摘要:
采用共沉淀法制备CO32–为层间阴离子的Zn–M–Cr–CO3–HTLCS(类水滑石)三元类水滑石样品,Zn2+、M2+、Cr3+摩尔比为1.5︰1.5︰1.0,M=Mg、Mn、Co、Ni、Cu。用X射线衍射、红外光谱、热重–差热分析和紫外–可见漫反射光谱等分析技术对三元类水滑石的结构和性质进行表征。结果表明:不同二价金属阳离子取代的5种三元类水滑石都具有水滑石的典型层状结构。取代二价金属阳离子半径越小,晶胞参数a值也越小,三元水滑石热稳定性越好。考察了光照时间和催化剂种类、用量等因素对三元类水滑石光催化降解罗丹明B(RhB)溶液的影响,讨论了光催化降解RhB的反应机理。结果表明:Zn–Ni–Cr–CO3–HTLCS的光催化性能最好,其用量为0.1 g/50 mL条件下,光照120 min,RhB的降解率达到90.72%,循环使用4次后,对RhB的降解率保持在90%左右,且催化剂晶体结构不变。
 

 

 Carbonate pillared hydrotalcite-like compounds of Zn–M–Cr–CO3–HTLCS(hydrotalcite-like compounds) (Zn2+/M2+/Cr3+ atomic ratio of 1.5: 1.5: 1.0 and M: Mg, Mn, Co, Ni, Cu) were synthesized by a co-precipitation method. The structures and properties of Zn–M–Cr–CO3–HTLCS were characterized by X-ray diffraction (XRD), Fourier transform infrared spectrometry (FT-IR), thermogravimetry analysis-differential scanning calorimetry (TG-DTA) and UV-visible diffuse-reflectance spectroscopy (UV-Vis DRS), respectively. Based on the XRD and FT-IR analysis, five kinds of different cationic substituted Zn–M–Cr–CO3–HTLCS have a typical layered structure of layered double hydroxides intercalated with carbonate. The value of lattice parameter a decreases, but the thermal stability of hydrotalcite increases at the smaller ionic radius of substituted divalent metallic cations. The photocatalytic activities of Zn–M–Cr–CO3–HTLCS were examined with Rhodamine B (RhB) and the photodegradation mechanism was also discussed. The results show that the optimum photocatalytic performance of Zn–Ni–Cr–CO3–HTLCS can be obtained. The degradation rate of the Zn–Ni–Cr–CO3–HTLCS for RhB under the light irradiation for 2 h is 90.72% when the dosage of Zn–Ni–Cr–CO3–HTLCS is 0.1 g/50 mL, and is still 90% after reused for four times.
