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.
