Lignin Confined in Wood Enhances Photocatalytic Efficiency by 23.08 Times

Researchers from Northeast Forestry University have made a groundbreaking discovery in the field of nanotechnology and photocatalytics, where they found that lignin confined in wood can significantly enhance the photocatalytic efficiency of CuO by 23.08 times. The study, published in the International Journal of Biological Macromolecules, demonstrates the potential of wood as a sustainable and renewable resource in photocatalytic applications.

The researchers employed a demethylation reaction to modify lignin in wood, creating a stable heterostructure with cuprous oxide (CuO) photocatalysts. Through the chelating effect of demethylated lignin, the CuO photocatalysts were anchored on the wood surface via an in-situ synthesis method. The study found that the sensitization effect of spatially confined lignin can increase the photocatalytic efficiency of CuO, making wood a promising material for high-value applications.
