Modulation of Hydrogen Evolution Reaction Performance of MXenes by Doped Transition Metals: Comprehensive Exploration of High-Throughput Computing and Machine Learning

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

Published: April 10, 2025

Due to the unique properties of MXenes, doping transition metals can modulate their catalytic and make them potential materials for hydrogen evolution reaction (HER). Nevertheless, extensive combinatorial space poses a challenge rapid screening catalysts. To address this issue, we conducted high-throughput calculations on series metal atom-doped Ti3CNO2 Zr2HfCNO2. Furthermore, local structure corresponding electronic changes are analyzed, focusing influence HER properties. site identification features were introduced train multisite prediction model with final accuracy R2 = 0.97 predicted trend adsorption Gibbs free energy (ΔGH*) across range MXenes structures, which doped TM atoms. The results show that Nb, Sc, Rh, W, Ti, V resulted in |ΔGH*| < 0.2 eV more than 38 M'2M″CNO2, respectively, they effective dopant atoms enhancing ability M'2M″CNO2.

Enhanced voltage and capacitance in flexible supercapacitors using electrospun nanofiber electrolytes and CuNi2O3@N-Doped omnichannel carbon electrodes

Nano Convergence, Journal Year: 2025, Volume and Issue: 12(1)

Published: April 29, 2025

Abstract Developing functional solid polymer electrolytes (SPEs) is crucial for flexible, lightweight, and portable supercapacitors. This work presents an electrospinning approach to fabricate SPEs using poly(vinyl alcohol)-sodium chloride (PVA-NaCl) nanofibers (PNNF). CuNi 2 O 3 nanoparticles deposited on nitrogen-doped omnichannel carbon (CuNi @N-OCCFs), coated onto a cloth (CC), serve as the positive electrode, enhancing faradaic capacitance. Meanwhile, rationally designed N-OCCFs, also CC, function negative providing high-surface-area, facilitating rapid electron transport. Comprehensive characterization revealed insights into morphology chemical composition of both electrodes PNNF electrolyte. An all-solid-state asymmetric flexible supercapacitor (AFSC) device, @N-OCCFs-1.5//N-OCCFs-1.5, was assembled electrolyte separator evaluated against devices employing gel aqueous electrolytes.
