摘要： ????? Achieving green synthesis and transformation of organics is always? an?ambition?? of scientists under mild

??????????????????? conditions. In this paper, a series of? Cd_XZn_{1 - X} S (0 ≤ X ≤ 1) samples were synthesized by a simple

??????????????????? wet chemical ?method using cadmium nitrate, zinc nitrate and sodium sulfide as precursors ,?and were

??????????????????? thoroughly characterized by many techniques, including X-ray? diffraction, UV - vis absorption spectra,

??????????????????? nitrogen adsorption-desorption? isotherms, scanning electron microscopy, transmission electron

??????????????????? microscopy and? (photo)electrochemical measurements. The photocatalytic performance of the as-

??????????????????? prepared sampleswas evaluated by photocatalytic synthesis of Schiff base?compounds in the coupled

??????????????????? system of benzyl alcohol and nitrobenzene under? visible light irradiation. Results reveal that when X is

??????????????????? 0.78 (Cd_0.78Zn_0.22S), the? sample exhibits the highest photocatalytic performance. The yield of Schiff base?

????????????????? ? is 55.2% under visible light illumination for 4 h, and the theoretical yields of benzaldehyde and aniline

??????????????????? could reach 96.6% and 67.9%, respectively. The? quantum efficiency (QE) of the sample with k = 450 ±?

??????????????????? 10 nm is 15.8%. In? addition, many other Schiff base compounds were also synthesized from the? different

?????????????????? ?coupled systems of aromatic alcohols and nitrobenzene. A possible? reaction mechanism involving the

??????????????????? oxidation of benzyl alcohol to benzaldehyde? by photogenerated holes and the reduction of nitrobenzene to

??????????????????? aniline by photoinduced electrons, followed by a condensation reaction between? benzaldehyde and

??????????????????? aniline to generate Schiff base compound was proposed. It is? expected that the current work could offer

??????????????????? an avenue to fabricate a high- performance photocatalyst used in the fields of photocatalytic selective

??????????????????? organic transformations under mild conditions.
