New Nanoporous Findings from Beihang University Reported (Enhanced degradation of azo dye by nanoporous-copper-decorated Mg-Cu-Y metallic glass powder through dealloying pretreatment)

By a News Reporter-Staff News Editor at Science Letter -- Investigators discuss new findings in Nanoporous. According to news reporting originating from Beijing, People's Republic of China, by NewsRx correspondents, research stated, "A controllable uniform nanoporous copper (NPC) layer was synthesized on the surface of the ball-milled powder of Mg65Cu25Y10 metallic glass by dealloying. The morphology, the elemental surface composition and the phase structure of the powders were characterized by scanning electron microscopy, energy dispersive X-ray spectroscopy and X-ray diffractometry, respectively."

Our news editors obtained a quote from the research from Beihang University, "The composite powder with a core-shell structure shows higher degradation efficiency of the azo dye of Direct Blue 6 than the untreated powder and the pure NPC. The improved performance can be attributed to the strong synergistic effect between the NPC layer and the metallic glass matrix, because the nanoporous structure provides large surface area for the adsorption of the dye molecules and three-dimensional diffusion channels of reaction masses, as well as the dissolution acceleration of the active atoms through local galvanic cell reaction."

According to the news editors, the research concluded: "This tunable pretreatment is a promising surface activation method for novel chemical applications of metallic glasses."
