研究目的
Investigating the continuous synthesis of monodisperse yolk-shell titania microspheres using a microfluidic strategy.
研究成果
The developed microfluidic strategy enables the continuous synthesis of highly monodisperse and porous yolk-shell titania microspheres with tunable size, surface morphology, and crystalline phase. The method demonstrates high throughput and versatility, offering a significant advancement over traditional batch synthesis methods.
研究不足
The study focuses on the synthesis process and characterization of titania microparticles, with potential limitations in scalability and application-specific performance not fully explored.
1：Experimental Design and Method Selection:
A microfluidic reactor was designed for continuous synthesis, utilizing a polar aprotic solvent as the continuous phase to decouple microdroplet formation and hydrolysis reaction steps.
2：Sample Selection and Data Sources:
Titanium tetrabutoxide (TBT) was used as the precursor, with ethoxylated trimethylolpropane triacrylate (ETPTA) and toluene as solvents.
3：List of Experimental Equipment and Materials:
Microreactor components included glass capillaries, syringe pumps, and a high-speed camera for monitoring.
4：Experimental Procedures and Operational Workflow:
Microdroplets were formed in the microreactor, collected in a water bath for hydrolysis, UV cured, washed, dried, and calcined.
5：Data Analysis Methods:
SEM, BET, and XRD were used for characterization of the microparticles.
