Co/N Co-Doped Carbonized Wood for Rhodamine B Degradation
摘要
Abstract
Cobalt-based catalysts have gained considerable attention in the field of water treatment due to the high catalytic activity.However,the application is hindered by challenges such as poor cycling stability and low dispersibility.This study successfully prepared cobalt-nitrogen co-doped carbonized wood through polydopamine modification treatment,followed by impregnation with cobalt salt solution and subsequent carbonization.The synthesized carbonized wood was characterized using X-ray diffraction,specific surface area analysis,Raman spectroscopy,and scanning electron microscopy.Degradation experiments revealed that the cobalt and nitrogen-doped carbon layers in the carbonized wood exhibited synergistic activation,achieving a 99.60%degradation of Rhodamine B within 20 minutes.The research provides insights on the design and preparation of carbonized wood-based supported catalysts.关键词
