Tin (Sn2+) ions incorporated hydroxyapatite (HAp) nanospheres were prepared by wet chemical, leading to enhanced specific capacitance and excellent cyclic stability for electrochemical energy storage applications.
Tin (Sn2+) ions incorporated hydroxyapatite (HAp) nanospheres are prepared by wet chemical. The Sn2+ ions lead to reduce crystallite size with modified vibration groups. The nanosphere is achieved on incorporation. The surface area and pore diameter are enhanced at low Sn2+ ions (11.29%). The specific capacitance (231 F g(-1) at 3 mAg(-1)) (230%) is augmented at higher incorporation (27.27%) compared to pristine. The 100% cyclic stability up to 800 cycles is achieved. Here, the correlated partial amorphization, atomic disorder and surface properties are realized. Thus, the tin-calcium phosphate demonstrates an outstanding candidate for electrochemical energy storage application. (C) 2020 Elsevier B.V. All rights reserved.
