Abstract
The NdVO4- V2O5 powders were synthesized by neodymium nitrate and ammonium metavanadate using the glycothermal method in ethylene glycol at 120°C for 1h.When NdVO4-V2O5 hybrid powdersasbore light that generate electron and hole than charge spearation and migration to the surface of NdVO4-V2O5 hybrid powders, which of the valence band are below the water oxidation potential (1.23 V versus NHE at pH 0). The resutls indicated that the holes of NdVO4-V2O5 hybrid powders can oxidize water molecules to form oxygen as shown in Fig. 1. However, the conduction of hybrid powders was perhaps lower the water reduction potential 0V that casued electron of hybrid powdescan not reduce H+ to form hydrgen in water or sacrificial agent solution (10% methanol).Based on the stoichiometry of NdVO4, the oxidation states and atomic orbitals are given by Nd3+(6s24f4), V5+(3d0), and O2‒ (2p6). The valence band is formed by coupling Nd6s and O 2p orbitals while the conduction band is primarily controlled by V 3d orbitals, with contributions from the O 2p and Nd4f orbitals.
Biography

Deanna Mulvihill has her expertise in evaluation and passion in improving the health and wellbeing. Her open and contextual evaluation model based on responsive constructivistscreatesnewpathwaysforimprovinghealthcare.Shehasbuiltthismodelafteryearsofexperienceinresearch,evaluation,teachingandadministration both in hospital and education institutions. The foundation is based on fourth generation evaluation (Guba& Lincoln, 1989) which is a methodology that utilizes the previous generations of evaluation: measurement, description and judgment. It allows for value-pluralism. This approach is responsive to all stakeholders and has a different way offocusing.
