Oxygen‐Bridged Ga‐O‐PtPd Triple Sites Boost Methanol‐Assisted Rechargeable Zn‐Air Batteries Through Suppressing CO_ads Generation

Advanced Energy Materials, Journal Year: 2025, Volume and Issue: unknown

Published: March 4, 2025

Abstract Constructing high‐efficiency platinum (Pt)‐based catalysts for methanol oxidation reaction (MOR) by suppressing the intermediate CO ads generation is strongly desired and remains a grand challenge. Herein, concept of holding O‐bridged triple sites documented to strengthen “non‐CO” pathway selectivity forming HCOO − species during MOR. The obtained Ga‐O‐PtPd via grafting single‐atomic Ga on PtPd nanosheets achieves high current density 3.05 mAcm −2 MOR, which 5.65 times higher than commercial Pt/C (0.54 ), as well remarkably stability poison resistance. diffuse reflectance infrared Fourier transform spectroscopy (CO‐DRIFTS) results reveal that present weak binding ability, reducing intermediate. In addition, Ga‐O‐PtPd‐based Zn‐methanol‐air batteries an excellent activity compared with catalysts.

Pt Nanoparticles on Multi-Walled Carbon Nanotubes with High CO Tolerance for Methanol Electrooxidation

Molecules, Journal Year: 2024, Volume and Issue: 29(21), P. 5015 - 5015

Published: Oct. 23, 2024

Anode catalysts are important for direct methanol fuel cells (DMFCs) of energy conversion. Herein, we report a novel strategy by ethylene glycol-based deep eutectic solvents (EG-DESs) the fabrication multi-walled carbon nanotubes (MWCNTs)-supported Pt nanoparticles catalyst (referred to as Pt/CNTs-EG-DES). The Pt/CNTs-EG-DES provides an increased electrochemically active surface area (ECSA) and shows remarkably improved electrocatalytic performance towards oxidation reaction compared Pt/CNTs-W (fabricated in water) commercial Pt/C catalysts. is attributed generation more Pt-O bonds which change electronic states atoms special node structure that obtains sites high CO resistance. This study suggests effective synthesis Pt-based electrocatalysts with DMFC applications.
