Boosting heterojunction interaction in electrochemical construction of MoS2 quantum dots@TiO2 nanotube arrays for highly effective photoelectrochemical performance and electrocatalytic hydrogen evolution
MoS2 quantum dots (QDs) are loaded onto TiO2 nanotube arrays (NTAs) via a facile strategy of combining electrochemical exfoliation with electrophoretic deposition (EFED). The optimal MoS2@TiO2 NTAs exhibits a low onset potential (76 mV vs RHE) with the Tafel slope of 93 mV dec−1. The reported synthe...

| description | MoS2 quantum dots (QDs) are loaded onto TiO2 nanotube arrays (NTAs) via a facile strategy of combining electrochemical exfoliation with electrophoretic deposition (EFED). The optimal MoS2@TiO2 NTAs exhibits a low onset potential (76 mV vs RHE) with the Tafel slope of 93 mV dec−1. The reported synthesis strategy is suitable for the heterojunction construction of other two-dimensional layered materials and semiconductor composites with excellent photoelectric properties. |
