Molecular Design of Photocathode Materials for Hydrogen Evolution and Carbon Dioxide Reduction

Recent Developments in the Use of Heterogeneous Semiconductor Photocatalyst Based Materials for a Visible-Light-Induced Water-Splitting System—A Brief Review

“…Applications by the use of high Voc with the tandem structure are reported [231][232][233][234][235][236][237][238]. There are several review papers about using advanced organic and carbon-based materials [239][240][241][242][243][244][245][246][247][248], while the present paper focused only on the heterogeneous organic semiconductor photocatalysts. Among these heterogeneous photocatalysts, the conjugated microporous polymers (CMPs) have been recognized as photocathodes for H 2 evolution from water to support a sacrificial electron donor.…”

High performance photoanodic catalyst prepared from an active organic photovoltaic cell – high potential gain from visible light

“…If the separated charge in its active layer can be utilized in chemical reactions directly without collection by electrodes, it would be a simple device for photoenergy conversion and have great merit to use the photon energy. From such a viewpoint, the research field of organic photoelectrochemical cells (OPECs) [2][3][4][5][6][7][8][9][10][11][12][13][14][15] and organophotocatalysts [14][15][16][17][18][19] has been refocused recently, while pioneer research started more than 30 years ago. 20 A recent trend is metal or metal oxide coating on bulk heterojunction (BHJ) OPVs to construct OPECs and its efficiency enhancement, [2][3][4][5][6] while the combination with rare metal is not so attractive for the choice of organic active layer.…”
