An Organic Molecular Photocatalyst Releasing Oxygen from Water

ChemSusChem, 2019
AbstractArtificial photosynthesis employing solar energy is one of the best means of reaching a sustainable energy cycle, in which water is oxidized to oxygen and supplies electrons for fuel generation. The development of suitable oxygen evolution materials driven by sunlight is hence the most challenging research topic in the field of photocatalysis ...

A Metal–Organic Framework Stabilizes an Occluded Photocatalyst

Chemistry – A European Journal, 2013
Occlusion and confinement of a [Ru(bpy)3 ]Cl2 photocatalyst in the cavities of a γ-cyclodextrin (CD) metal-organic framework (MOF) does not affect the catalyst's activity but prevents its photodegradation. Additionally, the OH(-) ions and/or ROH groups present inside the CD-MOF act as electron donors and complete the catalytic cycle.

Organic–inorganic hybrid photocatalyst for carbon dioxide reduction

Faraday Discussions, 2017
Efficient hybrid photocatalysts for carbon dioxide reduction were developed from dye-sensitized TiO2 nanoparticles and their catalytic performance was optimized by ternary organic/inorganic components. Thus, the hybrid system consists of (E)-2-cyano-3-(5′-(5′′-(p-(diphenylamino)phenyl)thiophen-2′′-yl)thiophen-2′-yl)-acrylic acid as a sensitizer and fac-

High-Performance Photocatalysts for Organic Reactions

2019
The most important aim of modern organic chemistry is to replace the old, environmentally hazardous, expensive and less efficient processes with new, energy efficient routes of synthesis. In this regard, during the past 10 years, heterogeneous photocatalytic systems have been identified to have made it possible to perform green synthesis of a number of
