The TiO2 nanofibers were synthesized by the electrospinning method [30 (link)]. The mixed solution of tetrabutyl titanate (C16H36O4Ti) (Hangzhou Bangyi chemical Co., Ltd., Hangzhou, China), poly vinylpyrrolidone (PVP) (Aladdin, Shanghai, China), acetic acid (Xilong chemical Co., Ltd., Shantou, China) and ethanol (Tianjin Damao chemical reagent factory, Tianjin, China) was served as the precursor solution for TiO2 nanofibers. The TiO2 nanofibers were prepared at a high voltage (18–20 kV) and a feed rate of 1mL h−1. The samples were dried at 80 °C for 24 h followed by the calcination at 550 °C for 3 h in air to remove PVP.
The carboxylic-TiO2 (C-TiO2) nanofibers were synthesized by grinding the TiO2 nanofibers and citric acid monohydrate (Tianjin Hengxing chemical reagent manufacturing Co., Ltd., Tianjin, China) with a 1:0.5 weight ratio, then the mixed powder was dispersed in 30 mL deionized water and was stirred for 6 h. The resulted C-TiO2 nanofibers were centrifuged, washed with deionized water three times, and dried in the oven (Tianjin Taisite instrument Co., Ltd., Tianjin, China) at 80 °C for 12 h. Finally, the different contents of C-TiO2 nanofibers (0, 5, 10, and 15 wt%) were mixed with NMP solvent to make colloidal TiO2.

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.
