研究目的
Investigating the controllable synthesis of gold nanoparticles (AuNPs) with cucurbit[n]urils (CB[n]s) and their catalytic performance in the reduction of 4-nitrophenol.
研究成果
The study demonstrated that the size of AuNPs can be controlled by CB[n]s with different ring sizes, and the catalytic activity is dependent on the particle size and CB[n] packing density. Smaller particles with less CB[5] exhibit higher activity due to reduced blocking of reactive surface sites. This work opens new avenues for applications of CB[n]-capped AuNPs in catalysis, sensing, and drug delivery.
研究不足
The study is limited to the use of CB[n]s (n = 5–8) as capping agents and the catalytic reduction of 4-nitrophenol. The effect of other macrocycles or different catalytic reactions was not explored.
