Surface modification of titanium membrane by chemical vapor deposition and its electrochemical self-cleaning

► A new composite membrane Ti/BDD, made by depositing CVD (chemical vapor deposition) boron-doped diamond (BDD) film on titanium(Ti) membrane to modify porous titanium membrane surface, is brought forward. ► Preparation of Ti/BDD composite membrane and its application in membrane cleaning is discussed in this paper. ► Results shows that based on the unique electrochemical properties of BDD, cleaning level of this composite Ti/BDD membrane is significantly increased, making membrane life and efficiency improved prominently.
