Transparent wood (TW) is a lightweight, energy-efficient material engendering optical functionalities in natural hardwoods. A scalable method of TW involves the photocatalytic depolymerization of lignin on chromophore residues. However, we recognize that the use of hazardous reagents renders the method impracticable without posing a risk to workers. Hence, the present study explores differing, nonhazardous reagents that can undergo the photocatalytic oxidation mechanism to achieve TW materials.
