nickel-based one-pot hydrothermal synthesis with organic-metal framework for oer / her bi-functional system

Abstract: many researches have recently been reported on metal-organic frameworks in various fields. metal-organic frameworks (mofs) are composed of central metal ions and ligands. they have easily adjustable structural chemistry and selective metal ions as distributed active sites. recent studies have shown that mof can provide a desirable improvement in catalytic performance as a promising precursor to the synthetic process of non-noble metal catalysts. in addition, recent research on nickel-based mofs as electrocatalysts has been widely discussed, suggesting that ni-based mofs can react with oxygen. however, finding a higher activity for a mof catalyst that could be better than a pt / c catalyst is still challenging [1-3]. currently, most fuel cells use pure oxygen or air oxygen as the oxidizing agent. as an example of a natural fuel cell, consider a hydrogen-oxygen fuel cell with an aqueous alkaline or acid electrolyte and its specific properties. the reactants are gaseous in a hydrogen-oxygen fuel cell with a liquid electrolyte. under these conditions, porous gas-emitting composites are used in cells, where metal-organic template composites use suitable porosity to absorb gases. in the present work, nickel nitrate in nitrogen-doped mesoporous carbon (nmpc) [4], obtained from citric acid (ca) and triethylamine (tea), in a liquid fuel cell (0.1m naoh as a liquid electrolyte) in the anodic area for oxygen evolution reaction (oer) and cathodic area for hydrogen evolution reaction (her) in linear sweep voltammetry (lsv) for an excellent her / oer bi-functional system [5] have been reported , which have shown perfect performance. the starting potential point for oer 1.436v and her 0.0066v has been observed that the optimum performance of this bi-functional system is comparable to that of synthesized electrocatalysts so far. furthermore, for characterization, ft-ir and xrd analysis were used to better recognize the composite and fesem for observed the morphology and size of the synthesized particles.
