Abstract
The growing global need for clean water and efficient energy storage has intensified interest in multifunctional material design. In the present work, TiB2-modified MIL-100(Fe) composites with varying TiB2 loadings were successfully synthesized via a hydrothermal route and evaluated as dual-functional materials for phenol oxidation and lithium-ion battery (LIB) anodes. Comprehensive structural and surface analyses (FT-IR, p -XRD, XPS, TGA, SEM, TEM, and BET) verified the uniform incorporation of conductive TiB2 into the porous MIL-100(Fe) architecture without evident phase separation. The catalytic performance of the composites was investigated through hydrogen peroxide-assisted phenol oxidation, and the reaction products were identified by GC–MS. Among the synthesized materials, the 10 wt% TiB2@MIL-100(Fe) composite exhibited the highest catalytic activity, achieving a maximum phenol conversion of 93.8% under optimized conditions while maintaining good reusability over repeated cycles. The enhanced catalytic behavior is attributed to the cooperative interaction between the redox-active MIL-100(Fe) and the conductive TiB2 phase. Electrochemical measurements further revealed that TiB2 incorporation significantly improves the lithium storage performance of MIL-100(Fe). The 10 wt% TiB2@MIL-100(Fe) electrode delivered a high initial discharge capacity and maintained a reversible capacity of 330 mAh/g after three cycles. Cyclic voltammetry and electrochemical impedance spectroscopy confirmed improved redox kinetics, reduced charge-transfer resistance, and enhanced Li+ diffusion in the composite electrode. Overall, the TiB2@MIL-100(Fe) composites demonstrate promising potential as multifunctional materials for environmental remediation and advanced energy storage applications.
