Cobaloxime coenzyme catalyzing artificial photosynthesis for hydrogen generation over CdS nanocrystals

Water oxidation catalytic ability of polypyridine complex containing a μ-OH, μ-O2 dicobalt(iii) core

“…Accordingly, the development and utilization of renewable and environmentally friendly energy are needed [1][2][3]. Hydrogen is a promising alternative to traditional fossil fuels because it is a clean energy source with a high heat value [4,5]. Water splitting inspired by photosynthesis is considered an ideal pathway for the conversion of solar energy and water into hydrogen energy [6][7][8].…”

A Semiconductor‐Mediator‐Catalyst Artificial Photosynthetic System for Photoelectrochemical Water Oxidation

“…The role of the added base on band bending behavior at the semiconductor/electrolyte interface was also investigated by Mott‐Schottky (M‐S) analysis in the same medium [43,44] . As shown in Figure S10b, the flat band potential for FTO|Fe 2 O 3 is maintained at 0.22 V vs. NHE even after the addition of the carbazole with no evidence for a role by carbazole on band bending.…”

“…[40,41] This decrease in PL emission intensity suggests the suppressed charge recombination of Fe 2 O 3 , which should be ascribed to the possible hole transfer from Fe 2 O 3 to the attached carbazole molecule. [22,42,43]…”

Hybrid Photoelectrochemical Water Splitting Systems: From Interface Design to System Assembly

“…In the investigation of water redox mechanisms, a variety of techniques have been exploited thanks to the research efforts of a number of research groups. They include CV,85,96–98 UV–vis,97,99 nuclear magnetic resonance (NMR),98 electron paramagnetic resonance (EPR),100,101 mass spectrometry (MS)99 and TAS,102–104 X‐ray photoelectron spectroscopy (XPS),19 dynamic light scattering (DLS),93 in situ Fourier transform infrared spectroscopy (FTIR),105 in situ transmission electron microscope (TEM),106 X‐ray absorption spectra (XAS),80 and density functional theory (DFT) 64,107–109. Among the above experimental techniques, CV is widely used for redox potential analysis to determine whether a charge transfer pathway is thermodynamically favorable.…”

“…Compared with solid material, molecular catalyst generally wouldn't change the electronic states of semiconductor/electrolyte interface due to its thinness 56. In recent years, Shen and co‐workers reported three hybrid systems for photocatalytic solar water reduction and oxidation based on interfacial molecular catalysts and interfacial band bending engineering 97,131,132. More recently, they utilized nickel complex 5 to tailor p‐Si/electrolyte interface energetics 27.…”
