Photocatalysts active under visible light for photoreforming of waste
Entity:
Design, preparation and characterisation of photocatalytic materials active under visible light for hydrogen production from wastewater. The expected efficiency of new materials based on innovative formulations for hydrogen production and simultaneous water treatment is evaluated by means of tests under simulated sunlight or exclusively with the visible part of the sunlight. Specifically, we investigate the design of photocatalysts based on:
- Doped titanium dioxide
- Carbon nitride
- Copper oxides
- Cerium oxides
- Inorganic copper, iron, cobalt and nickel phosphates
- Perovskites
Challenges met
- Low activity of conventional photocatalysts under visible light.
Scope of application
Photocatalytic technologies for air purification, water decontamination and production of renewable synthetic fuels (hydrogen, methanol, biomethane, etc.). Ideally focused on using sunlight as the main source of activation energy in pollutant removal processes, or as a primary renewable energy source.
