چکیده
Oxygen vacancies-enriched black TiO2 is one promising support for enhancing hydrogen evolution reaction (HER). Herein, oxygen vacancies enriched supported sub-nanometer Pt clusters (Pt/TiO2-OV) with metal interactions designed through solvent-free microwave and following low-temperature electroless approach the first time. High-temperature strong reductants are not required then can avoid aggregation of decorated species. Experimental theoretical calculation verify that created exhibit synergistic effects optimizing kinetics. Based on it, Pt/TiO2-OV presents remarkable electrocatalytic performance 18 mV to achieve 10 mA cm−2 coupled small Tafel slope 12 dec−1. This work provides quick synthetic strategy preparing titanium dioxide based nanomaterials.

In this study ternary Ni-P-CeO2 catalysts were first synthesized by the Co-electrodeposition method on a copper substrate and then characterized by means of microstructural and electrochemical techniques toward a hydrogen evolution reaction (HER). Also, for comparison other catalysts such as Ni-CeO2, Ni-P, and Ni were prepared and characterized by the same methods. The microstructure of the inv...
متن کاملPhase-controllable synthesis of cobalt hydroxide for electrocatalytic oxygen evolution.
Identification of active sites for oxygen evolution reaction (OER) plays a key role in the design and fabrication of high-performance cobalt-based electrocatalysts. Herein, we report the synthesis of two types of two-dimensional monometallic cobalt hydroxide nanoplates in aqueous solution for OER: α-Co(OH)2 with both Co2+Td and Co2+Oh sites and β-Co(OH)2 with Co2+Oh sites. Electrochemical chara...
متن کاملElectronic Structures of Clusters of Hydrogen Vacancies on Graphene
Hydrogen vacancies in graphane are products of incomplete hydrogenation of graphene. The missing H atoms can alter the electronic structure of graphane and therefore tune the electronic, magnetic, and optical properties of the composite. We systematically studied a variety of well-separated clusters of hydrogen vacancies in graphane, including the geometrical shapes of triangles, parallelograms...
متن کاملOxygen vacancies as active sites for water dissociation on rutile TiO(2)(110).
Through an interplay between scanning tunneling microscopy experiments and density functional theory calculations, we determine unambiguously the active surface site responsible for the dissociation of water molecules adsorbed on rutile TiO(2)(110). Oxygen vacancies in the surface layer are shown to dissociate H(2)O through the transfer of one proton to a nearby oxygen atom, forming two hydroxy...
