研究目的
Investigating the influence of different catalysts on the phase and morphology evolution of boron nitride (BN) nanostructures synthesized via a hydrothermal method.
研究成果
The study demonstrated that the phase and morphology of BN nanostructures can be controlled by selecting appropriate catalysts in hydrothermal synthesis, offering a cost-effective method for large-scale fabrication of BN materials with potential applications in electronic packaging.
研究不足
The reaction mechanism is difficult to ascertain due to the dark room reaction under hydrothermal conditions. The purity of the products remains a challenge.
1：Experimental Design and Method Selection:
A hydrothermal method was used to synthesize BN nanostructures, with glycine as the nitrogen source and various catalysts (NaF, NH4F, NaCl) to investigate their effects on the phase and morphology of BN products.
2：Sample Selection and Data Sources:
The reactants included Boric acid (H3BO3), Glycine (Gly), and different catalysts (NaF, NH4F, NaCl). The products were characterized using FESEM, XRD, TEM, and XPS.
3：List of Experimental Equipment and Materials:
Stainless-steel autoclave, FESEM (Nova NanoSEM 450, FEI), XRD (Rigaku, D/max-2500Pc), TEM (Tecnai F20), XPS (ESCALAB MKII).
4：Experimental Procedures and Operational Workflow:
The mixture of reactants was sealed in an autoclave, heated to 300 °C for 24 h, then cooled, centrifuged, washed, and dried.
5：Data Analysis Methods:
XRD patterns were analyzed to distinguish phases, SEM and TEM for morphology, and XPS for chemical composition.
