In contemporary research, “Heterostructure” assemblies play an important role in energy conversion systems, wherein the composite assemblies facilitate faster charge carrier transport across the material interfaces. The improved/enhanced efficiency metrics in these systems (electro/photo-electrochemical processes/devices) is due to synergistic interaction and synchronized charge transport a...

Iron (Fe) and nitrogen (N) were introduced as dopants into zirconium titanate (ZrTiO4) in order to study the codoping effects of on iron-doped (Fe,N-codoped ZrTiO4) composite. Titanium tetraisopropoxide (TTIP), zirconia (ZrO2), urea, iron(II) sulfate heptahydrate used source TiO2, semiconductor supports, nitrogen, iron, respectively. A specific amount iron (1, 3, 5, 7, 9 wt.%) a fixed content (...

The aim of this study was to synthesize N, P codoped CQDs modifying TiO2/g-C3N4 nanorod array (i.e., P-CQD/TCN NA) photoanodes for the degradation 1,4-dioxane (1,4-D) and explore possibility photoelectrocatalytic (PEC) process in wastewater treatment. With characterization NA anodes, 1,4-D pesticide tested PEC cell, respectively. Under a bias voltage 1.2 V visible light, current density NAs muc...

Subsequent stages of atomic-deficient nanostructurization finalizing rare-earth functionality under Pr3+-doping in Ga2(As0.28Sb0.12Se0.60)98 glass are studied employing method of positron annihilation lifetime spectroscopy. Genesis of free-volume positron trapping sites, composed of atomic-accessible geometrical holes (void cores) arrested by surrounding atomic-inaccessible Se-based bond-free s...

Using density functional theory and the Hubbard U method, we investigated the geometric structure, electronic structure, and optical property of Al/Ga-codoped ZnO. A 3 × 3 × 3 ZnO supercell was used to construct Al- and Ga-monodoped ZnO structures and Al/Ga-codoped ZnO (AGZO) structures. All three structures showed n-type conduction, and the optical band gaps were larger than that of pure ZnO. ...
