Impregnation treatments are one of the alternatives to protect concrete-based building and monuments from weathering degradation. However, it is important consider chemical compatibility reaction products with material. The impregnation product studied here consists a silica oligomer able polymerize, by simple sol-gel process, inside pore structure concrete. In this work, we investigate ability treatment produce C-S-H gel in contact cement paste. A complete characterization demonstrated that...

High-resolution electron microscopy (HREM), combined with digital image processing and computer simulation techniques, has been used to carry out a microstructural characterization of some Rh/TiO2 catalysts reduced at 473, 773 or 823 K. A sample resulting from the reduction catalyst K, reoxidized flowing O2 673 K finally 473 was also investigated. In contrast earlier literature reports, HREM images recorded here suggest existence definite structural relationships between both rutile anatase...
On the basis of detailed previous knowledge about correlation existing between Oxygen Storage Capacity (OSC) ceria–zirconia mixed oxides, nature redox pretreatments and nanostructure this family complex materials, it has been possible to design a synthetic strategy allowing one prepare ceria–yttria-doped zirconia with total ceria contents below 20%, featuring OSC values higher than those observed for catalysts which incorporate supported noble metal particles in their formulation, especially...

The redox behaviour of a Ce0.68Zr0.32O2 mixed oxide is reversibly modified by alternating high temperature (1223 K) reduction with either mild (823 or re-oxidation treatments.
A new method to compare the oxygen buffering capacity (OBC) of catalysts shows that Ce–Tb mixed oxide presents an exceptional capability for attenuating fast oscillations partial pressure.
