Metal-decorated single-walled carbon Nanotubes for hydrogen storage at ambient conditions

Cel

The primary objectives of the proposed project are to explore innovative idea of application of metal decorated carbon single-walled nanotubes (SWNTs) for vehicle onboard hydrogen storage with the capacity reaching or exceeding 5 wt.% at ambient conditions, to develop scientific bases of the rational design of metal decorated carbon SWNTs on microfiber support and to arrive at a fundamental understanding of their structure - hydrogen adsorption performance relationships. The technical goal of the project is to demonstrate under realistic semi-technical conditions applicability of the developed sorbents for vehicle onboard hydrogen storage at ambient conditions to follow Directive 2003/30/EC. The economic and social goals of the proposed project are in providing new technological knowledge on the preparation and performance of a new class of reversible hydrogen storage adsorbents which will ensure a step forward in the development of novel transportation technologies based on application of environmentally friendly hydrogen fuel. The originality of the proposed research and technological methodologies will be in application of Atomic Layer Deposition for decoration of carbon SWNTs with metal species and the development of the hydrogen sorbent in the form of quartz and high-temperature silica glass microfibers which will facilitate fast hydrogen adsorption/desorption performance and multicycle operation. On project successful completion the main deliverables will be: (i) novel nanolayer catalysts of 20-200 nm thickness on microfiber quartz and high-temperature silica glass supports for the synthesis of carbon SWNTs of 1-2 nm diameter and micrometer length; (ii) carbon SWNTs decorated with metal Ti, Sc, V, Fe, Ni, Co, Pt and Pd species by Atomic Layer Deposition of organometallic precursors including transition metal N,N'-dialkyl-2-alkyl-amidinates; (iii) fundamental relationships between the dispersion or localisation of metal species on carbon SWNTs and their H2 adsorption performance; (iv) novel microfiber sorbents based on carbon SWNTs decorated with metal species for hydrogen storage at ambient conditions with H2 storage capacity reaching or exceeding 5 wt.% and fast hydrogen adsorption/desorption performance and multicycle operation; (v) recommendations and most promising directions of further increasing of hydrogen adsorption capacity of the developed microfiber sorbents based on carbon SWNTs decorated with metal species. The proposed project addresses the needs of the European producers of fuel-cell vehicles. The production of the developed hydrogen sorption materials will need minimum scaling-up, their commercialisation strategy can be realised on a licensing scheme. The project consortium is composed of 5 partners from 4 countries (Russia, Spain, The Netherlands and Ukraine) and integrates the experts in nanomaterials science, catalysis, surface chemistry and sorption technology.
