**2.4. Synthesis of Cu3(BTC)2(H2O)3**

For the synthesis of the Cu3(BTC)2 MOF, a Cu powder metal (99.5%) was used as a target for the ablation dispersed in a solution of a DMF/H2O (1:1) containing the organic linker benzene 1,3,5, benzene tricarboxilic acid and NaNO3 as a hydroxyl radicals (•OH) precursor. The target was ablated for 60 min under magnet stirring with the second harmonic of a pulsed Nd:YAG laser. Soon after the ablation starts, the solution changes its color and a blue precipitate occurs. Finally, the products were centrifuged and collected for sample characterization [20].
