Abstract

In this study, a novel photocatalyst, 4-OMe-2,3,5,6-tetrafluorophenyl acetylide copper (TFPACu), was synthesized by introducing more electron-withdrawing groups (−F) onto the benzene ring of PhC₂Cu. The physicochemical properties of TFPACu were investigated using a variety of characterization techniques. The result of Mott-Schottky test suggested that TFPACu is an n-type semiconductor. The active species involved in the photocatalytic degradation process were investigated by electron spin resonance (ESR). The results indicate that OH and h⁺ was the main active species in the photodegradation process. Under natural solar light irradiation, the degradation rate of TC reached 96 % within 30 min. This work will offer a viable idea for the rational design and development of efficient and cost-effective photocatalysts.

用于天然太阳光驱动光催化的 TFPACu 纳米线的合理设计与合成

本研究通过在 PhC2Cu 的苯环上引入更多的电子吸收基团（-F），合成了一种新型光催化剂--4-OMe-2,3,5,6-四氟苯乙酰铜（TFPACu）。研究人员利用多种表征技术对 TFPACu 的理化性质进行了研究。莫特-肖特基测试结果表明，TFPACu 是一种 n 型半导体。通过电子自旋共振（ESR）研究了参与光催化降解过程的活性物种。结果表明，OH 和 h+ 是光催化降解过程中的主要活性物种。在自然太阳光照射下，30 分钟内 TC 的降解率达到 96%。这项工作将为合理设计和开发高效、经济的光催化剂提供可行的思路。

期刊介绍： JPPA publishes the results of fundamental studies on all aspects of chemical phenomena induced by interactions between light and molecules/matter of all kinds. All systems capable of being described at the molecular or integrated multimolecular level are appropriate for the journal. This includes all molecular chemical species as well as biomolecular, supramolecular, polymer and other macromolecular systems, as well as solid state photochemistry. In addition, the journal publishes studies of semiconductor and other photoactive organic and inorganic materials, photocatalysis (organic, inorganic, supramolecular and superconductor). The scope includes condensed and gas phase photochemistry, as well as synchrotron radiation chemistry. A broad range of processes and techniques in photochemistry are covered such as light induced energy, electron and proton transfer; nonlinear photochemical behavior; mechanistic investigation of photochemical reactions and identification of the products of photochemical reactions; quantum yield determinations and measurements of rate constants for primary and secondary photochemical processes; steady-state and time-resolved emission, ultrafast spectroscopic methods, single molecule spectroscopy, time resolved X-ray diffraction, luminescence microscopy, and scattering spectroscopy applied to photochemistry. Papers in emerging and applied areas such as luminescent sensors, electroluminescence, solar energy conversion, atmospheric photochemistry, environmental remediation, and related photocatalytic chemistry are also welcome.
