2019, Journal of the European Ceramic SocietyCitation Excerpt :In this context, cork emerges as an outstanding natural template for the production of 3DOM CeO2 due to its regular 3DOM structure, consisting of hollow hexagonal honeycomb cells [23]. Up to now there have been very few investigations into CeO2 ecoceramics [16,33]. In 2008, Matovic et al. [33] reported the production of porous Ce1-xGdxO2-δ using Linden (Tilia amurensis) wood as a template.
Solar energy and cork: A binomial of the future?
2018, Science and Technology of MaterialsCitation Excerpt :However, the rear hexagonal walls are pierced (this feature does not occur in cork) and so, gases like hydrogen can permeate well into the structure. With this, the reactive surface available for catalysis is increased [19]. Based on this, a first set of experiments for hydrogen production using a thermochemical process in cycling studies with an experimental concentrated solar device showed a peak of hydrogen release of 0.14 ml H2/g min (8.4 l/kg h).
Solar thermochemical CO<inf>2</inf> splitting using cork-templated ceria ecoceramics
2018, Journal of CO2 UtilizationCitation Excerpt :Two ceria-based materials synthesised at both the University of Aveiro and LNEG were investigated in the form of granules and foams. For this purpose, cork-template based-ceria granules (hereafter denoted as CG) were synthesised following a procedure described elsewhere [42], in which cork granules (typically of a size of several millimetres) were heat treated in a nitrogen atmosphere at 900 °C for 30 min to form carbon templates. These were then infiltrated with cerium nitrate solution (Ce(NO3)3·6H2O, 99%, Sigma Aldrich), dried overnight, and heated in air to 1600 °C for 30 min to remove the carbon, leaving a pure ceria ceramic while preserving the 3-DOM structure of cork.
