“…Ruthenium dioxide (RuO 2 ), iridium dioxide (IrO 2 ), and mixed oxides containing these two noble metals have been proved to have high electrocatalytic activity for the OER. [171][172][173][174][175][176][177] Ir x Ru y Ta z O 2 as an anode electrocatalyst achieved an overall cell voltage of 1.57 V at 1 A cm −2 at 80 °C, with an energy consumption of 3.75 kWh N m −3 H 2 and efficiency of 94%, for a total noble metal loading of less than 2.04 mg cm −2 . 47 However, there are some non-noble, less expensive metals that also present electrocatalytic activity and are being introduced for use in oxygen [178][179][180][181][182][183][184][185] and hydrogen 165,166,[186][187][188][189][190][191] evolution reactions.…”

Recebido em 13/12/12; aceito em 28/5/13; publicado na web em 17/7/13Water electrolysis is one of the simplest methods used for hydrogen production. It has the advantage of being able to produce hydrogen using only renewable energy. To expand the use of water electrolysis, it is mandatory to reduce energy consumption, cost, and maintenance of current electrolyzers, and, on the other hand, to increase their efficiency, durability, and safety. In this study, modern technologies for hydrogen production by water electrolysis have been investigated. In this article, the electrochemical fundamentals of alkaline water electrolysis are explained and the main process constraints (e.g., electrical, reaction, and transport) are analyzed. The historical background of water electrolysis is described, different technologies are compared, and main research needs for the development of water electrolysis technologies are discussed.

“…2 (by FESEM), which was introduced in our former articles in details [10]. The cluster crystals which were formed at the process of sintering are rutile phase IrO 2 grains [11]. Plenty of IrO 2 grains are distinct on the surface of the anode with oxalic acid etching substrate, and the size is larger than the others.…”

“…Oxygen evolution occurs on noble metal electrodes (e.g., Pt, Au, Ir, Rh, Ru, Ag), but metal oxides (eg., RuO 2 , IrO 2 ) are generally more active electrocatalysts for oxygen evolution than metal electrodes [8]. Noble metal oxides (Pt, Ir, Ru, Ta) and/or their combinations as electrocatalysts are well established in many industrial electrochemical processes in the form of dimensionally stable anodes [7,9]. Within the last 15 years the higher reported performance for Nafion Ò PEM electrolyzers (T 90 C), was with the use of Ir, PteIr, IreRu and IreTa oxides, while IreRu has been proven to be the most active O 2 evolution electrocatalyst.…”
