FeCl-Promoted Photocatalytic Cleavage of C-C Bond in Lignin and Lignin Model to Benzoic Acid.

Because of the complex structure and inherent inert chemical activity of lignin, it is still challenging to depolymerize lignin to obtain valuable chemicals efficiently. Here, we present an FeCl-promoted photocatalytic depolymerization strategy to realize the C-C oxidative cleavage of lignin model compounds at room temperature. The method generates benzoic acid and phenol compounds in high yields.

Effects of different light intensity on leaf color changes in a Chinese cabbage yellow cotyledon mutant.

Leaf color is one of the most important phenotypic features in horticultural crops and directly related to the contents of photosynthetic pigments. Most leaf color mutants are determined by the altered chlorophyll or carotenoid, which can be affected by light quality and intensity. Our previous study obtained a Chinese cabbage yellow cotyledon mutant that exhibited obvious yellow phenotypes in the cotyledons and the new leaves.
