Square-wave voltammetry of 5-fluorouracil [PDF]

Journal of Electroanalytical Chemistry, 2000
The redox reaction of 5-fluorouracil (FU) at hanging mercury drop electrode (HMDE) is studied of square-wave volrammetry (SWV). It is demostrated that the redox raction proceeds according to the sheme L2-(aq) --- L2-(ads) + Hg(l) --Hg(s) + 2e-, which involves both chemosorption of FU on the electrode surface and creation of a sparingly soluble compound

Magnetic‐Field Control of Surface States in CoFe2O4 Thin Films for Nitrate Electroreduction to Ammonia

Advanced Functional Materials, EarlyView.
Magnetic‐field‐assisted CVD of heterometallic single‐source precursors modulates thin‐film surface electronic structure and interfacial charge transfer. Field‐grown (Cobalt ferrite‐1T)CF‐1T films exhibit stabilized electronic states, lower kinetic barriers, and markedly enhanced nitrate‐to‐ammonia electrocatalysis versus (Cobalt ferrite‐0T) CF‐0T ...
