Enhanced performance of molecular electrocatalysts for CO2 reduction in a flow cell following K+ addition

Autor: Shunsuke Sato, Keita Sekizawa, Soichi Shirai, Naonari Sakamoto, Takeshi Morikawa

Electrocatalytic CO2 reduction is a key aspect of artificial photosynthesis systems designed to produce fuels. Some molecular complexes can act as electrocatalysts for CO2 reduction and the performance of these compounds can be controlled by varying

Electrochemical CO2 reduction improved by tuning the Cu-Cu distance in halogen-bridged dinuclear cuprous coordination polymers

Autor: Naonari Sakamoto, Takamasa Nonaka, Takeshi Morikawa, Takeo Arai, Masataka Ohashi, Keita Sekizawa, Shunsuke Sato, Yusaku F. Nishimura, Kosuke Kitazumi

Cu dinuclear coordination polymers in which two Cu atoms are bridged by a halogen reduce CO2 to C2 products. The distance between the two Cu atoms is expected to affect the C–C coupling reaction efficiency, herein we propose that a shorter Cu-Cu di

Autor: Takeshi Morikawa, Shunsuke Sato, Keita Sekizawa, Taku Wakabayashi, Kenji Kamada, Jieun Jung, Susumu Saito, Hiroko Okuwa

Publikováno v: Synlett. 33:1137-1141

A novel mononuclear ruthenium (Ru) complex bearing a PNNP-type tetradentate ligand is introduced here as a self-photosensitized catalyst for the reduction of carbon dioxide (CO2). When the pre-activation of the Ru complex by reaction with a base was

Study of Excited States and Electron Transfer of Semiconductor‐Metal‐Complex Hybrid Photocatalysts for CO 2 Reduction by Using Picosecond Time‐Resolved Spectroscopies

Autor: Tomiko M. Suzuki, Shunsuke Sato, Takeshi Morikawa, Ken Onda, Shu Saeki, Keita Sekizawa, Ken ichi Yamanaka, Sei'ichi Tanaka

Publikováno v: Chemistry – A European Journal. 27:1127-1137

A semiconductor-metal-complex hybrid photocatalyst was previously reported for CO2 reduction; this photocatalyst is composed of nitrogen-doped Ta2 O5 as a semiconductor photosensitizer and a Ru complex as a CO2 reduction catalyst, operating under vis

Photocatalytic CO2 Reduction Using a Robust Multifunctional Iridium Complex toward the Selective Formation of Formic Acid

Autor: Keita Sekizawa, Shunsuke Sato, Takeshi Morikawa, Susumu Saito, Kenji Kamada, Shunichi Fukuzumi, Taku Wakabayashi, Jieun Jung

Publikováno v: Journal of the American Chemical Society. 142:10261-10266

A highly efficient tetradentate PNNP-type Ir photocatalyst, Mes-IrPCY2, was developed for the reduction of carbon dioxide. The photocatalyst furnished formic acid (HCO2H) with 87% selectivity toget...
