Overview | Product Information | MSDS | Literature & Reviews | Related Products | Technical Support
TEPA‑functionalized reduced graphene oxide (TEPA-rGO) is a graphene-based material in which tetraethylene pentamine (TEPA) molecules are covalently grafted onto the surface of reduced graphene oxide. Functionalization with TEPA introduces amine groups, improves dispersibility, and enhances surface reactivity.
TEPA-rGO demonstrates outstanding compatibility with MXene materials, forming hybrid structures that deliver optimized Faradaic and capacitive responses. These composites have been successfully applied in sensitive electrochemical detection systems for interleukin-6, a key pro-inflammatory cytokine and important biomarker in clinical diagnostics. TEPA-rGO also plays a crucial role in advanced bioelectrochemical systems. When used as an electrode modification material for microbial electrosynthesis, it promotes efficient microbial attachment and electron transfer. The resulting three-dimensional conductive network enhances the reduction of CO2. These systems have demonstrated acetate production rates of 321 ± 53 mM/m2day, highlighting the strong potential of TEPA-rGO for sustainable carbon conversion and bioelectrochemical technologies.
