Recent progress in water remediation and dye removal on one-dimensional nanomaterials

One-dimensional nanomaterials possess diverse functional and structural properties. Hence, they have been employed broadly in various catalytic fields including, water splitting, CO₂ capture, photodegradation of dyes, supercapacitors, metal-ion batteries, and solar cells. Various 1D nanomaterials have been synthesized in the past few years with different morphologies and sizes. Compared to other higher dimensional materials, these 1D materials have been given prominence due to their larger surface area, high aspect ratio, and better electronic transport. In this chapter, we have selectively discussed the dye degradation on 1D Ti, Zn, Cd, and Cu-based photocatalysts. This chapter highlights the intriguing factors that should be considered in designing new photocatalysts, including higher surface area, aspect ratio, and the optimized concentrations of the dopants.
