摘要

An electrochemical study was conducted to evaluate the behaviour of modified electrodes of the DSAtype (dimensionally stable anodes) with the purpose of determining its viability to produce hydrogen(H2(g)) through the catalytic electrolysis of water. The DSA electrodes were manufactured with a sheetof A304 stainless steel or Ti as the substrate, applying a coating of RuO2 by the modified Pechinimethod. Also, different types of materials were tested as cathodes, including plates of titanium (Ti),silver (Ag), stainless steels A304 and A316, graphite rods (GR), glassy carbon (VC) and platinum (Pt).The results showed that the use of A304|RuO2 and Ti|RuO2 DSA electrodes allowed lower cathodicpotentials (≤ 1.0 V) for the start of the water reduction reaction to produce H2(g). The best arrangementand electrode material for the catalytic production of H2(g) was a DSA electrode of A304|RuO2 andA304 stainless steel plate as the cathode, which was even better than platinum, showing a high stabilityto modify their surface and structure. In conclusion, the use of a A304 stainless steel plate as asubstrate instead of titanium to prepare DSA electrodes of A304/RuO2 for the catalytic production ofH2(g) is viable and inexpensive.
