A perspective on bismuth based materials for the photodegradation of organic pollutants

Abstract

The photoactive bismuth materials represent an interesting tool for facing the complexity represented by the organic contained wastewater streams and the engineering of their chemical and surface properties is the key to a solve the water pollution. In this review, we are discussing the use of bismuth based materials for photooxidative treatment of polluted water critically evaluating and highlighting the strengths and the weaknesses of the approach with a focus on the properties of the materials but reporting as well the currently available technologies providing an agile reference point in the field.
