研究目的
Investigating the influence of semiconductor morphology on the photocatalytic activity of plasmonic photocatalysts, specifically comparing titanate nanowires and octahedral anatase nanoparticles.
研究成果
The study concludes that the morphology of the semiconductor and the type of noble metal significantly influence the photocatalytic activity. OAP samples showed higher activity than TNW samples, attributed to their anatase presence, higher crystallinity, and electron mobility. Platinum-modified samples were most active for hydrogen liberation, while gold-modified TNW and platinum-modified OAP were most active for acetic acid decomposition. The efficiency of plasmonic photocatalysis under visible light depends on the metal's oxidation state, photoabsorption properties, and the semiconductor's morphology and crystallinity.
研究不足
The study focuses on specific morphologies (OAP and TNW) and noble metals (Au, Ag, Pt), potentially limiting the generalizability to other morphologies or metals. The photocatalytic activities were tested under controlled conditions, which may not fully replicate real-world applications.
