Chemistry of Carbon Nanotubes

When considering new sensory technologies one should look to nature for guidance. Indeed, living organisms have developed the ultimate chemical sensors. Many insects can detect chemical signals with perfect specificity and incredible sensitivity. Mammalian olfaction is based on an array of less discriminating sensors and a memorized response pattern to identify a unique odor. It is important to recognize that the extraordinary sensory performance of biological systems does not originate from a single element. In actuality, their performance is derived from a completely interactive system wherein the receptor is served by analyte delivery and removal mechanisms, selectivity is derived from receptors, and sensitivity is the result of analyte-triggered biochemical cascades. Clearly, optimal artificial sensory sys-

Due to the complexity of the synthetic process of cobalt phosphides (CoP), ongoing efforts concentrate on simplifying the preparation process of CoP. In this work, amino tris(methylene phosphonic acid) (ATMP, L1) and melamine (MA, L2) are assembled into two-dimensional (2D) organic nanostructures by hydrogen bonding and ionic interactions via a supramolecular assembly, which greatly weakens the coordination ability of L1 with Co2+. As the introduced L2 is rich in carbon and nitrogen, it allows the cobalt-organophosphate complex to be placed under a strongly reducing atmosphere during the high-temperature calcination process to achieve an in situ phosphating purpose. The resulting catalyst (N-CoP/NC) exhibits the sought-after enhanced oxygen reduction reaction (ORR) and hydrogen evolution reaction (HER) performance. For the ORR in 0.1 M KOH, an enhanced onset potential (0.908 V vs. RHE) and diffusion limiting current (6.280 mA cm-2) can be obtained, which is comparable to those of 20% Pt/C (0.911 V vs. RHE, 5.380 mA cm-2). For the HER in 0.5 M H2SO4, an overpotential of 150 mV is required to drive a current of 10 mA cm-2. Moreover, Density Functional Theory (DFT) calculations reveal the catalytic pathway of N-CoP/NC.

Regulating the coordination capacity of ATMP using melamine: facile synthesis of cobalt phosphides as bifunctional electrocatalysts for the ORR and HER.

This book chapter describes the recent advances in the design of novel materials for enzymatic fuel cells. Energy conversion using biologic catalysts became a steady growing research field for supplying nomad or implantable devices due to the high specifity for the substrates and the high efficiency of redox enzymes. The constant issue, however, is the electric connection of the enzymatic redox centre to the electrode to obtain a high efficient biofuel cell. Among many advantages, nanotechnology have been offering exciting tools to achieve efficient interfacing between redox enzymes and electrical circuitry, while providing high active surfaces. We briefly introduce the principles that govern the production of electrical energy from biofuels using a biofuel cell. We focus our discussion on nanomaterials that have realized the efficient immobilization and wiring of enzymes, in particular carbon nanotubes, inorganic and polymer nanoparticles. We highlight the successfull use of these advanced materials in the engineering of enzyme electrodes and the design of novel miniaturized biofuel cell setups.
