研究目的
To engineer the properties of the Nb2O5-ZnO nanostructures which can offer new optical and electrical behaviors and also lead to large surface area.
研究成果
Novel Nb2O5-ZnO nanostructures were synthesized via dual synthesis techniques. The properties were engineered by varying the hydrothermal temperature, affecting the compactness of ZnO growth and the intensity of wurtzite peak. The optical band gap of nanoporous Nb2O5 was reduced when undergoing hydrothermal ZnO at RT and increased with higher hydrothermal temperatures. These nanostructures possess a high surface area to volume ratio, making them suitable for applications such as sensing layer, photocatalyst, and photoanodes.
研究不足
