The 2015 Spring Conference of the European Materials Research Society (E-MRS)

Ежегодная Международная конференция «The 2015 Spring Conference of the European Materials Research Society (E-MRS, http://www.emrs-strasbourg.com/ ) прошла в городе Лилль, во Франции, в выставочном центре «Гран Пале» с 10 по 15 мая 2015 года.

Конференция посвящена, как фундаментальным аспектам синтеза и исследования свойств наноматериалов (углеродные наноматериалы и нанотрубки, графен, нановолокна, 3D мезо- и микропористые угли для катализа), так и прикладным проблемам их использования (электро- и  фотокатализ, топливные элементы, хранение энергии и др.) в механизмах и устройствах энергетики, а также в технологиях для информатизации и связи.

Особое внимание на Конференции было уделено областям, связанным с разработкой материалов для возобновляемых источников энергии, для защиты окружающей среды, оптики и оптоэлектроники, биотехнологий. Большое количество докладов участников связано с органическими и био-материалами, многофункциональными оксидами для применения в электронике; их синтезом и исследованию их свойств.

В работе Конференции приняли участие около 3000 специалистов в области материаловедения из  50 стран, представившие 3748 докладов.

Организаторы Конференции – Европейское Общество Материаловедения «European Materials Research Society».

На официальном открытии Конференции выступил Президент EMRS Томас Липерт (Thomas Lippert E-MRS President). После приветствия состоялась пленарная сессия  в которой были представлены 3 пленарных доклада авторитетных ученых с мировым именем. Первый пленарный доклад представил  член-корр.

Synthesis of graphite-like carbon nanomaterials (CNMs) is a rapidly growing field of nanotechnology; by now, a large body of knowledge has been accumulated on the subject. In recent years, great efforts were made to find ways to precise control of electrophysical and adsorption properties of CNMs by modification of the carbon structure with heteroatoms, for example with the nitrogen atom (N-CNMs), for the deliberate synthesis of new functional materials.Doping of carbon nanomaterials with nitrogen produces changes in their electrophysical, adsorption and catalytic properties. The catalytic synthesis of nitrogen-doped carbon nanomaterials (N-CNMs) belongs to simple synthesis methods, is performed at moderate temperatures, leads to selective formation of N-CNMs, and is therefore more attractive than the physical synthesis methods.

  A commonly accepted model describing the formation of undoped MWCNTs and CNFs on metal catalysts consists of three main steps: (1) decomposition of hydrocarbon molecules on the catalyst surface with the formation of adsorbed carbon atoms, (2) dissolution of the adsorbed carbon atoms followed by their diffusion within the catalyst particle or over its surface, and (3) formation of a nucleus and growth of a carbon tube or fiber outside the catalyst particle.

  The mechanism of N-CNMs catalytic growth; the understanding of this mechanism is essential in the synthesis of active and stable catalysts for the production of N-CNMs. In situ XRD and ex situ XPS techniques were used to reveal the formation of surface nickel carbide, and oversaturated solid solution in the bulk of the particle. Correlations between composition of the reaction mixture, lattice parameter of solid solution and nitrogen content in N-CNFs were obtained.

  The effect of nitrogen on conductivity of the nitrogen-doped carbon nanomaterials depends on: (1) type of conductivity is inherent in N-CNMs, (2) type of nitrogen species, and (3) total nitrogen content. The defectness of N-CNMs in comparison with CNMs estimated from the Raman spectra and optimal content of nitrogen for maximum conductivity is revealed.

  The introduction of nitrogen atoms induces charges in N-CNMs, because electronegativities of nitrogen and carbon are different and equal to 3.04 and 2.55, respectively. Two main forms of nitrogen content in the quaternary state or pyridine-like nitrogen defines acid – base properties of surface.

  The use of less expensive, environmentally benign and corrosion resistant CNMs is a promising way to replace the metal catalysts. The most interesting lines in the application of N-CNMs for catalysis: oxidation in the gas or liquid phase, dehydrogenation, and various reactions of organic synthesis.

  In recent years, N-CNMs have been studied as the catalyst supports in various reactions. Owing to changes in physicochemical properties, the deposition of metal catalysts on N-CNMs should enhance their activity due to: (1) stabilization of metallic particles with a smaller size, narrowing of the particle size distribution, and increasing the metal-carbon binding energy, (2) acceleration of electron transfer in the catalytic system and activation of metallic particles because of the enhanced conductivity of N-CNMs, and (3) alteration of the acid-base properties of the support surface.

  Changes in physicochemical properties of N-CNMs are accompanied by showing of their own catalytic activity. The beneficial role of nitrogen in provides new applications as the catalyst supports. The results of testing of N-CNMs in a number of catalytic reactions, in PEMFC and in supercapacitors will be presented.
