Iron (III) oxide, Nickel (II) oxide, Cobalt (II) oxide, Methyl Orange and Methylene blue are from Alfa Aesar (China), and Methyl blue is from Sigma-Aldrich (China). All chemicals are of analytical grade. All solutions are prepared with deionized water. The laser irradiation in liquid technique has been reported in our previous works18 19 20 21 (link)22 (link)23 (link)24 25 (link)26 . In this case, 5 mg metal oxide nanoparticles powder with a purity of 99.99% is firstly placed in a glass bottle filled with 10 ml of deionized water. Magnetically-stirred operation is to make the powder monodisperse in water. Then, the aqueous solution is irradiated by a Q-switched Nd:YAG laser device with a wavelength of 532 nm, repeating frequency of 10 Hz, pulse width of 10 ns, energy density of 400 mJ/pulse and spot size of 4 mm in diameter. During laser irradiating, the liquid environment is maintained at ambient temperature and pressure. The laser irradiation process lasts for 30 min. Then, the colloidal solution is synthesized and then collected in a cuvette for measurements.

About PubCompare
Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.
We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.
However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
