A Facile electrochemical and chemical Synthesis of Nickel–Cobalt Metal Organic Frameworks on Layered double hydroxides Nanosheets

In recent years, most researchers are looking for methods that at the lowest cost and the best efficiency in the synthesis of materials with the best performance in practical applications [sensing devices (sensors), catalytic coatings, etc.]. Therefore, The present work, we have designed Ni-Co metal-organic frameworks (Ni-Co/LDH-MOFs) with two-dimensional (۲D) layered double hydroxides (LDH) through in-situ growth simple electrochemical and chemical method at under recommended storage conditions(NaCl=۱۰%) [۲]. In the next step, representative composites were characterized by means of FTIR, SEM and XRD techniques. In electrochemical studies, Ni-Co/LDH-MOFs were employed as excellent modifiers on the surface carbon ceramic electrode (CCE) through drop casting method (Ni-Co/LDH-MOFs/CCE) to investigate the analytical performance of Formaldehyde with different electrochemical methods. Then, the Ni-Co/LDH-MOFs/CCE was used for the electrocatalytic oxidation of Ni-Co/LDH-MOFs/CCE in alkaline media[۳]. In the next step, the kinetic parameters of the electron transfer coefficient (α) and number of electrons involved in the rate determining step (nα) for the oxidation of Ni-Co/LDH-MOFs/CCE were determined using cyclic voltametry. The anodic currents showed a linear dependence on the concentration of Formaldehyde. The findings demonstrated that the synthesis of Metal-Organic Frameworks MOFs by using LDH materials enhanced the electrocatalytic performance of the synthesized nanocatalysts. This advancement paves the way for the development of high-performance electrocatalysts suitable for use in direct Formaldehyde fuel cell systems
