Highly Active Photocatalyst of Cu2O/TiO2 Octahedron for Hydrogen Generation

Preparation of highly visible-light active N-doped TiO2 photocatalyst†

A series of N-doped anatase TiO2 samples have been prepared using a solvothermal method in an organic amine/ethanol–water reaction system. The effects of different starting N : Ti atomic ratios on the catalysts structure, surface property and catalytic activity have been investigated. The photocatalytic activity and stability of the N-doped TiO2 samples were evaluated through using the decompos...

Ultrastable Polymolybdate-Based Metal-Organic Frameworks as Highly Active Electrocatalysts for Hydrogen Generation from Water.

Two novel polyoxometalate (POM)-based metal-organic frameworks (MOFs), [TBA]3[ε-PMo(V)8Mo(VI)4O36(OH)4Zn4][BTB]4/3·xGuest (NENU-500, BTB = benzene tribenzoate, TBA(+) = tetrabutylammonium ion) and [TBA]3[ε-PMo(V)8Mo(VI)4O37(OH)3Zn4][BPT] (NENU-501, BPT = [1,1'-biphenyl]-3,4',5-tricarboxylate), were isolated. In these compounds, the POM fragments serving as nodes were directly connected with org...

Nanoporous nickel spheres as highly active catalyst for hydrogen generation from ammonia borane.

Development of Visible-light-active Photocatalyst for Hydrogen Production and Environmental Application

Semiconductor photocatalysis has been intensively studied in recent decades for a wide variety of application such as hydrogen production from water splitting and water and air treatment. The majority of photocatalysts are, however, wide band-gap semiconductors which are active only under UV irradiation. In order to effectively utilize visible solar radiation, this thesis investigates various t...

A novel amorphous CoSnxOy decorated graphene nanohybrid photocatalyst for highly efficient photocatalytic hydrogen evolution.

A novel amorphous cobalt tin composite oxide decorated with graphene nanohybrid (CoSnxOy/G) sensitized by Eosin Y (EY) exhibited excellent photocatalytic hydrogen evolution activity (974.6 μmol for 3 h) under visible light irradiation. The highest AQE of EY-CoSnxOy/G of 20.1% was achieved at 430 nm.
