(a) Potential programme for the repeated generation and desorption of methane from butane adsorbed at 0.3 V for 15 min. Inset: Methane generation is hypothesized to occur through two steps. The fragmentation potential (E₁) was varied between 0.4 and 0.7  V. E₂, desorption potential; t₁, time of fragmentation step; t₂, time of desorption step. (Reproduced from Ref. [85].

Conditions: divided cell; Pt/Pt (1.0 cm² each); 10 mA; 1/2 (0.5 mmol each), CH₃CN (10 mL), TBABF₄ (0.3 M), rt. (Reproduced from Ref. [87]. Copyright©2020, Wiley-VCH GmbH).
