Abstract

A novel fluoride free protocol for highly truncated anatase TiO₂ nanocrystals with exposed {001} facets by preferential adsorption of CO₃²⁻ ions is developed. Experimental observations were corroborated by first principle quantum chemical DFT calculations. The synthesized anatase TiO₂ showed improved photocatalytic activity.
