In situ construction of N/Ti3+ codoped triphasic TiO2 layer on TiO2 nanotube arrays to improve photoelectrochemical performance

In situ growth of N/Ti3+ codoped triphasic TiO2 layer on TiO2 nanotube arrays to construct homojunctions is achieved via hydrothermal reaction of TiN and TiO2 nanotube arrays and better photo-electrochemical performance is demonstrated.402
