摘　　要：The design and synthesis of self-suspending photocatalyst device with easy recyclability is important for practical application.Here,this work utilizes aluminum-plastic package waste as raw material to prepare an aluminum-plastic supported TiO_(2)(AP-TiO_(2))photocatalyst device through 3D printing design and surface deposition method.A series of characterizations were carried out to explore the structure,morphology and performance of the AP-TiO_(2)device.Under UV light illumination,the AP-TiO_(2)-50 efficiently degrade 93.6%tetracycline hydrochloride(THC)after 4 hr,which increases by 8.3%compared with that of TiO_(2)powder suspension system with the same catalyst amount.Based on it,AP-ZnO,AP-CdS,AP-g-C_3N_4and AP-Pt-TiO_(2)are also fabricated,and applied in photocatalytic degradation and hydrogen evolution,which all exhibit higher photoactivities than powder suspension systems.This work provides a new avenue for the fabrication of advanced recyclable photocatalyst device.Moreover,the work offers a novel sight for the high-value utilization of aluminum-plastic package waste,which has positive implications for environmental protection.
