Synthesis of nickel – hydroxyapatite by electrochemical method

Abstract

The electrochemical method in two chambers with the bipolar membrane has been used to produce the nickel – hydroxyapatite particle. Hydroxyapatite is used as the supported catalyst for nickel catalyst. In this work, in-situ electrochemical synthesis in two chambers with bipolar membrane has been used in the formation of nickel-hydroxyapatite. A simple electrolysis cell from acrylic was used. The anode and the cathode were set parallel with a distance of 3 cm and immersed in the solution at a depth of 2 cm. The anode and the cathode were connected to a DC power supply. The particle was produced in the electrolysis cell. In the anode chamber, the pH solution decreases for the time of electrolysis while in the cathode chamber the pH solution increases. The nickel – hydroxyapatite particle is formed in the cathode chamber. There is no particle in the anode chamber. At the lower current density, the first formed is brushite. At the higher current density, brushite converts to HA. The higher current density the greater the chances of HA formation. The increase in the initial concentration of NiCl2 accelerates the increase of the pH of the electrolysis solution.

“…On the other hand, the highest crystallinity was observed for sample 1.5 (82.8%), whereas the crystallinity degree of sample 1.0 was 75.1%. On this basis, it can be concluded that the method produces phase-pure and crystalline [55,56].…”

Synthesis of Ni-B/Hydroxyapatite by Electrochemical Method and Its Application as Catalyst on NaBH₄ Hydrolysis

“…In this work, Ni-B catalyst is used as the catalyst and hydroxyapatite as the catalyst support. In previous studies, Ni/hydroxyapatite particles were successfully synthesized electrochemically [11]. The use of bipolar membranes in electrochemical synthesis strongly supported the electrolysis [12,13,14].…”
