Abstract

En 中文

• Hydrolysis lignin as both a support and a reducing agent for Cu2O. • Aminosilane functionalisation promoted Cu2O nanowire growth and stability. • Anisotropic growth of Cu2O nanowires due to the amino environment. • Improved performance due to interfacial interactions at lignin-Cu2O interface. • Efficient, reusable visible-light-driven degradation of 2,4-D from agrowastewater.
