摘要

We report the synthesis of boron nitride nanosheets (BNNS) with improved pollutant degradation, hydrogen evolution, and piezoelectric-sensing properties by growing MoS2 nanoflowers on their surfaces. Here, BNNS were first prepared via the urea-assisted ball-milling method, and then BNNS@MoS2 were synthesized using a solvothermal process. It was found that the amino groups had been successfully introduced into BNNS after ball-milling exfoliation. And compared to the original BN powder, BNNS were found to possess smaller nanosheet morphologies and more irregular edges. Through decorating the surfaces of BNNS with MoS2 nanoflowers, the prepared BNNS@MoS2 showed significantly better catalytic performance. We found that the MoS2 could effectively enhance the activities in methylene blue degradation and the hydrogen evolution reaction. The Tafel slopes of BNNS and BNNS@MoS2 were 369 mV·dec−1 and 160 mV·dec−1, respectively. We additionally investigated the piezoelectric response characteristics of BNNS@MoS2 heterostructures, and they possessed higher output voltages as compared to the BNNS.
