The Gadolinium (Gd³⁺) and Tin (Sn⁴⁺) Co-doped BiFeO₃ Nanoparticles as New Solar Light Active Photocatalyst.

ABSTRACT: The process of photocatalysis is appealing to huge interest motivated by the great promise of addressing current energy and environmental issues through converting solar light directly into chemical energy. However, an efficient solar energy harvesting for photocatalysis remains a critical challenge. Here, we reported a new full solar spectrum driven photocatalyst by co-doping of Gd³⁺ and Sn⁴⁺ into A and B-sites of BiFeO₃ simultaneously. The co-doping of Gd³⁺ and Sn⁴⁺ played a key role in hampering the recombination of electron-hole pairs and shifted the band-gap of BiFeO₃ from 2.10 eV to 2.03 eV. The Brunauer-Emmett-Teller (BET) measurement confirmed that the co-doping of Gd³⁺ and Sn⁴⁺ into BiFeO₃
