The synthesis of hybrid silver/zinc oxide (Ag/ZnO) decoration on the cellulose surface is described. The structures were characterized with X-ray photoelectron spectroscopy (XPS) and corroborated with X-ray diffraction and scanning electron microscopy. Silver nitrate and zinc acetate dihydrate were used as soluble raw materials. Hexamethylenetetraamine was used as the precipitating and reducing agent. The surface of a-cellulose was always treated by hydrogen peroxide before synthesis with a relatively mild effect manifested in water contact angle measurement and XPS high-resolution spectra. The Ag/ZnO decoration system was identified as a true nanodispersed metal/semiconductor hybrid with a unique collective plasmonic structure observed on Ag 3d core lines for the first time. A series of experiments with a single precursor solution contributed to the characterization of the interaction of Ag ? and Zn 2? species with the surface and to the description of the reaction mechanism in the mixed precursor solution. In contrast to previous reports, a specific interaction between the cellulose substrate and Zn 2? was observed. No specific non-thermal effects of microwave heating were observed.

“…Until now, much progress has been achieved in the synthesis of bimetallic NPs with different components and morphologies, which provides us with a wide range of starting materials to yield corresponding metalmodified semiconductor NPs. 40 The synthesis methodology proposed in this paper defines a new way to obtain metal-semiconductor hetero-structures with a perfect crystalline nature. Furthermore, the results from the electrochemical property experiments on the as-prepared noble metal-modified Ni 12 P 5 NPs indicate that the core/ shell Au/Ni 12 P 5 NPs exhibit the best supercapacitor properties, with a specific capacitance of up to 806.1 F g À1 that can be maintained at 91.1% after 500 charge-discharge cycles.…”

A synthetic route to achieve core/shell nanostructures consisting of noble metal cores and single crystal semiconductor shells with different crystal systems is proposed, which involves a simple phosphorization process from corresponding bimetallic heterostructures. The triphenylphosphine is designed to serve as both a capping agent and a phosphorous source during the formation of Au/Ni 12 P 5 core/shell nanoparticles (NPs) from Au-Ni bimetallic heterodimers. The semiconductor shells of the obtained Au/Ni 12 P 5 nanostructures are controlled to form single crystals with a thickness of B5 nm. The structure-dependent supercapacitor properties of Au-modified Ni 12 P 5 nanostructures were further investigated. The synergistic effect of the metal/semiconductor nanostructure is observed to be superior to its oligomer-like counterpart when serving as a supercapacitor electrode. The specific capacitance of an electrode fabricated from core/shell NPs is 806.1 F g À1 with a retention of 91.1% after 500 charge-discharge cycles.
