Structural phase stability and homogeneity enhancement of electrochemically synthesized Mn 2V 2O 7 by nanocarbon networks
Original language description
Structural phase stability and homogeneity of the electrochemically synthesized Mn2V2O7 (MVO) on nanocarbon network structures are investigated. The cup-stacked multi-walled carbon nanotubes (CNTs) and electrolytic graphene oxide (eGO) are the networks exploited in present work. It is shown that co-electrodeposition of carbonaceous network and V2O5.nH(2)O followed by electro-insertion of Mn2+ cations results in the formation of intermixed beta-Mn2V2O7 nano-structures. The morphology and surface chemistry of the synthesized nano-structures is studied via high-resolution electron transmission and scanning X-ray photo-emission microscopies as well as Raman spectroscopy. The synthesized MVO on carbon fiber surface in the absence of the nanocarbon network shows a non-uniform phase formation and uneven coating distribution. The nanocarbon networks assisted MVO demonstrate uniform phase formation and distribution. The dominant MVO structural phase product present in these samples differs with different type of carbonaceous networks. The possible effect of the catalytic activity of the carbonaceous network as well as their hydrophilicity on the final structural and phase formation is discussed. The present study establishes new possibilities on catalytic assisted metal alloy oxide deposition for advanced applications. (c) 2022 The Author(s). Published by Elsevier Ltd.
