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 (Lix)[Ni0.66Mn0.34(OH)2](NO3)·mH2O, Lix[Ni0.67(2+)Co0.33(2+)(OH)2](NO3)0.25(ORO)0.35·mH2O, 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.
