Synthesis and characterization of Ho-doped SmFeO3 nanofibers with enhanced glycol sensing properties

Preparation of C/Ho co-doped TiO2 for enhancing the photocatalytic degradation efficiency of tetracycline hydrochloride

“…As shown, the crystallite size decreases with the increase in Ho doping. Shi et al 29 and Han et al 31 obtained similar results, and this observation can be related to the fact that the dopant Ho replaces Ti and forms Ti-O-Ho bonds in the lattice, thus inhibiting crystallite growth. 32 In addition, the degree of lattice distortion increased with an increase in Ho doping and this results in the positive and negative charge centers of the TiO 6 octahedron which no longer coincide, thus producing an internal dipole moment.…”

“…18,45 Fig. 3(e) shows the Ho 4d XPS spectrum containing a low-intensity peak at 159.4 eV, consistent with Ho-Ho bonds, and a peak at a binding energy 161.8 eV, consistent with Ho-O bonds, 31,40,46 indicating that Ho was doped into the lattice by replacing Ti.…”

Preparation, characterization and magnetic properties of Sm0.95Ho0.05FeO3 nanoparticles and their application in the purification of water

“…The XPS peak of Ho 4d at a binding energy of 160.79 eV due to the presence of Ho 3+ is shown in Fig. 5b [39][40][41]. The Ho 4d spectrum is obvious in a small range of scan spectra as a result of the very small quantity of Ho in Sm 0.95 Ho 0.05 FeO 3 perovskite.…”

“…16). 91 Similarly, doping Nd at the A-site of LaFeO 3 , i.e. La 1− x Nd x FeO 3 , would be beneficial for getting a superior ultra-sensitive response to ethanol in comparison to LaFeO 3 , LaFe 1− x Mg x O 3 , LaFe 1− x Mg x O 3 counterparts which are known for ethanol sensing.…”
