研究目的
Investigating the use of green synthesized plasmonic nanostructures decorated TiO2 nanofibers for photoelectrochemical hydrogen production.
研究成果
The study demonstrates the successful synthesis of low-cost, environmentally friendly, green synthesized plasmonic Ag/Au nanostructures decorated TNF as efficient photoanodes for photocatalytic and PEC water splitting. The photoanodes showed promising potential in solar energy harvesting for efficient water splitting performance with high photocurrent density.
研究不足
The study focuses on the synthesis and application of green synthesized plasmonic nanostructures for PEC water splitting, but the scalability and long-term stability of these photoanodes in practical applications are not extensively discussed.
1：Experimental Design and Method Selection:
Synthesis of Au and Ag NPs via chemical reduction with green synthesized carbon nanolights (CNL) as a visible light photosensitizer for TiO2 nanofibers (TNFs).
2：Sample Selection and Data Sources:
TNFs were synthesized using a precursor solution consisting of ethanol, acetic acid, and titanium tetraisopropoxide. Plasmonic nanostructures (Au, Ag) were synthesized by a one-step process where CNLs act as a reducing agent.
