15 sty 2018 · Compared with the polished Cu foil, our 100-cycled Cu nanocube catalyst with exposed (100) facets presents a sixfold improvement in C 2+ to C 1 product ratio, with a highest C 2+ Faradaic ...
10 sie 2021 · The obtained Co(OH)2 @NC exhibits remarkable activity in terms of a lower overpotential of 330 mV@10 mA cm −2 for OER and a more positive half-wave potential (E 1/2 = 0.84 V) for ORR in alkaline medium, outperforming IrO 2 and Pt/C. Due to its superior bifunctional catalytic performance, Co(OH) 2 @NC catalyst is applied into a promising air ...
19 paź 2020 · Here we report a strategy to reprogram the Fe, Co and Ni oxidation cycles by incorporating high-valence transition-metal modulators X (X = W, Mo, Nb, Ta, Re and MoW).
17 mar 2022 · The trends in C 2 Oxy/HC selectivity revealed in this work, unveils the sensitivity of C 2 Oxy formation on the electrolyte pH and the binding affinities of a catalytic surface and thus...
29 paź 2024 · During the electrochemical CO 2 reduction reaction (eCO 2 RR) on copper catalysts, linear-bonded CO (*CO L) is commonly regarded as the key intermediate for the CO-CO coupling step, which leads to the formation of multicarbon products.In this work, we unveil the significant role of bridge-bonded *CO (*CO B) as an active species.By combining in situ Raman spectroscopy, gas and liquid ...
1 cze 2024 · AIMD simulations with explicit solvation reveals that the *OOH is unstable with the interaction of neighboring water molecular, and generated ·OH species in the aqueous media respond to the redox event (2·OH → H 2 O 2), suggesting a new reaction path for H 2 O 2 production.
15 maj 2017 · In this work, we developed a facile two-phase protocol to fabricate an α-Co(OH) 2 using sodium oleate as the phase-transfer surfactant. The crystallinity and structure of the α-Co(OH) 2 was regulated by heat treatments toward enhanced electrocatalytic OER activity.
