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

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

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. ...

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

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

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

Alfredo Pasquarello, Gloria Capano, Berend Smit, Francesco Ambrosio, Kyriakos Stylianou, 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 ...
