MgO as promoter for electrocatalytic activities of Co3O4–MgO composite via abundant oxygen vacancies and Co2+ ions towards oxygen evolution reaction

An advanced PdNPs@MoS2 nanocomposite for efficient oxygen evolution reaction in alkaline media

“…5d. As described in previous studies, 38,40,54 the slope obtained after linear fitting corresponds to the ECSA value. In order, sample-2, sample-1, palladium nanoparticles, and pristine MoS 2 have ECSA values of 20.5, 11, 3.8, and 3.6 μF cm −2 respectively.…”

Facile synthesis of a luminescent carbon material from yogurt for the efficient photocatalytic degradation of methylene blue

“…Both the electrochemical measurements were done according to our previous work. 86 The electrochemical active surface area was calculated by cyclic voltammetry at various scan rates, as shown in Fig. 11a .…”

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

“…5c) and different types of oxygen environments such as lattice oxygen, surface oxygen, and chemisorbed oxygen were observed for both samples. 73 This signal indicates that sample 1 shows major contribution from the oxygen surface (signal at ca. 531 eV), which is normally attributed to surface defects/ vacancies.…”
