Complexes and preipitates of nickel (II) are formed by adding ammonium hydroxide, ethylenediamine, and dimethylglyoxime to dilute solutions of Ni2+ in beakers. Cyanide salts and solutions are ...

What makes this achievement remarkable is the use of inexpensive nickel compounds for the anode catalyst, replacing costly and rare iridium. At BESSY II, the team was able to elucidate the ...
