摘要

摘要 通过用 Cacumen Platycladi 提取物还原 HAuCl4 制备了一种支撑金催化剂。然后将该催化剂用于模型反应中 2-苯乙醇的氧化。我们的研究评估了各种制备条件的影响,包括金负载率和煅烧温度。此外,我们还探讨了反应温度和反应时间对金/二氧化钛催化剂催化性能的影响。实验结果表明,金负载率为 1.3 wt %、煅烧温度为 400°C 的 Au/TiO2 催化剂的催化效果显著。在特定的反应条件下(0.3 克催化剂、220°C、3.0 兆帕、2.5 小时),2-苯基乙醇的转化率达到 45.3%,目标产物(苯乙醛)的选择性为 59.6%,产率为 27.0%。此外,催化性能在重复使用 8 次后仍然保持稳定。

Preparation of the Au/TiO2 Catalyst for the Oxidation of 2-Phenylethyl Alcohol using a Cacumen Platycladi Extract as a Reducing Agent

A Supported gold catalyst was prepared by reduction of HAuCl4 with the Cacumen Platycladi extract. This catalyst was then used for oxidation of 2-phenylethyl alcohol in a model reaction. Our study evaluated the effect of various preparation conditions, including the Au loading ratio and calcination temperature. Additionally, we explored the influence of the reaction temperature and reaction time on the catalytic performance of a Au/TiO2 catalyst. Our experimental findings revealed notable results for the Au/TiO2 catalyst characterized by the Au loading of 1.3 wt % and calcinated at 400°C. Under specific reaction conditions (0.3 g catalyst, 220°C, 3.0 MPa, 2.5 h), the conversion of 2-phenylethyl alcohol reached 45.3 and a 59.6% selectivity and a 27.0% yield of the target product (phenylacetaldehyde). In addition, catalytic performance remained stable after 8 repeated uses.

期刊介绍: Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
