Objective comparisons of electrocatalyst activity and stability using standard methods under identical conditions are necessary to evaluate the viability existing electrocatalysts for integration into solar-fuel devices as well help inform development new catalytic systems. Herein, we use a protocol primary screen evaluating activity, short-term (2 h) stability, electrochemically active surface area (ECSA) 18 hydrogen evolution reaction (HER) 26 oxygen (OER) relevant an integrated solar water-splitting device in aqueous acidic or alkaline solution. Our figure merit is overpotential achieve magnitude current density 10 mA cm(-2) per geometric area, approximate expected 10% efficient solar-to-fuels conversion 1 sun illumination. The specific ECSA each material also reported. Among HER catalysts, several could operate at with overpotentials <0.1 V and/or solutions. OER catalysts solution, no non-noble metal based materials showed promising whereas solution many performed similar achieving densities ~0.33-0.5 V. Most comparable better when compared Ir Ru solutions, while most much lower than Pt both For select additional secondary screening measurements were conducted including Faradaic efficiency extended measurements.

Recent Trends and Perspectives in Electrochemical Water Splitting with an Emphasis on Sulfide, Selenide, and Phosphide Catalysts of Fe, Co, and Ni: A Review

ACS Catalysis, Journal Year: 2016, Volume and Issue: 6(12), P. 8069 - 8097

Increasing demand for finding eco-friendly and everlasting energy sources is now totally depending on fuel cell technology. Though it an way of producing the urgent requirements, needs to be improved make cheaper more eco-friendly. Although there are several types cells, hydrogen (H2) oxygen (O2) one with zero carbon emission water as only byproduct. However, supplying fuels in purest form (at least H2) essential ensure higher life cycles less decay efficiency. The current large-scale H2 production largely dependent steam reforming fossil fuels, which generates CO2 along source going depleted. As alternate, electrolysis has been given greater attention than reforming. reasons follows: very high purity produced, abundant source, no need high-temperature, high-pressure reactors, so on. In earlier days, noble metals such Pt (cathode) Ir Ru (anode) were used this purpose. problems employing these metals, they expensive. review, we elaborate how group VIII 3d metal sulfide, selenide, phosphide nanomaterials have arisen electrode materials (catalysts) beyond oxides hydroxides same.

Homogeneously dispersed multimetal oxygen-evolving catalysts

Science, Journal Year: 2016, Volume and Issue: 352(6283), P. 333 - 337

Published: March 25, 2016

Earth-abundant first-row (3d) transition metal-based catalysts have been developed for the oxygen-evolution reaction (OER); however, they operate at overpotentials substantially above thermodynamic requirements. Density functional theory suggested that non-3d high-valency metals such as tungsten can modulate 3d metal oxides, providing near-optimal adsorption energies OER intermediates. We a room-temperature synthesis to produce gelled oxyhydroxides materials with an atomically homogeneous distribution. These FeCoW exhibit lowest overpotential (191 millivolts) reported 10 milliamperes per square centimeter in alkaline electrolyte. The catalyst shows no evidence of degradation after more than 500 hours operation. X-ray absorption and computational studies reveal synergistic interplay between tungsten, iron, cobalt producing favorable local coordination environment electronic structure enhance energetics OER.

Abstract Large-scale industrial application of electrolytic splitting water has called for the development oxygen evolution electrodes that are inexpensive, robust and can deliver large current density (>500 mA cm −2 ) at low applied potentials. Here we show an efficient electrode be developed by electrodepositing amorphous mesoporous nickel–iron composite nanosheets directly onto macroporous nickel foam substrates. The as-prepared exhibits high catalytic activity towards oxidation in alkaline solutions, which only requires overpotential 200 mV to initiate reaction, is capable delivering densities 500 1,000 overpotentials 240 270 mV, respectively. also shows prolonged stability against bulk electrolysis current. Collectively, three-dimensional structured most electrolytes reported best our knowledge, potentially scale electrolysis.
