Heterostructured CoTe2/g-C3N4 nanocomposite thin film counters electrodes for enhancing the photovoltaic performance of dye-sensitized solar cells

Electronically modulated bimetallic telluride nanodendrites atop 2D nanosheets using a vanadium dopant enabling a bifunctional electrocatalyst for overall water splitting

“…53,54 Furthermore, the Raman signals at 740 cm −1 and 1102 cm −1 are attributed to crystalline CoTe 2 . 55,56 Notably, each Raman mode of V-CoTe 2 /MoTe 2 @CC acquires a slightly higher value compared to CoTe 2 /MoTe 2 @CC, indicating that the V-dopant changes the surface structure of the material. The FTIR spectra of CoMoOH@CC, V-CoMoOH@CC, CoTe 2 /MoTe 2 @CC, and V-CoTe 2 /MoTe 2 @CC are compared in Fig.…”

Emerging 2D Cobalt Telluride (CoxTey): from Theory to Applications

“…[14] The Co x Te y may also grow separately or simultaneously with target supporters or other functional materials to synthesize heterostructured composite materials. [50,51,52] Next, detailed operando procedures and relative merits of every prevalent synthesis routines will be overviewed, intersected with representative characterizations.…”

“…[55] In typical procedures, a diverse family of Co x Te y in forms of nanodots, nanoflakes nanotubes and nanorods could be rationally synthesized. [36,56,57] In addition, mixed-dimensional microstructures (nanoparticles, nanobelts and nanodisks mixture of CoTe) [18,58] and components (CoTe 2 @MoS 2 , CoTe 2 @g-C 3 N 4 ) [48,52] with controlled morphology could also be one-pot synthesized by optimizing the reaction time, reaction temperature and adopted surfactants.…”
