WebApr 14, 2024 · Owing to the superthin and amorphous structure, the ANH catalyst can be oxidized to NiOOH at a much lower potential than conventional Ni(OH) 2 and finally exhibits more than an order of magnitude higher current density (640 mA cm −2), 30 times higher mass activity, 27 times higher TOF than those of Ni(OH) 2 catalyst. The multistep … WebSep 14, 2024 · Amorphous solids are pseudo solids, and they have ions, atoms, or molecules that are irregularly organized. However, crystalline solids are true solids, and they have particles that are arranged orderly in a crystal lattice. Amorphous solids are isotropic. They show the same value of properties in all directions.
