Use of the noble metal nanoparticles in the surface-enhanced resonance Raman spectroscopy (SERRS) is a significant part the measurement. These nanoparticles are often used for SERRS measurements of silver nanoparticles prepared by reduction methods. From the literature it is obvious that the most popular methods of preparation of Ag nanoparticles are procedures which are using the chemical reduction and/or laser ablation. In this paper we discuss the comparison of SERRS spectra of water-soluble porphyrins (TTMAPP and TMPyP) in systems with Ag nanoparticles prepared by chemical reduction with sodium borohydride, sodium citrate and glucose. The comparison of different systems gives insight into the option of suitableility of using of nanoparticles with various surface ions in the production of different spectral forms of chosen porphyrins in dependence on their structures.

Acoustic Levitation

By the deposition of noble metal nanoparticles on a metal oxide substrate with a specific micro-/nanostructure, namely, yolk-shell structure, a remarkable improvement in photocatalytic performance can be achieved by the composites. Nevertheless, noble metal nanoparticles only distribute on the surface shell of metal oxide substrates when the conventional wet-chemistry reduction approach is employed. Herein, we proposed a novel acoustic levitation synthesis of Pt nanoparticles deposited on yolk-shell La2O3. The composites not only displayed well-defined, homogeneous distribution of Pt NPs on the exterior shell of La2O3 and the interior La2O3 core, but an enhanced chemical interaction between Pt and La2O3. The unique structure not only can display improved photocatalytic degradation rate toward methyl orange, but also may show great potential in fields of hydrogen generation, environmental protection, etc. The novel acoustic levitation synthesis can supplement the methodology of synthesizing well dispersed noble metal oxides over the whole yolk-shell structure through noble metal NPs deposition method.
