摘　　要：采用强酸性阳离子交换树脂(R─H),以CuSO4.5H2O为原料,制备出R2─Cu型阳离子交换树脂,R2─Cu型阳离子交换树脂与酒石酸钾钠进行离子交换得到Cu(OH)2,再用葡萄糖还原制得Cu2O纳米粒子,用IR、XRD、BET、TEM等手段对样品进行了表征,并以催化罗丹明B为模拟染料,日光(4月晴天,T=15～25℃)为光源,在自制的无色透明的玻璃反应器进行光催化降解反应,考察了Cu2O纳米粒子的催化性能.Using the strong acid ion-exchange resin （R--H） and CuSO4· 5H2O as raw material, the R2--Cu ion-exchange resin was prepared, then Cu ion on the R2--Cu ion-exchange resin was exchanged with the potassium sodium in tartrate to obtain Cu（OH）2, and then the Cu（OH）2 was reduced to Cu2O nanoparticle by the glucose. The product was characterized by IR, XRD, BET, TEM. The photocatalytic behavior of the CuE O to degradation of rhodamine B was investigated. It was found that 100mL （pH = 6） 50mg L^-1 rhodamine B nearly completely degraded under the solar light （ in April cloudless day, 6h, T=15 - 25 ℃ ）, the existence of 0.4 g Cu2O and lmL 30% H2O2.
