Reduction of CO 2 to methanol using renewable hydrogen is a promising but challenging strategy for carbon capture and utilization.
ConspectusHighly polarized compounds exhibiting intramolecular charge transfer (ICT) are used widely as nonlinear optical (NLO) materials and red emitters in organic light emitting diodes. Low-molecular-weight donor/acceptor (D/A)-substituted ICT ideal candidates for use the building blocks of hierarchically structured, multifunctional self-assembled supramolecular systems.

Spatial charge separation achieved on the anisotropic facets of high symmetry SrTiO<sub>3</sub>nanocrystals for highly efficient photocatalytic overall water splitting.
Plasmonic photocatalysis, stemming from the effective light absorbance and confinement of surface plasmons, provides a pathway to enhance solar energy conversion. Although plasmonic hot electrons in water reduction have been extensively studied, exactly how holes participate splitting reaction has not yet well understood. In particular, where oxidation is still illusive. Herein, taking Au/TiO2 as photocatalyst prototype, we investigated involved oxidation. The sites are positioned by...
Charge separation plays a crucial role in determining the solar-to-hydrogen conversion efficiency for photoelectrochemical water splitting. Of factors that affect charge separation, anisotropic transport property of semiconductors shows great potential promoting but it has received little attention. Herein, we report BiVO4 photoanodes with predominant [010] and [121] orientations demonstrate crystallographic-orientation-dependent solar oxidation. We found [010]-orientated photoanode...
Photocatalytic aerobic oxidation of hydrocarbons to ketones is an attractive route for synthesizing high-value-added chemicals. However, the main challenge photocatalytic reactions their low activity.

The 0D/1D graphitic carbon nitride (g-C3N4)/TiO2 heterostructures containing an interfacial oxygen vacancy layer were sequentially constructed by anodic oxidation, NaBH4 reduction, and vapor deposition methods. Visible light absorption was significantly improved via construction of the coupling with g-C3N4. Thus, g-C3N4/OV-TiO2 showed optimal photocurrent density as high 0.72 mA/cm2 at 1.23 V versus reversible hydrogen electrode under visible irradiation, 8-fold higher than data g-C3N4/TiO2...
Charge separation among different crystal facets of a semiconductor has been observed experimentally, but the underlying reasons behind this phenomenon are unknown. In work, activation energies carrier hopping and mobility electron/hole transport along seven low-index orientations bulk BiVO4 have calculated using small polaron model. The our previous experimental results reveal that there is parallel relationship between axis preferred accumulation on corresponding facets. It proposed...
Electron transfer processes from semiconductor to molecular catalysts was studied in a model hybrid photocatalytic hydrogen evolution system composed of [Co((III))(dmgH)2PyCl] (CoPy) and CdS under different pH conditions. Thermodynamic kinetic studies revealed that H2 high conditions (pH 13.5) can only account for the thermodynamically more favorable single-step simultaneous two-electron photoirradiated Co(III)Py produce unavoidable intermediate Co(I)Py, rather than two-step successive...
