Popis:	Diverse transition metal hydroxide nanostructures were synthesized by laser-induced hydrolysis in a liquid precursor solution for alkaline oxygen evolution reaction (OER). Several active OER catalysts with fine control of composition, structure, and valence state were obtained including (Li_x)[Ni_(0.66)Mn_(0.34)(OH)_2](NO_3)(CO_3) · mH_2O, Li_x[Ni_(0.67)Co_(0.33)(OH)_2](NO_3)_(0.25)(ORO)_(0.35) · mH_2O, etc. An operate overpotential less than 0.34 V at current density of 10 mA cm^(–2) was achieved. Such a controllable laser–chemical route for assessing complex nanostructures in liquids opens many opportunities to design novel functional materials for advanced applications.
