Application

  • Biocompatible Polymer Composites: Research demonstrates the development of a reactive compatibilization method using 1,4-diazabicyclo[2.2.2]octane as a catalyst for the preparation of polylactic acid/poly(butylene adipate-co-terephthalate)/thermoplastic starch ternary bio-composites. This approach significantly improves the mechanical and biodegradable properties of the composites, suitable for environmentally friendly applications in the packaging and automotive industries (Fang et al., 2024).
  • Cobalt Single-Atom Catalysts: Research on the development of cobalt single-atom catalysts encapsulated in a metal-organic framework using 1,4-diazabicyclo[2.2.2]octane. This catalyst shows exceptional efficiency in the oxygen reduction reaction, important for energy conversion technologies such as fuel cells and metal-air batteries (Gao et al., 2024).
  • Advanced Analytical Techniques: Study on the use of 1,4-diazabicyclo[2.2.2]octane in advanced derivatization techniques for the analysis of Novichok agents in biofluids using LC-MS. This research contributes to the field of forensic science and chemical warfare agent detection, providing robust methods for emergency responses and public safety (Yamaguchi et al., 2023).
