Formaldehyde(HCHO)is a common indoor gaseous pollutant,and long-term exposure to it may cause serious damage to the human immune *** degradation of HCHO is a promising ***,most photocatalysts have the disadvantage of rapid recombination of photo-generated electron-hole *** this work,the recombination of photogenerated electron holes was proposed to inhibit through the piezoelectric effect.A two-dimensional(2D)piezoelectric material,2H-MoS_(2),was selected to investigate the catalytic performance for HCHO degradation by the synergy of the piezoelectric and photocatalysis *** results show that the piezoelectric effect can induce the polarization in 2H-MoS_(2) and inhibit the recombination of photogenerated electron-hole pairs,thus improving the photogeneration of hydroxyl radicals for HCHO ***,the piezoelectric-photo-catalysis synergistic effect based on density functional theory(DFT)calculation was proposed to elucidate the HCHO degradation *** work could provide important guidance for the development of effective catalysts for HCHO degradation and the application of 2D piezoelectric materials.
