Abstract
The comprehensive utilization of the excellent magnetic properties and advanced catalytic ability of Fe-based amorphous alloys (FAAs) is reported for the first time. A novel Fe63Cr5Nb4Y6B22 (at%) amorphous alloy that has ferromagnetic to paramagnetic transition near room temperature and good catalytic performance for methylene blue degradation is successfully synthesized. The alloy is applicable for automatically recycled dye degradation with its thermal-tuning magnetic behavior. When an external dye wastewater is applied (high temperature), the FAAs are paramagnetic and disperse into water to participate in degradation. When the wastewater has been degraded and the temperature drops to room temperature, the FAAs change to ferromagnetic and the remediated water can be released. This alloy exhibits a low thermal activation energy barrier of 21.8 kJ/mol due to the reduced atomic bonding forces with Cr addition, and has excellent catalytic performance at high temperature (323
