“…The resistivity of the carbonized samples was calculated using the resistance values measured using a standard digital multimeter (2216-20 TRMS, Milwaukee Electric Tool Corp.; Brookfield, WI) and the procedure previously described [39]. In order to improve the electrical contact with the multimeter connectors, silver paint was applied on the CuNPs-modified pyrolyzed samples by displaying silver contacts with a gap of 1 cm.…”

“…As a modification from a recent publication from our group [39], CuNPs@CEs were obtained by pyrolysis of paper strips (JP40 filter paper, 80 g·m −2 , Quanty; J-Prolab, Brazil) of 1.5 cm × 3.5 cm modified with a solution containing CuSO 4 . The advantages and limitations of this method (rendering bare carbon electrodes) were described in the aforementioned report.…”

A one-step approach for the synthesis and integration of copper nanoparticles (CuNPs) onto paper-based carbon electrodes is herein reported. The method is based on the pyrolysis (1000 °C under a mixture of 95% Ar / 5% H2 for 1 hour) of paper strips modified with a saturated solution of CuSO4 and yields to the formation of abundant CuNPs on the surface of carbonized cellulose fibers. The resulting substrates were characterized by a combination of scanning electron microscopy, EDX, Raman spectroscopy as well as electrical and electrochemical techniques. Their potential application, as working electrodes for nonenzymatic amperometric determination of glucose, was then demonstrated (linear response up to 3 mM and a sensitivity of 460 ± 8 μA·cm−2·mM−1). Besides being a simple and inexpensive process for the development of electrochemically-active substrates, this approach opens new possibilities for the in-situ synthesis of metallic nanoparticles without the traditional requirements of solutions and adjuvants.

“…Heating cellulose paper to high temperatures (1000 C), without the presence of oxygen, creates a dense carbon material. 38 Garcia et al have demonstrated that pyrolyzing paper, under reductive conditions, produces carbonized cellulose fibers. These fibers have been decorated with CuNPs and used as electrodes.…”

“…[13] Alternatively, nanoporous thin films of gold can be prepared by dissolving silver from a film of a silver-gold alloy. [15] Other methods used carbon-based polymeric materials, such as paper and polymeric fibers, as templates for the fabrication of (i) porous, conductive structures of carbon [19] and (ii) porous structures of metal oxides (e.g., TiO 2 , MnO 2 , Fe 2 O 3 ). [20][21][22][23][24] For example, Garcia and co-workers prepared conductive carbon paper by heating paper at 1000 °C in slightly reducing conditions (95% Ar-5% H 2 ).…”

(1 of 8) 1600229wileyonlinelibrary.com metal nanoparticles may have high surface area per unit of weight of metal, but may (depending on the support) be impermeable to gases and liquids.Papers and fabrics have open fibrous structures, which provide them with higher accessible surface area than flat films of similar dimensions, and are permeable to liquids and gases. If noble metals could be fabricated in structures that are morphologically similar to paper or fabric, these structures might exhibit attractive physical properties (e.g., high surface area, mechanical flexibility, permeability to gases and liquids) and might also be plausible materials for use in electroanalysis, as catalysts, electrical conductors, or magnetic collectors.This article describes a method for fabricating free-standing materials of a number of late transition metals (i.e., noble metals); these materials have physical morphologies that resemble paper, thread, or fabric. We call the method "paper-templating," and the resulting structures "paper-templated metals." Paper-templating uses paper or fabric as a template, and solutions of metallic ions deposited on the paper or fabric as precursors to the metal. The template is first loaded with aqueous solutions of salts of noble metals and dried. The paper (or cotton fabric, in same experiments) is then burned off in a stream of air in a furnace held at temperatures between 550 and 800 °C, depending on the procedure, and the resulting structure annealed for 2 min. The method yields structures that resemble the shape and detailed morphology of the original template ( Figure 1A,B); this morphology, at scales down to 2 µm, is remarkably similar to that of the material (e.g., paper) from which they were derived ( Figure 1C-F). The structures are composed primarily (>94% w/w, and 55-80 at%) of elemental metal. Using paper-templating, we fabricated: (i) paper-templated structures of noble metals (i.e., gold, silver, platinum, rhodium, palladium, and iridium), (ii) paper-templated structures of mixtures or alloys of noble metals (i.e., gold-platinum, silverpalladium, gold-rhodium, and gold-rhodium-platinum), and (iii) paper-templated structures with different regions composed of a different noble metal (i.e., gold/silver, platinum/rhodium). These structures were electrically conductive, and permeable to gases and liquids. The surface areas of these structures were more than 20 times higher than their projected areas. The surface of paper-templated gold was electroactive, and the structure could be used as the working electrode for electroanalysis ( Figure 1G,H). Dionysios C. Christodouleas, Felice C. Simeone, Alok Tayi, Sonia Targ, James C. Weaver, Kaushik Jayaram, Maria Teresa Fernández-Abedul, and George M. Whitesides* This manuscript describes a simple and rapid method for fabricating freestanding structures composed primarily (>94% w/w, and 55-80 at%) of noble metals (e.g., gold, silver, platinum, etc.) and having physical morphologies that resemble paper, thread, or fabric. In this method, ...
