Tailoring nanocatalysts and reaction interfaces for water- and CO2-electrolysis
Renewable energy sources offer a promising solution for mitigating sustainability and CO2 emissions-related issues due to their vast energy generation capacity. They enable hydrogen production via water electrolysis, as well as carbon capture and utilizati ...
EPFL2024Graphene nanoplatelets promoted CoO-based catalyst for low temperature CO2 methanation reaction
Thi Ha My Pham, Youngdon Ko, Liping Zhong
Methanation of CO2 is an important reaction for reducing CO2 emissions in a power-to-gas system. Compared to cobalt supported on gamma-Al2O3, cobalt supported on graphene nanoplatelets (GNPs) showed significantly better performance for CO2 methanation. Cob ...
FRONTIERS MEDIA SA2023Understanding the role of surface oxygen-containing functional groups on carbon-supported cobalt catalysts for the oxygen evolution reaction
Andreas Züttel, Thi Ha My Pham, Kangning Zhao, Youngdon Ko, Liping Zhong, Manhui Wei
Supported Co-based catalysts exhibit promising catalytic activities in the oxygen evolution reaction (OER) during alkaline water electrolysis. Surface functionalization of the support modulates the dispersion of the catalysts and their interaction with the ...
ROYAL SOC CHEMISTRY2023A fluoropolymer bifunctional solid membrane interface for improving the discharge duration in aqueous Al-air batteries
Thi Ha My Pham, Liping Zhong, Manhui Wei, Meixia Zhang
Herein, a fluoropolymer bifunctional solid membrane interface (SMI) for an aqueous Al-air battery is proposed, which inhibits anodic self-corrosion, while concurrently reducing the accumulation of undesirable by-products. A battery using the SMI exhibits a ...
ROYAL SOC CHEMISTRY2023Zinc carboxylate optimization strategy for extending Al-air battery system's lifetime
Andreas Züttel, Thi Ha My Pham, Liping Zhong, Manhui Wei
Although Al-air batteries are expected to be the candidates for energy conversion systems in renewable energy market due to the higher energy density, richer reserves, and lighter mass of Al metal, the anode self-discharge is seen as a notorious issue that ...
ELSEVIER SCI LTD2023Tandem effect of Ag@C@Cu catalysts enhances ethanol selectivity for electrochemical CO2 reduction in flow reactors
Andreas Züttel, Thi Ha My Pham, Cedric David Koolen, Wen Luo, Jie Zhang, Mo Li, Youngdon Ko, Liping Zhong
CO-selective metals (e.g., Ag) on Cu catalysts improve the selec-tivity of multi-carbon (C2+) products in electrochemical CO2 reduc-tion. However, the origin of the improvement remains unclear due to the convolution of tandem and interface effects. Here, A ...
ELSEVIER2022Support-Dependent Cu-In Bimetallic Catalysts for Tailoring the Activity of Reverse Water Gas Shift Reaction
Thi Ha My Pham, Wen Luo, Kun Zhao, Mo Li, Youngdon Ko, Liping Zhong
Cu-based bimetallic catalysts have attracted great attention for the reverse water gas shift (RWGS) reaction due to their high activity and selectivity. This work reports the application of Cu-In bimetallic catalysts for the RWGS reaction and demonstrates ...
AMER CHEMICAL SOC2022Revealing the Surface Chemistry for CO2 Hydrogenation on Cu/CeO2–x Using Near-Ambient-Pressure X-ray Photoelectron Spectroscopy
Andreas Züttel, Emad Oveisi, Thi Ha My Pham, Wen Luo, Mo Li, Young Jun Ko
Catalytic reduction of CO2 to valuable products is an attractive route for CO2 recycling. CeO2-supported Cu catalysts have shown high activity and selectivity for the hydrogenation of CO2 to CO. To uncover the origin of their high performance, we prepared ...
ACS2021Oxygen Evolution Reaction in Ba0.5Sr0.5Co0.8Fe0.2O3-delta Aided by Intrinsic Co/Fe Spinel-Like Surface
Vasiliki Tileli, Thi Ha My Pham, Tzu-Hsien Shen, Jan Vávra
Among the perovskites used to catalyze the oxygen evolution reaction (OER), Ba0.5Sr0.5Co0.8Fe0.2O3-delta (BSCF) exhibits excellent activity which is thought to be related to dynamic reconstruction at the flexible perovskite surface due to accommodation of ...
