Synthesis of iron-doped TiO2 nanoparticles by ball-milling process : the influe...

Carneiro, Joaquim A. O.; Azevedo, Sofia; Fernandes, Filipa Daniela Pereira; Freitas, Elisabete F.; Pereira, Mário R.; Tavares, C. J.

Titanium dioxide (TiO2) absorbs only a small fraction of incoming sunlight in the visible region thus limiting its photocatalytic efficiency and concomitant photocatalytic ability. The large-scale application of TiO2 nanoparticles has been limited due to the need of using an ultraviolet excitation source to achieve high photocatalytic activity. The inclusion of foreign chemical elements in the TiO2 lattice can ...

Carneiro, Joaquim A. O.; Samantilleke, A. P.; Parpot, Pier; Fernandes, F.; Pastor, M.; Correia, A.; Luís, E. A.; Barros, A. A. Chivanga; Teixeira, V.

In recent years, new textile materials have been developed through the use of nanotechnology-based tools. The development of textile surfaces with self-cleaning properties has a large combined potential to reduce the environmental impact related to pollution. In this research work, three types of textiles substrates (cotton, Entretela, and polylactic acid (PLA)) were functionalized with titanium dioxide nanopar...

Assessment of photocatalytic, superhydrophobic and self-cleaning properties on ...

Rocha Segundo, I.; Ferreira, Cristiano; Freitas, E. F.; Carneiro, Joaquim A. O.; Fernandes, Filipa; Landi, S.; Costa, Manuel F. M.

Photocatalytic, superhydrophobic and self-cleaning capabilities were promoted on AC 6 and AC 14 asphalt mixtures by spraying of TiO2 and/or ZnO. Initially, physicochemical and morphological properties of bitumen samples were evaluated by Fourier Transform Infrared Spectroscopy and Atomic Force Microscopy after the solution spraying of TiO2, ZnO and TiO2 ZnO. Then, to assure those capacities, Water Angle Contact...

Photocatalytic asphalt pavement: the physicochemical and rheological impact of ...

Rocha Segundo, Iran Gomes da; Dias, Elisa Alexandra Lages; Fernandes, Filipa Daniela Pereira; Freitas, E. F.; Costa, Manuel F. M.

A cost-effective solution to provide asphalt pavements with the photocatalytic property was addressed for the first time, based on the combination of low percentages of two semiconductors, TiO2and ZnO. Two photocatalytic techniques – spray deposition and bitumen modification – were used. With the former, the chemical properties were evaluated by FTIR after spraying the bitumen samples with two aqueous solutions...

Smart, photocatalytic and self-cleaning asphalt mixtures: a literature review

Rocha Segundo, Iran; Freitas, E. F.; Landi, Salmon; Costa, Manuel F. M.; Carneiro, Joaquim O.

Nowadays, there is increasing concern in transportation engineering about the use of techniques less harmful to the environment and also about road safety. Heterogeneous photocatalysis based on the application of semiconductor materials onto asphalt mixtures is a promising technology because it can mitigate air pollution and road accidents. The functionalized asphalt mixtures with photocatalytic capability can ...
