Interface engineering via temperature-dependent self-transformation on SnS2/SnS for enhanced piezocatalysis
Heterojunction has been widely used in vibration-driven piezocatalysis for enhanced charges separation, while the weak interfaces seriously affect the efficiency during mechanical deformations due to prepared by traditional step-by-step methods. Herein, the intimate contact interfaces with shared S atoms are ingeniously constructed in SnS2/SnS anchored on porous carbon by effective interface engineering, which is in-situ derived from temperature-dependent self-transformation of SnS2. Benefiting from intimate contact interfaces, the piezoelectricity is remarkably improved due to the larger interfacial dipole moment caused by uneven distribution of charges. Importantly, vibration-induced piezoelectric polarization field strengthens the interfacial electric field to further promote the separation and migration of charges. The dynamic charges then transfer in porous carbon with high conductivity and adsorption for significantly improved piezocatalytic activity. The degradation efficiency of bisphenol A (BPA) is 6.3 times higher than SnS2 and H2 evolution rate is increased by 3.8 times. Compared with SnS2/SnS prepared by two-step solvothermal method, the degradation efficiency of BPA and H2 evolution activity are increased by 3 and 2 times, respectively. It provides a theoretical guidance for developing various multiphase structural piezocatalyst with strong interface interactions to improve the piezocatalytic efficiency.
