“…CoTe 2 exhibited superior activity compared to CoTe, which the authors attributed to be due to different binding and interaction strengths of the intermediates on CoTe and CoTe 2 . Unlike most studies where the formation of surface oxyhydroxide species are implicated in the OER of MX compounds and alloys, it was claimed in this study that Ni 3 Te 2 does not undergo any bulk or surface compositional changes, including corrosion or degradation . A film of Ni 3 Te 2 electrodeposited on a glassy carbon electrode afforded a current density of 10 mA cm −2 at only 180 mV, outperforming Ni chalcogenides with a similar stoichiometry, Ni 3 S 2 and Ni 3 Se 2 .…”

“…A NiTe catalyst on Ni foam attained a current density of 10 mA cm −2 at 262 mV overpotential, which is remarkable for a noble metal‐free OER catalyst, and makes it worthwhile to investigate the OER activity of metal tellurides in detail. There are increasingly more reports on the application of cobalt and nickel tellurides as electrocatalysts for the OER . The intensity of the Ni 2+ →Ni 3+ oxidation peak for the Ni 3 Te 2 film formed on gassy carbon by electrodeposition (figure a) is incredibly high and hints to a very high density of Ni active sites and hence high ECSA.…”

Compounds and alloys of cobalt and nickel with some nonmetals (N, P, S, Se) and metalloids (C, B, C, As and Te) have emerged as very promising noble metal-free pre-catalysts for the oxygen evolution reaction (OER) in alkaline electrolytes. However, the exact role played by the non-metals and metalloids in promoting the OER is not well understood. A holistic understanding of the origin of the OER activity enhancement in these compounds is vital for their exploitation as models to inspire knowledge-guided design of improved OER catalysts. In this review, we elucidate the factors that govern the activity and stability of OER catalysts derived from MX compounds (M = Co or Ni, and X = nonmetal or metalloid), including the impact of surface electronic structure, M : X stoichiometry, material composition, structure and crystallinity, as well as the role of oxoanions on the properties of the electrochemical double layer and interaction energies of the reaction intermediates. Finally, we outline a few perspectives and research directions towards a deeper understanding of the role of the nonmetal and metalloid elements and design of improved OER catalysts.[a] Dr.

“…However, the performances are reasonably poor as compared with other transition metal dichalcogenide systems, which may be ascribed to the more electronegativity of sulfur (∼2.58) in addition to their poor electronic conductivity . Herein, it is believed that the declination of electronegativity from oxygen to sulfur and to tellurium enhances the metallic features in chalcogenide series, which results in higher electrocatalytic performances of TMDs …”

Developing simple and cost‐effective bifunctional electrocatalysts for both hydrogen evolution reaction (HER) and oxygen evolution reaction (OER) is an effective strategy to curb the current energy demands. Herein, we report the hydrothermal synthesis of copper sulfide‐nickel sulfide (Cu2S‐Ni3S2) arrays supported by three‐dimensional conducting nickel foam as a substrate (Cu2S‐Ni3S2/NF). Cu2S‐Ni3S2/NF demonstrates prominent electrocatalytic activity and persistent stability (>25 h) in alkaline solution (1 M KOH), requiring the overpotential of −149 mV and 329 mV to drive the catalytic current density of 10 mA cm−2 for the HER and OER, respectively. Furthermore, overall‐water splitting in symmetrical configurations required the cell‐voltage of 1.77 V to deliver 10 mA cm−2, complimented with an ultra‐long term stability for 100 h. Therefore Cu2S‐Ni3S2/NF could be a promising and effective electrocatalyst for water‐splitting reactions.

“…In literature, oxides and alloys of precious metals, graphitic carbon nitrides, metal organic frameworks (MOFs) derived materials, metal contained covalent organic frameworks (COFs) etc., have shown appreciable catalytic activity towards ORR and OER . However, recent upsurge in developing a single electrode material for catalyzing both, ORR and OER stems due to their huge demand in energy applications …”

Bifunctional electrocatalysts that can catalyze both oxygen reduction and evolution reactions have high significance in the development of energy storage materials such as fuel cells and metal‐air batteries. Here, we have designed and synthesized a redox active porous organic polymer (TAPA‐PG) by the Schiff base condensation reaction between 4,4′,4′′‐triaminotriphenylamine (TAPA, donor) and 1,3,5‐triformylphloroglucinol (PG, acceptor). The TAPA‐PG possesses permanent microporosity and shows spherical nano‐morphologies with diameter of 400–500 nm. TAPA‐PG shows electrocatalytic activity towards oxygen reduction reaction (ORR) with an overpotential of 190 mV. Interestingly, TAPA‐PG is found to be efficient for in situ reduction of the Co(II) to Co(0) under ambient conditions, and results in a cobalt nanoparticles‐stabilized polymer matrix (Co@TAPA‐PG). Co@TAPA‐PG displays bifunctional electrocatalytic activity for ORR as well as oxygen evolution reaction (OER). Co@TAPA‐PG shows improved ORR catalysis as the overpotential dropped down significantly to 120 mV. The OER catalytic performance results in the maximum current density of 15.8 mA/cm2.The overpotential for OER is found to be 560 mV at the current density of 10 mA/cm2.
