Chronopotentiometric approach of CO2 reduction in molten carbonates
(2017)Carbon capture and valorization is a new route increasingly discussed to reduce greenhouse gas emissions. One of the paths foreseen for CO2 valorization is its transformation into fuels by electrochemical reduction of ... -
Effect of precipitate coherency on the corrosion-induced hydrogen trapping in 2024 aluminum alloy
(2021)Hydrogen trapping is one of the factors leading to hydrogen embrittlement in heat-treatable high-strength aluminum alloys. The effect of coherency of precipitates on the corrosion-induced hydrogen trapping in aluminum alloy ... -
Highly efficient electrocatalysts for oxygen reduction reaction: Nitrogen-doped PtNiMo ternary alloys
(2019)The relatively low efficiency of the reaction of oxygen reduction (ORR) remains among the main obstacles for hydrogen fed proton exchange membrane fuel cells (H-PEMFCs) commercialization. In the present work, PtNiMo ternary ... -
Mesoporous IrNiTa metal glass ribbon as a superior self-standing bifunctional catalyst for water electrolysis
(2022)Metallic glasses (MGs) only show single activity for water electrolysis and rarely show superior bifunctional activity for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER). In this work, IrNiTa ... -
Molybdenum-modified and vertex-reinforced quaternary hexapod nano-skeletons as efficient electrocatalysts for methanol oxidation and oxygen reduction reaction
(2019)Noble metal binary and ternary catalysts have become a new class of fuel cell electrocatalysts due to their high catalytic activity. However, improvement is still necessary to reduce the consumption of Pt and obtain the ...
