Abstract:
Two different methods were used to immobilize Co corroles on carbon nanotubes (CNTs) through covalent bonds. The resulting CNTs engineered with Co corroles were used as electrocatalysts for the hydrogen evolution reaction (HER) and the oxygen evolution reaction (OER) in aqueous solutions of pH 0, 7, and 14. For both HER and OER in all solutions, the hybrids obtained by attaching Co corroles on CNTs through amidation coupling showed better performance. This is likely because the large surface area and good electrical conductivity of CNTs can be well preserved during the amidation reaction under mild conditions.

Covalent Bonds
Covalent Bonds
When two atoms share electrons to complete their valence shells, they create a covalent bond. An atom's electronegativity—the force with which shared electrons are pulled towards an atom—determines how the electrons are shared. Molecules formed with covalent bonds can be either polar or nonpolar. Atoms with similar electronegativities form nonpolar covalent bonds; the electrons are shared equally. Atoms with different electronegativities share electrons unequally,...

Hydrogen Bonds Control the World!
Because hydrogen has very weak electronegativity when it binds with a strongly electronegative atom, such as oxygen or nitrogen, electrons in the bond are unequally shared....
