研究目的
Investigating the factors that influence the photocatalytic performance of inorganic lead halide perovskite quantum dots (iLHP-QDs) and improving their performance through surface modification.
研究成果
The CsPbI3 QDs showed the best photocatalytic performance due to its narrow bandgap and low exciton binding energy. Post-treatment with methyl acetate enhanced the photocatalytic performance by replacing oleic acid with shorter acetate acid and introducing traps on the QDs surface. These findings could aid in designing more efficient photocatalytic systems and further promote the application of iLHP-QDs.
研究不足
The study focuses on the influence of halide composition and surface modification on the photocatalytic performance of iLHP-QDs, but does not explore other potential factors or applications beyond photocatalytic polymerization of TerEDOT.
