Solid–liquid interface reassembly enhances surface piezoelectric properties: transition from the parallel interface O-MoS2 to the spherical interface ZnS@O-MoS2

Abstract

To address the increasingly pressing issue of climate change caused by CO2 emissions, we explore an interface reassembly technique to fabricate the spherical interface ZnS@O-MoS2 (oxygen-doped molybdenum disulfide) and investigate its performance in piezoelectric catalytic CO2 reduction. Through a series of meticulous experiments and first-principles calculations, this work elucidates the significant effects of the spherical interface ZnS@O-MoS2 in promoting the piezoelectric catalytic effects of the parallel interface O-MoS2, improving its electronic transport, and enhancing piezoelectric properties. The results indicate that the spherical interface ZnS@O-MoS2 achieves higher production rates of CH4 and CO, demonstrating an efficiency in piezoelectric catalytic CO2 reduction that is 3.5 times that of the parallel interface O-MoS2. Notably, the spherical interface ZnS@O-MoS2 exhibits exceptional performance in piezoelectric catalytic CO2 reduction, suggesting that enhancing the piezoelectric effect through solid–liquid interface engineering design significantly benefits CO2 reduction performance. This approach provides a pathway for developing future innovative interfaces to combat climate change.
