CdSe Nanoparticles Synergized with 2D Ti₃C₂T_x MXene as the Dual-Function Composite for Enhanced K⁺ Ion Storage and Water Splitting

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: April 11, 2025

Developing high-performance materials for energy storage and water splitting remains a significant challenge in research. Metal selenides, such as CdSe, exhibit excellent electrical conductivity electrochemical activity, but they tend to form aggregates. Two-dimensional (2D) Ti3C2Tx MXene has good stability is limited by its low capacitance electrocatalytic performance. To address these issues, CdSe@Ti3C2Tx composites were synthesized two-step large-scale hydrothermal method, where CdSe nanoparticles uniformly grown on nanosheets. The significantly enhance the specific capacity, ion mobility, cycling stability, catalysis activity due synergistic effect between nanoparticles. In three-electrode system, achieve of 1847 F g-1 at 0.125 mA cm-2 retain 89.2% their after 10 000 cycles, demonstrating superior properties compared those CdSe- or Ti3C2Tx-based electrodes. asymmetric supercapacitor (ASC) with positive electrode activated carbon (AC) negative 219.1 g-1, capacity retention 88.1% 5000 an density 45.8 W kg-1. This research also analyzes reasons performance enhancement from perspective states theory. Furthermore, composite shows catalytic potential splitting, overpotentials 201 mV hydrogen evolution reaction (HER) 276 oxygen (OER). These results suggest that 2D MXene-based promising candidate splitting.
