Synthesis and Investigation of Thermodynamic Properties of Cu5V2O10

Elucidating the optical, electronic, and photoelectrochemical properties of p-type copper vanadate (p-Cu5V2O10) photocathodes

“…† The Cu 5 V 2 O 10 phase has been previously found to crystallize in the monoclinic crystal system (space group P2 1 /c) with the cell parameters of a ¼ 8.3938Å, b ¼ 6.0659 A, c ¼ 16.1601Å and b ¼ 108.0857 . 15,[21][22][23] Fig. 1b shows the Raman spectra of our sprayed Cu 5 V 2 O 10 samples with different thicknesses.…”

Nanoscale Heterogeneities and Composition–Reactivity Relationships in Copper Vanadate Photoanodes

“…For nominally stoichiometric Cu 5 V 2 O 10 grown on SiN x , GIXRD results are consistent with the stoiberite phase, with no indications for secondary phase formation (Figure 1a). 22 By contrast, the Cu-deficient sample shows additional diffraction peaks at 14.4, 24.9, and 33.4°, indicating the presence of a minority phase of Cu 11 V 6 O 26 (Figure 1b). 6 Therefore, we assign the Cu-deficient sample as a mixed-phase of Cu 5 V 2 O 10 and Cu 11 V 6 O 26 .…”

Thermal properties of matter within the model of a two-phase system

“…Entropy of a locally equilibrium region. Let us set a density of system's substantive entropy at a changing phase composition x = x 1 using a ratio (taken with the minus sign) of the differential of function (5)…”

“…Table 1 gives the model parameters for complex oxides discussed in [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. As an example, Fig.…”

“…Experimenters are currently showing a constant interest in studying the heat capacities of complex oxides [1][2][3][4][5][6][7][8][9][10][11][12][13][14]. It is due not only to their technical use (e.g., ceramics [15]), but also the uniqueness and diversity of physical properties.…”
