The neutral hydrogen evolution reaction (HER) is vital in the chemical industry, and its efficiency depends on interior character of catalyst. Herein, work function ( W F ) engineering introduced via 3 d metal (Fe, Co, Ni, Cu) doping for modulating Fermi energy level Mo 2 C. defective facilitates free water molecule adsorption and, subsequently, promotes HER efficiency. Specifically, at a curre...

Bismuth vanadate (BiVO4), W-doped BiVO4 (BiVO4:W), and Mo-doped (BiVO4:Mo) nanoparticles were synthesized at pH = 4 using a green hydrothermal method. The effects of 2 at% W or Mo doping on the microstructural optical characteristics as-prepared effect combining particle morphology modification impurity dopant incorporation visible-light-derived photocatalytic degradation dilute Rhodamine B (Rh...

Naphthalene hydrogenation was studied over a novel Ni–Al-layered double hydroxide-derived Mo-doped mixed metal oxide (Mo-MMO), contrasted against bifunctional NiMo/Al2O3, and Pd-doped Al2O3 catalysts, the latter of which with Pd loadings 1, 2, 5 wt %. Reaction rate constants were derived from pseudo-first-order kinetic pathway describing two-step to tetralin (k1) decalin (k2). The Mo-MMO cataly...

Abstract The most popular semiconductor in dye-sensitized solar cells (DSSCs) is titanium dioxide (TiO 2 ) because of its low cost, non-toxicity, and good stability. However, the DSSCs still have efficiency due to light absorption TiO visible region. Understanding properties can contribute improving DSSCs. In this study, we use density functional theory investigate electronic optical brookite (...

In the unconventional superconductor Sr2RuO4, substitution of a small amount of Mo for Ru destroys the superconducting state. We have used low energy electron diffraction (LEED) and scanning tunneling microscopy (STM) to study the cleaved (1 0 0) surface of the Mo-doped strontium ruthenate: Sr2Ru0:9Mo0:1O4. Excellent LEED patterns indicate a well-ordered surface similar to Sr2RuO4. The analysis...

Transition metal dichalcogenides (TMDCs) have recently been the focus of extensive research activity owing to their fascinating physical properties. As a new member of TMDCs, Mo doped ReSe2 (Mo:ReSe2) is an octahedral structure semiconductor being optically biaxial and highly anisotropic, different from most of hexagonal layered TMDCs with optically uniaxial and relatively high crystal symmetry...

Enhancement of upconversion luminescence is imperative for the applications of upconversion nanocrystals (UCNs). In this work, we investigated the upconversion luminescence enhancement of NaYF4:Yb/Er by Mo(3+) ion doping. It was found that the upconversion luminescence intensities of the green and red emissions of UCNs co-doped with 10 mol% Mo(3+) ions were enhanced by 6 and 8 times, respective...

The present investigation highlights the synthesis of polyaniline (PANI)-coated graphene oxide doped with SrTiO3 nanocube nanocomposites through facile in situ oxidative polymerization method for the efficient removal of carcinogenic dyes, namely, the cationic dye methylene blue (MB) and the anionic dye methyl orange (MO). The presence of oxygenated functional groups comprised of hydroxyl and e...

Transition metal doping into the TiO2 lattice can expand the response of these metal oxide nano particles to the visible region. In view of this, Mo ion is doped into the TiO2 lattice in order to understand the mechanism of its photo response. The prepared photocatalysts were characterized by X-ray diffraction, UV–Visible absorption spectroscopy, UV–Visible diffuse reflectance spectroscopy, SEM...
