Remarkably enhanced Fenton-like catalytic activity and recyclability of Fe-based metallic glass by alternating magnetic field: mechanisms and industrial applications

Abstract

Fenton-like processes by heterogeneous catalysts present a promising strategy for ever-growing water pollution problems. However, developing low-cost catalysts with sustainability in both high catalytic efficiency and good recyclability remains challenging....

Synergistic enhancement of hydrogen interactions in palladium–silicon–gold metallic glass with multilayered graphene

“…Metallic glasses (MGs) exhibit an exclusive combination of characteristics, i.e., when compared to crystalline counterparts, nanostructured MGs have higher potential for passivation along with lower passivation current, high catalytic efficiency, outstanding mechanical strength and elastic limit, as well as remarkable wear and fatigue resistance. [1][2][3][4][5][6][7][8][9][10] Compared to crystalline metallic alloys, the non-translational atomic clusters constituting MGs on the nanometer scale and the free volume in between enable a higher number of hydrogen interactions. 11,12 Hence, these materials have been suggested as green energy materials for hydrogen storage and production.…”

Rapid fabrication of nanoporous iron by atmospheric plasma for efficient wastewater treatment

“…However, there remains some shortcomings for ZVI in industrial organic wastewater treatment, among which the insufficient activity of iron is the most concerned issue. Various attempts have been made to settle the problem in previous works [6][7][8][9]. An effective way to improve the degradation performance is to increase the specific surface area [2,[10][11][12].…”

Magnetic field driven catalysis of multiferroic magnetoelectric nanocomposites

“…In general, introducing an external field (e.g., thermal, electric, magnetic, and mechanical) would lead to improved efficiency of an existing catalytic system. [1][2][3][4][5][6] Among reported routes, the employment of a magnetic field has been considered as an effective strategy, and significant advances have been achieved in different catalysis fields, including photocatalysis, [7][8][9][10][11] electrocatalysis, [11][12][13][14][15][16][17] and thermocatalysis, [18] leading to significantly enhanced performance and allowing for wireless control of catalytic reactions. [19,20] It is concluded that magnetic fields can affect the spin polarization of magnetic materials, thereby accelerating the movement of free charge carriers and increasing the rate of electron transfer to the surface and generation of free radicals participating in catalytic reactions.…”
