, Physico-chemical properties and possible photocatalytic applications of titanate nanotubes synthesized via hydrothermal method, Journal of Physics and Chemistry of Solids, doi:10.1016Solids, doi:10. /j.jpcs.2009 This is a PDF file of an unedited manuscript that has been accepted for publication. As a service to our customers we are providing this early version of the manuscript. The manuscript will undergo copyediting, typesetting, and review of the resulting galley proof before it is published in its final citable form. Please note that during the production process errors may be discovered which could affect the content, and all legal disclaimers that apply to the journal pertain. of TNTs synthesized at 140°C was about 2.5 times higher than that generated with use of TiO 2 P25. To the best of our knowledge this is a first report on the photocatalytic generation of hydrocarbons using TNTs in the current state of the art.

Porous carbon materials were prepared by heating of a PET [poly(ethylene terephtalate)] and magnesium carbonate (3MgCO 3 • Mg(OH) 2 • 3H 2 O) mixture under Ar gas flow, followed by acid washing. The inorganic component of the mixture underwent thermal decomposition with formation of MgO and evolution of gaseous products including CO 2 and H 2 O. Influence of the magnesium compound mixed with PET, and carbonization temperature on the pore structure of carbonaceous material is presented. As found, porosity of prepared materials depended on magnesium carbonate loading in the starting mixture and on heating temperature. The impact of CO 2 and H 2 O evolved during heating on the pore structure is discussed, and a mechanism of pore formation is proposed.
