In the current study, Anatase/rutile TiO2 and Anatase/rutile TiO2@Glucose composites were successfully prepared by a simple method using mechanical technique. The as-prepared composite materials powders were characterized by Powder X-ray diffraction analysis (PXRD), Scanning electronic microscopy (SEM) and Solid-state UV-visible spectroscopy. X-ray patterns showed the fractional phase transformation from TiO2 anatase to rutile. SEM observations revealed that the particle shape was affected by ball milling process. EDS analysis exhibits quantitatively the elemental composition of Ti and O. UV-Visible spectroscopy confirmed that the bandgap is slightly affected using Tauc.

Keywords: Anatase/rutile, composite, TiO2, Mechanical technique, TiO2-Glucose and gap energy.

Q from Dr. Fang
A nice paper.
What is the role of glucose in the stated TiO2 milling process? Does glucose play a chemical role, or it just acts as a medium (like NaCl) to reduce the TiO2 particle size? Thanks.
