Laser effects on phase transition for cubic Sb₂O₃ microcrystals under high pressure

Abstract

Laser irradiation transforms Sb2O3 from the tetragonal phase into an HD-amorphous phase under high pressure and back to cubic phase from LD-amorphous phase at ambient conditions.

Fullerene as a Photoelectron Transfer Promoter Enabling Stable TiO2‐Protected Sb2Se3 Photocathodes for Photo‐Electrochemical Water Splitting

“…Moreover, as shown in Figure S9a (Supporting Information), this broad feature was first observed from PTS_3.5h, indicating that the surface decomposition of Sb 2 Se 3 accompanies the p–n junction destruction in the exponentially decreasing region (i.e., 3–5 h of PEC operation). In addition, Figure S9b (Supporting Information) shows a minor broad band at 300–450 cm −1 corresponding to an amorphous phase of Sb 2 O 3 , which can be formed along with the surface decomposition of Sb 2 Se 3 (Equation ). It should be noted that both broad features in 240–280 and 300–450 cm −1 regions represent the decomposed products of Sb 2 Se 3 surface.…”

However, the characteristic diffraction peaks of the orthorhombic Sb 2 O 3 and cubic Sb 2 O 3 (JCPDS No.…”

“…For example, the diffraction peaks located at 2θ=26.4°, 42.0°, 48.2°, 49.0°, 59.1°, 62.2°, 67.1°, 68.9° are attributed to (311), (511), (531), (442), (551), (642), (800), (733) facets of the cubic Sb 2 O 3 (JCPDS card No. 43–1071),,, respectively. It indicates that the solvent plays an important role in determining the crystallite phase of Sb 2 O 3 in the solvothermal synthesis process.…”

“…It can be clearly seen that all the diffraction peaks of the Sb 2 O 3 sample (a) (prepared in water) and (c) (synthesized in ethanol) are ascribed to orthorhombic Sb 2 O 3 (JCPDS card No. 11–0689) ,,. The diffraction peaks at 2θ=19.4°, 25.5°, 28.4°, 32.7°, 33.0°, 33.8°, 36.6°, 37.9°, 39.7°, 40.9°, 42.9°, 44.2°, 46.0°, 47.1°, 48.1°, 49.6°, 50.5°, 54.8°, 56.6°, 57.5°, 58.7°, 60.8°, 62.3°, 63.2°, 65.9°, 66.7°, 65.9°, 68.5° are assigned to (110), (111), (121), (131), (002), (012), (200), (141), (032), (211), (221), (042), (231), (240), (142), (052), (161), (170), (310), (171), (242), (261), (072), (252), (223), (341), (223), (350) planes of the orthorhombic Sb 2 O 3 (JCPDS card No.…”

The State and Challenges of Anode Materials Based on Conversion Reactions for Sodium Storage

“…Apart from the transition metal oxides, main group metal oxides such as SnO x , SnO, SnO 2 , Sb 2 O 4 , and Sb 2 O 3 were investigated as anodes in SIBs. Analogous to transition metals, these tin oxides also deliver low reversible capacities that are much less than the corresponding theoretical capacities, even if the electrodes were optimized by nanostructure engineering .…”
