A facile high-temperature molten salt bath method was developed to effectively dope sulfur into carbon. Molten potassium sulfide acts as a high-concentration sulfur source and provides an immersion bath, thus favoring sulfur doping. Resultant sulfur-

The photo-electrochemical behaviour of glassy carbon was investigated in the range of low anodic potentials, both in a supporting electrolyte alone and in the presence of electron donors (Fe2+,Ru(NH3)62+). The amount of the observed photo-current and
