Abstract
Transitional metal oxide nanoparticles as advanced environment and energy materials require very well absorption performance to apply in practice. Although most metal oxides are based on crystalline, high activities can also be achieved with amorphous phases. Here, we reported the adsorption behavior and mechanism of methyl blue (MB) on the amorphous transitional metal oxide (Fe, Co and Ni oxides) nanoparticles, and we demonstrated that the amorphousization of transitional metal oxide (Fe, Co and Ni oxides) nanoparticles driven by a novel process involving laser irradiation in liquid can create a super adsorption capability for MB, and the maximum adsorption capacity of the fabricated NiO amorphous nanostructure reaches up to 10584.6 mgg−1, the largest value reported to date for all MB adsorbents. The proof-of-principle investigation of NiO amorphous nanophase demonstrated the broad applicability of this methodology for obtaining new super dyes adsorbents.

Methyl blue (MB) is one of the most common dyes which is widely used as the coloring agent and disinfector in pesticides, pharmaceuticals, dyestuffs and varnishes[14,15,16], and it is generally adopted as a representative organic pollutant to test the adsorption performance for the removal of organic contaminants from wastewater
Summary
State Key Laboratory of Optoelectronic Materials and Technologies, Nanotechnology Research Center, School of Physics & Engineering, Sun Yat-sen University, Guangzhou 510275, Guangdong, P. Our measurements indicate that the maximum adsorption capacity of the fabricated amorphous nanostructures of metal oxide nanoparticles for MB is beyond 104 mgg[21] and high up to 10584.6 mgg[21], which is the largest value reported to date for all MB adsorbents. These findings promote the application of amorphous nanostructures as advanced adsorbent materials
