以CuSO4为铜源，Na2SO3和葡萄糖为共还原剂，在pH5的HAc-NaAc缓冲溶液中，使用微波辐射法一步、绿色、快速合成活性炭负载氧化亚铜（Cu2O/AC）可见光响应光催化剂.利用X-射线衍射仪、扫描电子显微镜、能谱仪以及X-射线光电子能谱仪对制备的Cu2O/AC进行表征，结果表明，制备的Cu2O为纯相,并呈放射状花型形貌.催化剂光催化罗丹明B降解效率在不外加任何氧化剂条件下，利用溶液中的自然溶解氧，反应2.5 h其降解率可达到62.5%，在有微量氧化剂H2O2存在下，30 min即可基本降解完全，且负载型催化剂可非常方便地回收、多次重复使用，符合清洁生产的绿色化发展方向.

The photocatalyst of active carbon loaded cuprous oxide(Cu2O/AC)was prepared with green,fast method in HAc-NaAc buffer solution(pH 5)under microwave radiation condition taking CuSO4 as source of copper,Na2SO3 and glucose as co-reducing agents.The Cu2O/AC was characterized by X-ray diffraction,scan?ning electron microscope,energy spectrometer and X-ray photoelectron spectrometer.The results showed that as-prepared Cu2O was of pure phase and radiated pattern morphology.The efficiency of photocatalytic degra?dation rhodamine B could reach 62.5% for 2.5 h reaction using the natural dissolved oxygen in the solution in the absence of any oxidant.The rhodamine B could be degraded almost completely for 30 min reaction in the presence of trace oxidant H2O2.The photocatalyst of active carbon loaded cuprous oxide could be re?trieved easily,and be used repeatedly in accordance with clean production of green development direction.
