Converting water impurity in organic solvent into hydrogen and hydrogen peroxide by organic semiconductor photocatalyst

Graphene-Encapsulated CdS as a High-Performance Photocatalyst for H2O2 Production from Pure Water

“…In order to investigate the mechanism of photocatalytic H 2 O 2 generation over CdS-rGO@AQS, the electronic band structure of CdS was determined based on a combination of the light band gap gauged by UV–vis diffuse reflectance spectroscopy and Mott–Schottky plots . The relationship between the converted Kubelka–Munk function and the E g was computated by photon energy for the photocatalyst by the following formula: α h ν = A ( h ν − E g ) n As shown in Figure a, the energy gap for CdS is 2.31 eV. The band structure was further explored by Mott–Schottky and ultraviolet photoelectron spectroscopy measurements.…”

“…While in the photocatalysis of organic semiconductor DAnTMS (DAnTMS synthesized from 9,10-dibromoanthracene (DAn) and trimethylsilylacetylene (TMS)), the shapes of the TPV curves in different gas and solvent situations are different, indicating the inconformity of the reaction mechanism for DAnTMS. The difference values of the photovoltage intensity were compared to show that the reaction rate of H 2 O reduction is faster than that of H 2 O oxidation [125]. Liu et al prepared Ni 2 P/CDs composite for water photocatalytic-splitting [126].…”

Bifunctional carbon dots as cocatalyst and reactor decorating an organic photocatalyst for H2 production from water-splitting in an emulsion

“…[7][8][9] Compared with inorganic semiconductors, organic semiconductors have wider and stronger absorbance in the range of visible light and the molecular structure, and their photoelectrical properties can be tuned exibly and accurately by the design of the molecular structure. [10][11][12] However, organic semiconductors still suffer from the short life and the low mobility of photogenerated charges. [13][14][15] In addition, due to the hydrophobicity of most organic semiconductors, their photocatalytic performances are limited in water.…”
