In this work, iron oxide based catalysts doped with Al and Mn in HTS reaction were investigated. The catalysts were prepared by co-precipitation from metals nitrate solutions, using ammonium hydroxide (25% w/v) as precip...

This chapter presents different phenomena that arise when nanomaterials reach the environment, with emphasis in water systems. Transformations on the surface of nanomaterials and nanoparticles because of adsorption of ma...

The degradation of chemicals present in wastes by heterogeneous photocatalysis is an important issue and its study is a constantly growing field. An increasing number of papers deal with TiO2 (titania) as one of the most...
