Facile doping of nickel into Co₃O₄ nanostructures to make them efficient for catalyzing the oxygen evolution reaction

Abstract

Designing a facile and low-cost methodology to fabricate earth-abundant catalysts is very much needed for a wide range of applications.

Triazine/thiophene‐based microporous organic polymer for electrocatalytic hydrogen evolution reaction

“…The optimum sample's swift charge transfer capacity may be due to the extended conjugated electronic structure of the organic building blocks and the Ni co‐catalyst. Warburg impedance was not found in the low‐frequency zone, confirming the absence of diffusion‐limited electrochemical reaction on the electrode surface 48,49 . The resistance values obtained for Ni@MOP electrocatalysts were listed in Table S2.…”

Engineering nanostructured Ag doped α-MnO2 electrocatalyst for highly efficient rechargeable zinc-air batteries

“…This evidence clearly indicated that the optimum doping of Ag onto MnO 2 is 7.5 mmol. Moreover, compared with O 2 saturated and unsaturated Ag–MnO 2 -7.5 modified electrode, the peak current of Ag/MnO 2 /GCE was increased dramatically after O 2 saturatation and the peak potential shifted to the more positive value ( Figure 6 c) [ 38 ]. Moreover, for bare GCE and MnO 2 electrode, the onset potential for oxygen reduction is -0.28 V and -0.25 V vs. Ag/AgCl correspondingly.…”

Facile synthesis of efficient Co3O4 nanostructures using the milky sap of Calotropis procera for oxygen evolution reactions and supercapacitor applications

“…Furthermore, the OER performance was evaluated, and the recently published results of the OER are given in Table 2. [78][79][80][81][82][83][84][85][86][87][88][89][90][91][92][93][94][95][96][97] It is obvious that the presented approach is facile, low cost, and efficient in terms of low overpotential, environmental friendliness and scale up for the fabrication of electrocatalyst materials.…”
