6 sty 2024 · The results show that Co–Mo (18%) /A-Co(OH) 2 has the smallest Tafel slope of 69 mV dec −1, lower than Co–Mo (18%) (84 mV dec −1) and Co–Mo (18%) /β-Co(OH) 2 (109 mV dec −1).
13 gru 2019 · It is shown that a hollow CoMoO 4-Co(OH) 2 precursor can be formed by the reaction of ZIF-67 with Na 2 MoO 4 32. The formation of Co(OH) 2 can be ascribed to the reaction of OH − in Na 2...
1 mar 2024 · Herein, using the dissolution of Mo in electrolysis, we firstly developed a feasible method to prepare an amorphous-crystalline MoO x /Co (OH) 2 interfacial electrocatalysts with high activity and corrosion resistance on nickel foam (MoO x /Co (OH) 2 /NF).
1 lut 2024 · For pure Co@NC and Mo 2 C@NC, Co nanoparticles encapsulated in carbon nanotubes (Co@NC) can be observed (Fig. S2). Compared with the achieved rod−like structure of the MoO 3 sample (Fig. S3 a−3b), the Mo 2 C@NC sample still maintains the structure assembled by Mo 2 C nanoparticles (Fig. S3 c−3d).
Summary. MO Theory. MO diagrams can be built from group orbitals and central atom orbitals by considering orbital symmetries and energies. The symmetry of group orbitals is determined by reducing a reducible representation of the orbitals in question.
17 mar 2022 · Key mechanistic steps for selective CO(2) reduction over Cu into hydrocarbon versus oxygenated C2 products are identified by atomistic and microkinetic modeling.
Herein, we report a single step, anionic surfactant-assisted, low temperature-hydrothermal synthetic strategy of CoO nanoparticles anchored on β-Co (OH)2 nanosheets which show a low overpotential (295 mV @ 10 mA cm−2) for the oxygen evolution reaction (OER).
