What are the Challenges Associated with Gold Nanorods in Catalysis?
Despite their advantages, gold nanorods face several challenges in catalysis:
1. Stability: Maintaining the stability of gold nanorods under reaction conditions can be difficult. They may aggregate or undergo morphological changes, which can reduce their catalytic efficiency. 2. Cost: Gold is an expensive material, which can limit the large-scale application of gold nanorod-based catalysts. 3. Toxicity: The use of surfactants like CTAB in the synthesis process raises concerns about the potential toxicity and environmental impact of these materials.
