Fluorescent-brightener-mediated thiol-ene reactions under visible-light LED: A green and facile synthesis route to hyperbranched polymers and stimuli-sensitive nanoemulsions

Nano Metal-Containing Photocatalysts for the Removal of Volatile Organic Compounds: Doping, Performance, and Mechanisms

“…The degradation mechanism is presumed as follows, the •OH extracts hydrogen from formaldehyde to form the •CHO; and the •CHO can be further oxidized to a carboxylic acid in two ways; then, the carboxylic acid is further oxidized and decomposed into CO 2 and H 2 O. In fact, for some difficult-to-degrade VOCs such as benzene and toluene, the PCO process often cannot directly mineralize them into CO 2 and H 2 O, but ends in corresponding acids, aldehydes, and ketones [47].…”

“…The doped noble metal elements like Pt can inhibit the production of toxic intermediate by-products in the PCO process. Wu Q. et al [47] synthesized Pt/TiO 2 nanoparticles by a modified photo-deposition method. The photocatalytic experiments of formaldehyde-benzene and formaldehyde-xylene showed that the doped Pt could successfully inhibit the formation of toxic methyl phenol.…”

Revealing the photoredox potential of azulene derivatives as panchromatic photoinitiators in various light-initiated polymerization processes

“…Dye molecules that are suitable for this purpose should strongly absorb in the spectral region corresponding to the emission wavelengths of Vis-LED light sources and should have relevant electrochemical properties. [27][28][29][30][31][32] Despite the fact that metal complexes (e.g., ruthenium or iridium complexes) have been incorporated into photoinitiating systems for polymer synthesis under extremely mild irradiation conditions such as sunlight, fluorescent bulbs, or LED bulbs, these materials are either prohibitively expensive or difficult to synthesize. A more accessible solution is the use of organic dyes, which have a simpler synthesis pathway, are less toxic and exhibit improved stability and solubility.…”
