  • Efficient photocatalytic synthesis of l-glutamate using a self-assembled carbon nitride/sulfur/porphyrin catalyst

    摘要： Mimicking natural photosynthesis is a promising way to produce fine chemicals, yet there is a need for efficient catalysts. Here, we synthesized a photocatalyst made of self-assembled graphitic carbon nitride/sulfur/cobalt (III) tetraphenyl porphyrin, and we used this photocatalyst for production of the l-glutamate amino acid in 93.6% yield. Regeneration of the 1,4-dihydronicotinamide adenine dinucleotide cofactor under visible light reached 88.3%.

  • Energy Transfer from CdSe/ZnS Nanocrystals to Tetraphenyl Porphyrin

    摘要： CdSe/ZnS nanocrystals (NCs) and Tetraphenyl Porphyrin (TPP) are mixed uniformly to prepare CdSe/ZnS NCs/TPP complex. TPP can quench the fluorescent signal of CdSe/ZnS NCs. UV-Vis absorption spectra and fluorescence spectra are employed to analysis the energy transfer. The mechanism of energy transfer is the F?rster resonance energy transfer from CdSe/ZnS to TPP.
