EC-MS Publications

Nature Communications study: MoS₂ HER stability is allotrope-dependent — lamellar MoS₂ degrades at open circuit, while amorphous MoS₃ₓ loses sulfur during HER, monitored via simultaneous ICP-MS and EC-MS.

ACS Energy Letters study: real-time EC-MS detection reveals acetaldehyde's role in electrochemical CO reduction on Cu single crystals, and its fast non-Faradaic oxidation to acetate in alkaline media.

A TAS electrolyte additive suppresses hydrogen evolution during Zn electrodeposition by an order of magnitude, improving zinc anode stability and extending cycle life ~25-fold.

JACS study: size-selected gold nanoparticles peak in CO2-to-CO selectivity at ~3 nm, with multiply twinned particles and 8-fold coordinated surface sites identified as the key design target.

Angewandte Chemie study: in-situ EC-MS shows zinc metal batteries lose just 0.3% of charge to hydrogen evolution during electrodeposition — yet this correlates with porosity, trapped H₂, and long-term corrosion risk.

Angewandte Chemie study: an on-chip EC-MS method reveals how lithium ion batteries degrade — detecting oxygen evolution from NMC cathodes, SEI formation, and the first direct evidence of CO₂ reduction to ethylene.

Carbon (2023) study: oxygen functionalities and sp² carbon content are identified as the key durability levers for carbon supports in Pt alloy fuel cell catalysts, using combined EC-MS and XPS degradation testing.

ACS Catalysis study: DFT calculations reveal why lithium is uniquely suited for electrochemical nitrogen fixation, proposing descriptors to identify viable beyond-Li systems.

Catalysis Science & Technology study: EC-MS shows methane adsorption on Pt peaks at 0.3 V vs. RHE, with *CO as the dominant surface intermediate — explaining Pt's poor performance for methane valorisation.

ACS Catalysis study: dissolved ion concentration inflates measured RuO₂ stability for the acidic oxygen evolution reaction — revealing RuO₂ is far less stable, though more active, than IrO₂.

Tuning H₂O thermodynamic activity in water-in-salt electrolytes steers Cu-catalysed CO2 electroreduction to multicarbon products, boosting CO coverage and shifting C2+/C1 ratios up to 20-fold for higher C–C coupling.

A hematite/NiOOH photoelectrode paired with an AgCl cathode selectively oxidizes urea under LED light alone, producing N₂ with no ammonia or nitrate — a step toward a practical wearable artificial kidney.

This work achieves electrocatalytic scission of the unactivated C(sp3)–C(sp3) bond in ethane at room temperature, using real-time manipulation of surface bound intermediates on nanoporous Pt for unprecedented selectivity control.

On boron-doped diamond electrodes, decarboxylation of acetic acid reaches 90% faradaic efficiency without competing OER; Pt-functionalised BDD shifts selectivity to ethane, with thin Pt layers giving >70% FE — a practical route for pyrolysis-oil acidity reduction.

A comprehensive critical review of impurities on water electrolysis across PEM, alkaline, and anion exchange membrane systems — covering impurity sources, degradation mechanisms, characterisation techniques, and mitigation strategies.
