Immobilization of a cobalt catalyst on fullerene in molecular devices for water reduction.
A cobalt-based molecular catalyst was successfully grafted to a fullerene derivative via 'click' chemistry on an electrode for both electro-catalytic and light driven water reduction. Using an organic photovoltaic electrode immobilized with a cobalt catalyst as the photocathode, the photoelectrochemical cell displayed a stable photocurrent.
متن کاملA robust and efficient cobalt molecular catalyst for CO2 reduction.
Visible-light driven CO2 reduction is considered to be a sustainable energy source. However, earth-abundant molecular catalysts with high efficiency and robustness towards solar-driven CO2 reduction are limited. Herein, we report a cobalt complex supported by a tetradentate tripodal ligand, which demonstrates catalytic solar-driven CO2 reduction with TON(CO) > 900 over 70 h in the presence of a...
متن کاملPhotoswitchable stable charge-distributed states in a new cobalt complex exhibiting photo-induced valence tautomerism.
We report the synthesis and magnetic and photomagnetic behaviour of a novel valence tautomeric cobalt complex, [Co(3,5-dbbq)2(μ-bpym)] (1) (3,5-dbbq = 3,5-di-tert-butyl-1,2-benzoquinone and μ-bpym = 2,2'-bipyrimidine). The synthesis is performed by reacting Co2(CO)8 and μ-bpym in the presence of the ligand 3,5-dbbq in a mixed solvent under inert atmosphere. The magnetic behavior clearly shows t...
متن کاملCatalyst deactivation
The fundamentals of catalyst deactivation are presented in this review. The chemico-physical aspects concerning the various deactivation causes (i.e. poisoning, sintering, coking, solid-state transformation, masking, etc.) have been analyzed and discussed, along with the mathematical description of the deactivation phenomena. # 1999 Elsevier Science B.V.
