Cu‐Based MOF/TiO2 Composite Nanomaterials for Photocatalytic Hydrogen Generation and the Role of Copper

Advanced Functional Materials, EarlyView.
HKUST‐1/TiO2 composite materials show a very high photocatalytic hydrogen evolution rate which increases as a function of the irradiation time until reaching a plateau and even surpasses the performance of the 1%Pt/TiO2 material after three photocatalytic cycles.

Surface and interstitial Ti diffusion at the rutile TiO2(110) surface [PDF]

, 2010
Diffusion of Ti through the TiO2 (110) rutile surface plays a key role in the growth and reactivity of TiO2. To understand the fundamental aspects of this important process, we present an analysis of the diffusion of Ti adspecies at the stoichiometric ...

Atomic Size Misfit for Electrocatalytic Small Molecule Activation

Advanced Functional Materials, EarlyView.
This review explores the application and mechanisms of atomic size misfit in catalysis for small molecule activation, focusing on how structural defects and electronic properties can effectively lower the energy barriers of chemical bonds in molecules like H2O, CO2, and N2.

Degradation of Phenol in Pharmaceutical Wastewater using TiO2/Pumice and O3/Active Carbon

Bulletin of Chemical Reaction Engineering & Catalysis, 2020
Phenol is a toxic organic compound that detectable in the pharmaceutical wastewater, and therefore it should be eliminated. This study aims to degrade phenol in the pharmaceutical wastewater treatment using Advanced Oxidation Processes (AOPs) include the

Assessment of the Opacity of Titanium Dioxide Free Film Coating Formulations

British Journal of Pharmacy, 2023
Titanium dioxide (TiO2) is widely used as an excipient in pharmaceutical film coating formulations. In August 2022, the European commission (EC) adopted a ban on the use of TiO2 (E171) as a food additive. There is uncertainty around the implications of

Solvent Effects on the Adsorption Geometry and Electronic Structure of Dye-Sensitized TiO2: A First-Principles Investigation [PDF]

, 2012
The performance of dye-sensitized solar cells (DSSCs) depends significantly on the adsorption geometry of the dye on the semiconductor surface. In turn, the stability and geometry of the adsorbed molecules is influenced by the chemical environment at the
