Undoped TiO2 and
Mn-doped TiO2 nanoparticles were prepared
by the sol–gel method. 50 mL of titanium(IV)isopropoxide (TTIP:
97% reagent grade, Sigma-Aldrich) was added to 50 mL of 2-propanol
(99.8%, RCI Labscan), and the solution was continuously stirred. Various
amount of manganese chloride (MnCl2·4H2O; 98.0%, Ajax Finechem Australia), including 0, 0.029, 0.058, and
0.087 grams, were dissolved in 10 mL of deionized water and added
to the TTIP solution. The pH of the mixture was adjusted to 2 by nitric
acid (70%, Ajax Finechem Australia). After 4 h of stirring, the mixture
was kept at 55 °C for 24 h and calcined at 400 °C for 2
h. Finally, undoped TiO2, 0.1, 0.2, and 0.3% Mn-doped TiO2 were achieved.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
