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 water activity in concentrated salt electrolytes from 0.97 to 0.47 controls C–C coupling vs. C1 product formation on Cu, achieving ~73% faradaic efficiency toward C2+ at −110 mA cm⁻² at modest overpotentials. Lower H₂O activity raises CO surface coverage and shifts C2+/C1 ratios up to 20-fold — establishing thermodynamic water activity as a practical selectivity lever for CO₂ reduction.

A hematite/NiOOH photoelectrode paired with an AgCl cathode selectively oxidises urea over chloride under LED illumination alone — no external bias required. MS confirms N₂ as the primary nitrogen product with no ammonia or nitrate, and extrapolation suggests 0.5 m² of electrode area could clear a day's urea load within 24 hours, enabling a viable wearable artificial kidney concept.

NiFeOxHy water oxidation nanoparticle size and lattice oxygen studied by operando EC-MS shows OER in 1M KOH is surface-limited at a record 6.2 s-1.

BDD electrodes decarboxylate acetic acid at 90% faradaic efficiency without competing OER, forming methanol and methyl acetate via hydroxyl radical reactions. Pt-modified BDD shifts selectivity toward ethane (Kolbe product), with thin Pt layers achieving >70% FE — offering a practical route for electrochemical acidity reduction in pyrolysis oil upgrading.
