Highly selective CO2 photoreduction to CO on MOF-derived TiO2

Berend Smit, Christopher Patrick Ireland, Stavroula Kampouri

Metal-Organic Framework (MOF)-derived TiO2, synthesised through the calcination of MIL-125-NH2, is investigated for its potential as a CO2 photoreduction catalyst. The effect of the reaction parameters: irradiance, temperature and partial pressure of water ...

Enhanced Visible-Light-Driven Hydrogen Production through MOF/MOF Heterojunctions

Berend Smit, Pascal Alexander Schouwink, Fatmah Ebrahim, Kyriakos Stylianou, Christopher Patrick Ireland, Maria Fumanal Quintana, Stavroula Kampouri

A strategy for enhancing the photocatalytic performance of MOF- based systems (MOF: metal-organic framework) is developed through the construction of MOF/MOF heterojunctions. The combination of MIL-167 with MIL-125-NH2 leads to the formation of MIL-167/MIL ...

Light-active Metal-Organic Frameworks for Photocatalytic Hydrogen Evolution

Stavroula Kampouri

The general scope of this thesis lies in the application of MOFs in photocatalysis. MOFs demonstrate inherent properties â such as high porosity, tunable optoelectronic and catalytic properties, which render them promising candidates for photocatalysis. ...

Taking lanthanides out of isolation: tuning the optical properties of metal-organic frameworks

Berend Smit, Kevin Sivula, Nestor Guijarro Carratala, Kyriakos Stylianou, Gloria Capano, Andrzej Gladysiak, Christopher Patrick Ireland, Maria Fumanal Quintana, Stavroula Kampouri, Davide Tiana

Metal organic frameworks (MOFs) are increasingly used in applications that rely on the optical and electronic properties of these materials. These applications require a fundamental understanding on how the structure of these materials, and in particular t ...

Unraveling the synergy between metal-organic frameworks and co-catalysts in photocatalytic water splitting

Alfredo Pasquarello, Stefano Falletta, Kyriakos Stylianou, Stavroula Kampouri, Patrick Gono, Zhendong Guo

We investigate the synergy occurring in photocatalytic water splitting between the metal-organic framework MIL-125-NH(2)and two co-catalysts, namely NiO and Ni2P, by calculating their band edge alignment with respect to the redox levels of liquid water. Fo ...

On the Electronic and Optical Properties of Metal-Organic Frameworks: Case Study of MIL-125 and MIL-125-NH2

Berend Smit, Alfredo Pasquarello, Kyriakos Stylianou, Francesco Ambrosio, Gloria Capano, Stavroula Kampouri

The photo-active MIL-125 and MIL-125-NH2 metal-organic frameworks (MOFs), despite having a very similar crystalline structure, exhibit different optical behaviors. Luminescence in MIL-125 decays in about 1 ns, while for its amino counterpart, the lifetime ...

Photocatalytic Hydrogen Generation from a Visible-Light-Responsive Metal–Organic Framework System: Stability versus Activity of Molybdenum Sulfide Cocatalysts

Berend Smit, Andreas Züttel, Kyriakos Stylianou, Wen Luo, Daniele Ongari, Bardiya Valizadeh, Ngoc Tú Nguyên, Stavroula Kampouri, Ophélie Marie Planes

We report the use of two earth abundant molybdenum sulfide-based cocatalysts, Mo(3)S(13)(2-)clusters and 1T-MoS2 nanoparticles (NPs), in combination with the visible-light active metal-organic framework (MOF) MIL-125-NH2 for the photocatalytic generation o ...
