Comprehension of the Route for the Synthesis of Co/Fe LDHs via the Method of Coprecipitation with Varying pH

Abstract: Co/Fe-based layered double hydroxides (LDHs) are among the most promising materials for electrochemical applications, particularly in the development of energy storage devices, such as electrochemical capacitors. They have also been demonstrated to function as energy conversion catalysts in photoelectrochemical applications for CO2 conversion into valuable chemicals. Understanding the formation mechanisms of such compounds is therefore of prime interest for further controlling the chemical composition, structu… Show more

“…Transmission electron microscopy (TEM) images showed that the CoFe-LDH–carbon composites had relatively thicker sheet-like layered morphology compared to CoFe-LDH (Figure c–f). The TEM image of CoFe-LDH also revealed the presence of hexagons with some cracks, which results in accordance with the CoFe-LDH growth mechanism (Figure c). , For further clarity, these hexagons are marked by yellow dotted lines in Figure S3a, SI. Interestingly, the TEM image of CoFe-LDH/BUGC revealed significantly thinner morphology compared to CoFe-LDH/IMC or CoFe-LDH/MMC, and hexagons with some cracks were visible due to the formation of CoFe-LDH in CoFe-LDH/BUGC (Figure d–f) and these hexagons are highlighted by yellow dotted lines in Figure S3b, SI.…”

“…Although LDH has excellent intrinsic catalytic activity, its low conductivity will seriously affect electron transfer and reduce catalytic activity and stability [ 3 , 4 , 5 ], even in the widely used binary catalytic systems (such as NiFe-, NiCo-, CoFe-, CoMn-LDHs, etc.) [ 6 , 7 , 8 , 9 ]. It is reported that the electronic structure of a ternary solid solution can be further improved by introducing Co, V, or Mo elements on the basis of a binary catalyst [ 10 , 11 , 12 ].…”

“…LDHs usually contain bivalent and trivalent metal ions like Co(II)/Co(III) and Fe(III)/Fe(II). In the work of Morcos et al [ 10 ], the coprecipitation method was used to prepare Co/Fe-based LDHs. The materials were characterized with different physicochemical techniques, like powder X-ray diffractometry, Fourier Transform Infra-red spectroscopy, Scanning Electron Microscopy, etc.…”
