| 摘要: |
| 为实现特定形貌CuO纳米材料的温和可控合成,增强该材料作为电化学催化剂的催化活性,利用亚铜离子在碱性溶液中的氧化沉淀反应,制备了形貌均一稳定的CuO纳米片层。采用粉末X射线衍射、扫描电子显微镜、透射电子显微镜、X射线光电子能谱与电化学催化反应等手段,研究了不同合成参数对产物的形貌、价态与电化学催化性能的影响。研究结果表明:当产物投料比为0.01 g CuCl/10 mL TBAOH时,产物的电化学催化性质最好；在200 ℃下煅烧后,催化性能得到进一步提高。利用具有特殊分子结构的四丁基氢氧化铵作为模板剂,能够实现CuO纳米片层的简单、快速、温和制备；同时,产物中低价态Cu离子的存在可提高催化剂的电化学催化活性。通过煅烧提高产物的结晶性,能够进一步增强材料的电化学催化活性。 |

| Abstract: |
| To realize gentle and controllable synthesis of CuO nanomaterials with specific morphology and enhance the catalytic activity of CuO as an electrochemical catalyst, CuO nanosheets with uniform and stable morphology were prepared by the oxidation precipitation reaction of Cu+ in alkaline solution. By using powder XRD, SEM, TEM, XPS, and electrochemical catalytic reaction, the morphology, valence, and electrochemical catalytic performance of the product with different synthesis parameters (ratio of raw materials, calcination temperature) were studied. Results show that the catalytic performance was the best when the ratio of raw materials was set as 0.01 g CuCl/10 mL TBAOH.Moreover, through the calcination process at 200 ℃, the catalytic performance was further improved. The conclusion shows that the addition of TBAOH with a special molecular structure as a template agent can realize simple, fast, and gentle synthesis of CuO nanosheets. Meanwhile, the presence of Cu+ ions in the product can improve the electrochemical catalytic activity of the CuO nanosheets. By increasing the crystallinity of the products through calcination, the electrochemical catalytic activity of the products can be further enhanced. |
