I am seeking suggestion on reference electrodes which I can use in highly acidic solvents like conc. H2SO4?

I am doing some electrochemistry in highly acidic solvents (Conc. H2SO4, Conc. HCl etc). But I m sure that Ag/AgCl reference electrode is not suitable for this. So, can anyone give some suggestion?

Is there an ideal incubation time of RGO-modified SPCE before subsequent use, i.e., electrochemical characterization or further modification?

I notice that upon washing and air-drying of my RGO/SPCE surface and characterizing again via DPV, the current response towards ferricyanide probe significantly decreases. My worry is that the...
