Controllable synthesis of Au-TiO2 nanodumbbell photocatalysts with spatial redox region

Controllable Synthesis of Concave Cubic Au@TiO2 Core-Shell Nanoparticles for Plasmon-enhanced Photon Harvesting

Optimized Nanostructured TiO2 Photocatalysts

Titania is the most widely studied photocatalyst. In its mixed-phase configuration ( anatase–rutile form) – as manifested in the commercially available P25 Degussa material – titania was previously found to exhibit the best photocatalytic properties reported for the pure system. A great deal of published research by various workers in the field has not fully explained the underlying mechanism f...

Facile sonophotodeposition advanced synthesis of Pd–Au/TiO2 photocatalysts: application to selective oxidation of methanol to methyl formate

The well controlled fabrication of supported bimetallic nanoparticles has inspired material scientists in the design of new methodologies [1]. This study presents a systematic approach for the synthesis, characterization (TEM, XPS, XRD, UV-Vis), and evaluation of bimetallic nanoparticles Pd-Au supported on Titania-P90 which are highly active and selective in photocatalytic oxidation of methanol...

Controllable Synthesis and Tunable Photocatalytic Properties of Ti3+-doped TiO2

Photocatalysts show great potential in environmental remediation and water splitting using either artificial or natural light. Titanium dioxide (TiO2)-based photocatalysts are studied most frequently because they are stable, non-toxic, readily available, and highly efficient. However, the relatively wide band gap of TiO2 significantly limits its use under visible light or solar light. We herein...

Utilization of TiO2 photocatalysts in green chemistry*

Environmental pollution and destruction on a global scale have drawn attention to the vital need for totally new environmentally friendly, clean chemical technologies and processes, the most important challenge facing chemical scientists in the field of green chemistry. Strong contenders as environmentally harmonious catalysts are photocatalysts that operate at room temperature and in a clean m...
