- Abstract
- Mesoporous metal oxides exhibit excellent physicochemical properties and are widely used in various fields, including energy storage/conversion, catalysis, and sensors. Although several soft-template approaches are reported, high-temperature calcination for both metal oxide formation and template removal is necessary, which limits direct synthesis on a plastic substrate for flexible devices. Here, a universal synthetic approach that combines thermal activation and oxygen plasma to synthesize diverse mesoporous metal oxides (V2O5, V6O13, TiO2, Nb2O5, WO3, and MoO3) at low temperatures (150-200 degrees C), which can be applicable to a flexible polymeric substrate is introduced. As a demonstration, a flexible micro-supercapacitor is fabricated by directly synthesizing mesoporous V2O5 on an indium-tin oxide-coated colorless polyimide film. The energy storage performance is well maintained under severe bending conditions.
The synergistic effect of thermal activation and plasma enabled low-temperature synthesis (150-200 degrees C) of various mesoporous metal oxide (V2O5, V6O13, TiO2, WO3, Nb2O5, and MoO3), suitable for flexible polymeric substrates. As a proof of concept, the direct synthesis of mesoporous V2O5 is demonstrated on an indium-tin oxide-coated polyimide film and its application as electrode materials.image
