The electrochemical synthesis of hydrogen peroxide (H2O2), a {widely|extensively|broadly} {used|utilized|employed|utilised|applied|made use of} oxidant, is emerging as a green {alternative|option} {to the|towards the|for the} {conventional|standard|traditional} anthraquinone {method|technique|approach|strategy|system|process}. {In this|Within this} {work|function|perform|operate}, Ni-based metal-organic nanosheet (Ni-MONs) catalysts constructed {using|utilizing|making use of|employing|working with|applying} {a variety of|a number of|many different|various|a range of|several different} linkers {were|had been|have been} studied as oxygen reduction catalysts. {Using|Utilizing|Making use of|Employing|Working with|Applying} a host of analytical {techniques|methods|strategies|tactics|approaches|procedures}, we reveal how modulating the terephthalic acid linker with hydroxy, amine, and fluorine groups impacts the resulting physical and electronic structure {of the|from the|in the|on the|with the|of your} Ni catalytic {sites|websites|web sites|internet sites|web-sites|web pages}.
