Procedure | Characteristic Results |
---|---|
200 mL of 35% H2O2 at 60°C for 2 hrs, then 48 hrs at R.T. [27] | (i) Dense and amorphous HAp composite layer (ii) Similar characteristics to NaOH pretreatment (iii) Induced fast formation of uniform HA coating |
| |
10 mL of 5 M H2O2 at 60°C for 24 hrs. [32] | (i) Produced thicker and more porous oxide layer (~0.06 μm) (ii) Provided more favorable sites for CaP nucleation (iii) Formation of basic TiOH groups was accelerated |

5M H2O2/0.1 M HNO3 (pH 7) at 80°C for 20 min. [31] | (i) Anatase-type TiO2 oxide layer with very low crystallinity (ii) Obtained sponge-like morphology (iii) Homogenous and uniform formation of HAp clusters |
