Effect of (Nd, Ni) co-doped on the multiferroic and photocatalytic properties of BiFeO 3

Sol-gel synthesis and characterisation of (Nd, Cr) co-doped BiFeO3nanoparticles

“…The mechanism for the degradation of the MB is a photo-Fenton type process [37] and an increase in separation of photo-generated charge carriers with the addition of H 2 O 2 , as H 2 O 2 acts as a scavenger of electrons. The possible photo-Fenton process under visible light is as follows [39,40]:…”

Perovskite Oxide Catalysts for Advanced Oxidation Reactions

“…Vanga and co‐workers also proved that Nd and Ni co‐doping could reduce E bg and show better performance due to the alternation of lattice parameters of BiFeO 3 by hetero‐doping. [ 122 ]…”

Impact of (Zr, Cu) Ion Substitution on the Optical, Dielectric, and Impedance Behavior of BiFeO3

“…It has been demonstrated that co-substitution of Gd and Mn in BFO resulted in reduced bandgap energy [10]. Vanga et al [14,40] have reported decreased bandgap for Ni, Cr and Nd, Ni codoped BFO nanoparticles. Furthermore, Sm and Ni co-doping of BFO also introduced a decrease in bandgap compared with undoped BFO [42].…”

“…[1][2][3][4]. For the past decade, tremendous research has been focused on the improvement of multiferroic properties of BFO by simultaneous substitution of A and B sites by transition/rare earth metal ions [5][6][7][8][9][10][11][12][13][14][15][16][17][18][19][20]. Earlier reports have confirmed that codoping in BFO has resulted in enhancement of dielectric properties and lowering of dielectric loss [15][16][17][18][19][20][21][22].…”

“…Reported values for the optical bandgap of BiFeO 3 at room temperature range from 1.7 to 2.8 eV [10,21,[31][32][33][34][35][36][37][38][39]. According to many authors, BFO is a direct bandgap semiconductor [14,34,35,40], while few others have calculated both the direct and indirect bandgaps [32,33,37,41]. Extensive investigations have been carried out to tune the optical bandgap of BFO ceramic by introducing this co-doping approach.…”
