![]() It is reported that introducing other noble metals can tremendously increase the number of active sites and produce complementary effects, so the idea of utilizing Ru as dopant come into being. As mentioned, the cations in NCO occupy different sites and have complex valence state, the substitution of these cations may cause unexpected effects. As far as we know, NCO or even spinel family can rarely be used as bifunctional for both HER and OER, so it is a big challenge to simultaneously improve the HER and OER performance of NCO. The efficiency of an alkaline electrolysis stack is only 63–71% LHV owing to the high overpotential in two half reactions, and industrial alkaline electrolyzers usually suffer from low operational current densities (1000 mA cm −2). However, overall water splitting composed of two half reactions, namely hydrogen evolution reaction (HER) and oxygen evolution reaction (OER), is thermodynamically unfavorable process that restricted by the high intrinsic activation barriers,. ![]() Among the current industrial electrolysis systems, alkaline electrolysis is most advanced due to the safety and long lifetimes. Energy Information Administration) have stimulated scientific researchers to explore electrocatalysts for the production of hydrogen from water electrolysis. Meanwhile, the ever-decreasing electricity prices (average 6.41 cents/kwh for industrial electricity in the United States on Apr 2020, U.S. The conversion of chemical energy stored by hydrogen fuel into electricity is an effective approach to solve this critical issue. Payments will be made via a virtual invoice emailed to the winner.Developing renewable and eco-friendly energy sources like tidal and solar energy is essential to our society due to the sharp deterioration of the environment caused by the excessive use of fossil fuels, , while the intermittent nature of these energy sources impedes their continuous electric energy supply.
