Visible-light active collagen-TiO2 nanobio-sponge for water remediation: A sustainable approach

Pollution owing to the dye house wastewater and negligent disposal of proteinaceous wastes are major threats to the environment. The conventional water treatment and solid waste management techniques are neither efficient nor cost effective. Here, we developed a collagen-TiO2 nanoparticles based pho...

TiO2 nanoparticles were functionalized (TIF) with 3-aminopropyltriethoxysilane for stabilizing type-I collagen fibers extracted from cowhide wastes. 13C-nuclear magnetic resonance (13C NMR) and Fourier-transform infrared (FT-IR) spectroscopic analyses confirm the amine functionalization on the surface of TiO2 nanoparticles.
