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

                    ??????????????????? conditions. In this paper, a series of? CdXZn1 - 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 (Cd0.78Zn0.22S), 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.
