Green synthesis of fusiform-shaped Fe-PANI as a phenomenal dual electrocatalyst for overall water splitting and assessment of its sustainability standards

Abstract

Development of eco-friendly dual electrocatalysts for oxygen evolution reaction (OER) and hydrogen evolution reaction (HER) gaining importance for renewable energy generation. In this study, greenly synthesized Fe-PANI was reported as...

Solution combusted ultrathin Co3O4/CoO heterophase electrocatalyst for solar‐energy driven bifunctional water electrolysis

“…According to the electrochemical results the SCSCO6 become a potent HER electrocatalyst, strong hydrogen adsorption facilitated Volmer and Heyrovsky step and consequently speed up the vigorous H 2 evolution [71] …”

“…According to the electrochemical results the SCSCO6 become a potent HER electrocatalyst, strong hydrogen adsorption facilitated Volmer and Heyrovsky step and consequently speed up the vigorous H 2 evolution. [71] In alkaline, SCSCO6 transformed into Co(OH)x species which absorb water molecules rapidly and released large number of hydrogen atoms as a result of dissociation. These hydrogen atoms adsorbed on active sites of SCSCO6 to form CoÀ H bonds before recombining with water to form hydrogen molecules.…”

A green synthetic approach: crystalline–amorphous interface CoFe-LDH as a sustainable electrocatalyst for water oxidation with low cell voltage and evaluation of its sustainability standards

“…100,101 The environmental impact was compared with previous work (Table S8 †). 10,102,103 The appropriate calculations were carried out using the equations listed in the ESI (ESI-S6). † 3.3.1 Raw materials.…”

“…8,9 The mechanochemical green technique with a pestle and mortar has received great attention due to the scarcity of solvents; it does not necessitate sophisticated laboratory instruments and can be carried out in any laboratory. [10][11][12] Herein, we report a simple, scalable and eco-friendly solvent-decient green strategy for the synthesis of a robust Co/Fe layered double hydroxide (CoFe-LDH) electrocatalyst for the OER process. The solvent-decient green technique provided a crystalline-amorphous interface with a large surface area and high conductivity with excellent OER performance.…”
