Oxygen vacancies and Bi2S3 nanoparticles co-sensitized TiO2 nanotube arrays for enhanced photoelectrochemical sensing of chlorpyrifos

[Display omitted] •Oxygen vacancies were introduced into TiO2 nanotube arrays by heat-treating in argon atmosphere.•Bi2S3 nanoparticles were deposited on TiO2 nanotube arrays to form the heterojunction.•The sensitive detection of chlorpyrifos was achieved with Bi2S3/Vo-TNTAs heterojunction based-PEC...
