Photoassisted CO₂ Conversion to Carbon by Reduced NiFe₂O₄

Abstract:

NiFe₂O₄ prepared by a coprecipitation method was reduced by NH₃ to form appropriate amounts of oxygen deficiency, and then the resulting ferrite samples were subjected to the CO₂ flow at 80°C under UV light irradiation. The experimental results showed that the decomposition of carbon dioxide did not take place in dark, but CO₂ could convert to carbon under photo-assistance at 80°C. TEM results suggested that CO₂ decomposed to various forms of carbon, including carbon nanotubes, carbon microspheres, etc. Further, ferrites reduction time is a very important factor for influence the conversion of CO₂.
