The metastable energy state and abundant active sites in Fe-based amorphous alloys (FAAs) make them promising catalysts. Surface atomic states may affect the catalytic performance of FAAs, in addition to their internal long-range disordered atomic structure. This paper investigates how laser surface processing affects the phenol degradation performance of industrial Fe₇₈Si₉B₁₃ amorphous ribbon. Appropriate laser processing significantly improves phenol degradation performance. In particular, 40 W laser processing leads to the most pronounced improvement in kinetic rate, reaching 0.82 min⁻¹—much higher than that of previous Fe-based catalysts, even at lower catalyst dosage. Moreover, the degradation rate remains above 98% after 18 cycles. The enhanced degradation is attributed to lower activation energy, abundant active sites, and increased ·OH generation under suitable laser processing. This study reports improved phenol degradation performance of Fe-based amorphous ribbon via laser processing and reveals the underlying mechanisms, providing a feasible strategy for developing efficient and durable FAA catalysts for treating phenol-containing wastewater.
