Electronic modulation of cobalt–molybdenum oxideviaTe doping embedded in a carbon matrix for superior overall water splitting

“…2f ), further indicating that Te had been successfully incorporated into the CoMoO 3 lattice. 57,58 The Co 2p spectra of Te-CoMoO 3 @C and CoMoO 3 @C show that the characteristic peaks of Co 2+ 2p 3/2 and Co 2+ 2p 1/2 can be observed at binding energies of 780.89 and 796.67 eV with two satellite peaks at 785.18 and 802.57 eV (Fig. 2g).…”

Anchoring Ce-modified Ni(OH)2nanoparticles on Ni-MOF nanosheets to enhances the oxygen evolution performance

“…The durability of the catalyst is an important factor in determining its practical application. 48 The durability of Ce-m-Ni (OH) 2 @Ni-MOF was evaluated in chronoamperometric mode at 100 mA cm −2 (Fig. 4e), and the result shows no noticeable loss of current density after 30 h. Furthermore, the LSV curve after 5000 CV cycles is almost the same as the initial one (Fig.…”

Electrodeposited bimetallic microporous MnCu oxide electrode as a highly stable electrocatalyst for oxygen evolution reaction

“…Thus, the Mn and Cu oxides in the catalyst can efficiently facilitate the charge transport across the electrode/electrolyte interface. 27,28,45,46 The deconvoluted O 1s spectrum can be fitted into three peaks as shown in Figure 2D. The peak located at 530.39 eV is associated with the oxygen binding to metals such as Mn and Cu, whereas the peak at 531.69 eV is due to the defects and presence of the surface species, including hydroxyls, chemisorbed oxygen, or under-coordinated lattice oxygen.…”

“…We have carried out an extensive literature survey on the low-cost bimetallic electrocatalysts for OER (please see Table Data S1). [14][15][16][17][18][19][20][21][22][23][24][25][26][27][28] The better catalytic results may be endorsed due to the maximum surface defects, which can act as active catalytic sites, supporting the catalyst surface as an intermediate for the adsorption. In the past literature, noticeable developments have been made toward progress in transition metal-based electrocatalysts for the OER.…”
