Effect of Gd and Y co-doping in BiVO4 photocatalyst for enhanced degradation of methylene blue dye

RuS2@CN-x with exposed (200) facet as a high-performance photocatalyst for selective C–C bond cleavage of biomass coupling with H–O bond cleavage of water to co-produce chemicals and H2

“…Afterwards, the h + reacted with H 2 O to produce ˙OH and protons. 80 Meanwhile, with electrons reacting with protons to generate hydrogen, resulting in a reduction half-reaction, RuS 2 nanoparticles anchored on the CN surface to receive protons as reduction sites.…”

Combined experimental and DFT approach to BiNbO4polymorphs

“…The UV-Vis absorption spectra were used to determine the photocatalytic efficiency of our samples in deteriorating the MB dye exposed under solar radiation simulated by a Hg–Xe lamp. 84 We prepared 100 mL solution containing 50 ppm MB. For both α-BNO and β-BNO polymorphs, the sample densities were taken to be 1 g L −1 with a solution pH value of 4.5.…”

Chabazite Synthesis and Its Exchange with Ti, Zn, Cu, Ag and Au for Efficient Photocatalytic Degradation of Methylene Blue Dye

“…χ is the absolute electronegativity calculated from the geometric mean of the absolute electronegativity of the constituent atoms of the semiconductor material. E C is the free electron energy on the hydrogen scale (4.5 eV) and E g is the optical band gap of the material [69,70]. The VBM and CBM potentials versus normal hydrogen electrode (NHE) of the samples are listed in Table 3.…”
