^*Standard experimental electrolysis reaction conditions: buffer was 50 mM Tris⋅HCl, 0.18 M KCl. 16 mM MgCl₂; 800 μM initial camphor concentration; E_we = −0.7 V on the tin oxide working electrode; temperature was 21–22°C. 

^†Standard condition except initial camphor concentration was 2 mM. 

^‡Standard condition except initial camphor concentration was 2 mM and temperature was 37°C.
