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

“…3,4,5,6,7,8 While thermoelectric materials help scavenge the waste heat and convert them to electricity without the release of harmful gases, photocatalysis strategy tackles these issues by using sunlight as a green, low cost and renewable resource for generation of hydrogen and degradation the pollutants. 9,10,11,12 Metal oxides and their composites have been utilized in energy and environmental remediation due to their ease of synthesis, excellent stability, photo-corrosion resistance and superior efficiency. 4,[13][14][15] Among the metal oxides, CaTiO3, is the first known perovskite material which has sparked research interest due to the above mentioned promising features for the decomposition of water and degradation of harmful organic pollutants.…”

Nanostructured CdS for efficient photocatalytic H2 evolution: A review

“…cocatalysts to promote the kinetics of photocatalytic H 2 generation. To date, various cocatalysts, such as Au [344,345], Pt [321,346,347], Ag 2 S [348], MXenes [238,[349][350][351][352], CoMoS x [353], MoO x S y [354], MoS 2 [222,[355][356][357][358], Ni 3 C [176], Ni 2 P [359,360], NiS x [63,322,361], NiCoP [362], CoP x [199,363], CuS x [212,246], and WS 2 [364,365] [229] found that a 0.2 molar ratio of NiS improved the average charge carrier lifetime of CdS by 97 times, potentially leading to more efficient charge separation and transfer. They synthesized CdS NWs and NiS with tight connections using a two-pot solvothermal synthesis.…”

Fast photodegradation of antibiotics and dyes by an anionic surfactant-aided CdS/ZnO nanodispersion

“…Fig. 6b shows the Tauc relationship, 46 and the straight line is extrapolated and yields the energy band value, where the band gap energies (Eg) are 3.27 eV and 2.33 eV for ZnO and CdS, respectively. In addition, the E g values of CSZ4 are 3.15 eV and 2.55 eV (Fig.…”
