“…Fe-based metallic glasses, which have great potential in degrading azo dyes and other organic pollutants, have been widely studied as an environmentally friendly wastewater repairing material [6][7][8]. Studies have been carried out on the degradation of azo dyes in aqueous solution by various amorphous alloys, such as Fe-based alloys [9][10][11][12][13][14][15][16][17][18][19], Mg-based alloys [20][21][22], Co-based alloys [23], and Al-based alloys [24], due to their advanced catalytic capability for wastewater remediation. The degradation of azo dyes can be attributed to amorphous or metastable thermodynamic properties of amorphous alloys and the tight surface structure [9,10,16,17].…”

Fe-based amorphous alloys have shown great potential in degrading azo dyes and other organic pollutants. It has been widely investigated as a kind of environmentally friendly material for wastewater remediation. In this paper, we studied the effect of Ni addition on the catalytic performance of Fe87Si5B2P3Nb2Cu1 amorphous alloy for degradation of methylene blue dyes and analyzed the reaction mechanism. (Fe87Si5B2P3Nb2Cu1)86Ni14 amorphous powder with desirable performance was produced by specific ball milling durations. Characterization of the Fe87Si5B2P3Nb2Cu1 and (Fe87Si5B2P3Nb2Cu1)86Ni14 amorphous alloys prepared by ball milling was performed by XRD and SEM. Fe87Si5B2P3Nb2Cu1 and (Fe87Si5B2P3Nb2Cu1)86Ni14 amorphous alloys were used as catalysts to catalyze the degradation of methylene blue dyes, which were detected by UV-VIS near-infrared spectrophotometer. By a series of comparative experiments, it was found that a catalyst dosage of 0.2 g and a reaction temperature of 80 °C were conditions that produced the best catalytic effect. The degradation rate of (Fe87Si5B2P3Nb2Cu1)86Ni14 amorphous alloy to methylene blue dyes prepared by ball milling increased from 67.76% to 99.99% compared with the Fe87Si5B2P3Nb2Cu1 amorphous alloy under the same conditions.

“…Recent reports demonstrate that thin film MGs with enhanced mechanical properties present great potential application in the catalytic research field [10,11]. To date, MGs with various elemental compositions have been widely studied as effective catalysts for industrial effluents treatment [12][13][14][15]. It has been reported that the Fe 78 Si 9 B 13 and Fe 73.5 Si 13.5 B 9 Cu 1 Nb 3 MGs demonstrate 5 -10 times quicker production rate of reactive species than the currently employed Fe-based catalysts [16].…”

“…However, these catalysts still have significant disadvantages, such as low efficiency, less reusable, fast decay, and secondary pollution [21]. Recent reports demonstrate that using MGs as catalysts could effectively overcome the abovementioned shortcomings and their catalytic activity could be much improved by tuning their particle size [32], surface morphology [33], surface to volume ratio [5], and chemical composition [14,15]. For example, the Fe 73.5 Si 13.5 B 9 Cu 1 Nb 3 MGs can be used as an effective catalyst in activation of hydrogen peroxide (H 2 O 2 ) to rapidly generate hydroxyl radicals (•OH) for completely degrading methyl blue and methyl orange within 20 min [16].…”

L. (2018). Fe73.5Si13.5B9Cu1Nb3 metallic glass: Rapid activation of peroxymonosulfate towards ultrafast Eosin Y degradation. AbstractDiscovering functional applications of metallic glasses (MGs) as heterogeneous catalysts is a fundamental and essential topic. This work reports the rapid production of sulfate radicals (SO 4 • − ) from peroxymonosulfate (PMS) using Fe 73.5 Si 13.5 B 9 Cu 1 Nb 3 glassy ribbons as catalysts for Eosin Y (EY) dye wastewater treatment. The reaction rates (k) from the experimental data reveal that the EY degradation is well fitted with the pseudo-first-order kinetic model. The strong electron transfer ability is characterized by electrochemical methods, presenting an advanced catalytic performance for EY degradation. Various experimental parameters, including dye concentration, catalyst dosage, PMS concentration, light intensity, pH and reaction temperature as well as the saline and natural inorganic effects, are fully investigated. The results show that the color removal of EY dye could achieve nearly 100% within 20 min. The quenching experiments are performed to verify the production of reactive species, suggesting that both •OH and SO 4 • − are produced from PMS that play significant roles for EY degradation. This critical study reveals that using Fe 73.5 Si 13.5 B 9 Cu 1 Nb 3 MGs as catalysts exhibit a superior reactivity on PMS activation in wastewater treatment. The discoveries shed lights into the study of electron transfer ability for MGs, presenting extensive prospects in the application of dye wastewater treatment.

Developing new functional applications of metallic glasses in catalysis is an active and pivotal topic for materials science as well as novel environmental catalysis processes. Compared to the crystalline materials with highly ordered atomic packing, metallic glass has a simply disordered atomic structure. Recent reports have demonstrated that the metallic glasses are indeed having many superiorly catalytic properties, yet the understanding of the mechanism is insufficient. In this work, the structural relaxation (α-relaxation) by annealing in an amorphous Fe 78 Si 9 B 13 alloy is studied for unraveling the catalytic mechanism at the atomic scale. The volume fractions of the crystalline structures, such as α-Fe, Fe 2 Si, and Fe 2 B, in the as-received and annealed metallic glasses are fully characterized. It is found that the randomly atomic packing structure with weak atomic bonding in the as-received metallic glass has an efficient electron transfer capability, presenting advanced superiorities in the aspects of production rate of hydroxyl radicals (•OH), dye degradation rate (k), and essential degradation ability (K SA ) for water treatment. The discovery of this critically important work unveils why using metallic glasses as catalysts has higher reactivity than the crystalline materials, and more importantly, it provides new research opportunities into the study of synthetic catalysts.
