Formation enthalpy, thermodynamic stability, lattice energy of (Er,Co)-doped Bi 2 O 3

Tuning the potentials of aluminum phosphide nanotube photocatalyst for wastewater treatment through band gap engineering: a DFT study

“…Additionally, cohesive energy decreases with an increase in the concentration of dopant which results in efficient thermal stability [33]. The obtained values of the formation energy indicated that the doped AlPNTs are thermodynamically stable, which is well consistent with previous studies [34]. Claims to that this is connected to the fact that materials with low cohesive energy and higher values of binding energy tend to be more thermodynamically stable [35].…”

Stabilities and performance of single cubic phase dysprosium and zirconium co-doped bismuth oxide electrolytes for low temperature solid oxide fuel cells

“…Meng et al 36 reported that a smaller amount of double-dope oxides can remain in the cubic phase at room temperature compared with that of a single dope oxide. Therefore, the effects of co-dopants such as Y–Ln (Ln = Ce, 37 Er, 38 Gd, 39 Nb, 39 Sc 39 and Zr 39 ), Dy–Ln (Ln = W, 40–42 Gd, 43 Ce, 43 Ho 44 and Ta 45 ), Er–Ln (Ln = W, 46 N 5 47 and Co 48 ), Eu 2 O 3 –Tb 4 O 7 , 49 La 2 O 3 –MoO 3 , 50 Gd 2 O 3 –Lu 2 O 3 , 51 Tb 4 O 7 –Gd 2 O 3 , 52 and Pr 2 O 3 –MoO 3 53 have been extensively studied recently. The co-doping of two metal oxides increases the entropies of quaternary systems, facilitating stabilization of δ-Bi 2 O 3 down to room temperature with lower dopant concentrations.…”
