A series of Fe₃O₄/Ph-C≡C-Cu magnetic hybrids were synthesized by a repeatable photothermal method in this work. The structure and morphology studies proved that Ph-C≡C-Cu grow on the surface of Fe₃O₄ in a different way, which significantly affected its physical properties and photocatalytic performance. With 4% Fe₃O₄ modification, the photocatalytic degradation rate of high concentration of pentabromophenol (PBP, 3 ×10⁻⁴ M) achieved the highest, which is 6 times higher than those of pure Ph-C≡C-Cu and Fe₃O₄. The degradation of hexabromobenzene (HBB) over Ph-C≡C-Cu was also improved to be twice higher. The excellent photocatalytic activity of Fe₃O₄/Ph-C≡C-Cu can be attributed to the big surface area, high carrier generation, transfer and separation efficiency. The TONs exceed 1 of both PBP and HBB degradation demonstrates real photocatalytic processes.

本工作采用可重复光热法合成了一系列Fe ₃ O _{4 /Ph-C≡C-Cu磁杂化物。}结构和形貌研究证明Ph-C≡C-Cu以不同的方式在Fe ₃ O ₄表面生长，显着影响其物理性质和光催化性能。4% Fe ₃ O _{4改性后，高浓度五溴苯酚（PBP，3×10} ^-4 M）的光催化降解率最高，比纯Ph-C≡C-Cu和Fe高6倍₃ O ₄. 六溴苯 (HBB) 在 Ph-C≡C-Cu 上的降解也提高了两倍。_{Fe 3} O ₄ /Ph-C≡C-Cu优异的光催化活性可归因于大表面积、高载流子产生、转移和分离效率。PBP 和 HBB 降解的 TON 均超过 1，证明了真正的光催化过程。
