本篇文章主要在探討鈀奈米粒子的表面電漿共振性質並試圖藉由參雜鎘原子來提升其表面電漿共振的性質。在本論文中我們合成了53奈米的鈀立方體、10奈米的鈀立方體及10奈米的鈀鎘立方體合金。我們分別照射不同波長的光進行鈴木耦合反應,以53奈米的鈀立方體為催化劑時,分別照射385 nm波長的光,用來同時激發表面電漿共振以及電子能帶(d-band)間的躍遷,及照射 625 nm波長的光,用來單純激發電子能帶(d-band)間的躍遷,藉此來得知鈀奈米粒子表面電漿共振的能力。此外,在紫外可見光光譜圖中發現到10奈米鈀鎘合金比起10奈米鈀立方體在370 nm處有個訊號峰,並將兩者進行光催化比較,發現到在照射385 nm的光時,以10奈米鈀鎘合金為鈴木耦合催化劑所生成的聯苯產率有明顯提升。
This article is mainly to explore the localized surface plasmon resonance (LSPR) property of the Pd nanoparticles, and try to dope the Pd nanoparticles with Cd atoms to enhance the LSPR performance. We synthesized 53 nm of Pd nanocubes、10 nm of Pd nanocubes, and 10 nm of PdCd nanocubes . Photocatalysis of Suzuki coupling reactions by the 53 nm of Pd nanocubes with different wavelengths of light was done to understand how strong the Pd nanoparticle LSPR ability is. The wavelength of 385 nm wavelength was used to simultaneously excite the LSPR and the interband transition, while the wavelength of 625 nm was used to excite only the interband transition. In comparison with the 10 nm of Pd nanocubes, we found that there is a peak around 370 nm in the UV-Visible spectrum of the 10 nm of PdCd nanocubes. In photocatalysis, the 10 nm of PdCd nanocubes showed a significantly improved yield of biphenyl than the 10 nm of Pd nanocubes by illuminating with the light wavelength of 385 nm.
