition such as αFe2O3 (FC-0), CuO-αFe2O3 (FC-1) and Cu2O-αFe2O3 (FC-2) were prepared by controlling the ion molar ratio of the precurs...

Zusammenfassung:αFe2O3 and binary composite Cu2−xO-αFe2O3 films were deposited onto fluorine-doped tin oxide glass via a spin spray process at 90 °C. Composite films of varying composition such as αFe2O3 (FC-0), CuO-αFe2O3 (FC-1) and Cu2O-αFe2O3 (FC-2) were prepared by controlling the ion molar ratio of the precursor source solution. The FC-0 surface exhibited poor wetting traits toward water (θc > 90°). Conversely, the FC-2 surface displayed good wettability, exhibiting a water contact angle
