Construction of a Z-scheme MoS2/CaTiO3 heterostructure by the morphology-controlled strategy towards enhancing photocatalytic activity

Vanadium doped CaTiO3 cuboids: role of vanadium in improving the photocatalytic activity

“…These binding energy values confirmed the existence of +4 oxidation state for Ti in the 1.0 V sample (Figure 4b). 50,51 Further, it is observed that the shift in the peaks for Ca 2p3/2 (346.2 eV in CaTiO3) and 2p1/2 (349.9 eV in CaTiO3) is less compared to Ti 2p3/2 (458.1 eV in CaTiO3)…”

“…and Ca 2p1/2 spin states of Ca 2+ , respectively in 1.0 V (Figure 4a). 50 The peaks at binding energies 458.8 eV and 464.6 eV could be allotted to Ti 2p3/2 and Ti 2p1/2 states, respectively.…”

“…Comparison of the photocatalytic activity of 1.0 V with the previously reported ones show that our material is highly efficient (Table S1). 24,25,30,32,35,50,51,[61][62][63][64][65] where, Co is the initial concentration of dye, C is the concentration of the dye at irradiation time 't' and 'k' is the first order rate constant. 'k' is calculated from the slope of the linear fit of -ln(C/Co) versus 't'.…”

MoS2-based nanocomposites: synthesis, structure, and applications in water remediation and energy storage: a review

“…Recently, (Jiang et al 2020) have reported the synthesis of MoS 2 /CaTiO 3 heterogeneous for degrading tetracycline in water. The MoS 2 /CaTiO 3 shows a higher photocatalytic achievement toward tetracycline than to pure MoS 2 and CaTiO 3 .…”

Synthesis of novel α-Fe2O3-Bi2S3-Gr for efficient photocatalytic degradation of environmental pollutants under visible-LED light irradiation

“…Many binary heterojunctions have been tested to overcome these issues, such as α-Fe 2 O 3 -WO3, BiVO 4 -Bi 2 S 3 , α-Fe 2 O 3 -BiOI, α-Fe 2 O 3 -Bi 2 S 3 , Bi 2 S 3 -ZnO and etc. [15,16,20,21,[23][24][25][26][27][28][29][30][31]. Meanwhile, many works showed an improvement of performance in organic contaminant degradation by incorporation of a carbonaceous material into photocatalysts with, both singular or binary metal oxides such as α-Fe 2 O 3 -graphene, Bi 2 S 3 -AC, α-Fe 2 O 3 -CNTs; Bi 2 S 3 -Gr, α-Fe 2 O 3 -WO 3 -graphene, α-Fe 2 O 3 -ZnO-graphene and etc.…”
