The hexagonal copper-tin alloy (Cu-Sn) nanoplates were synthesized using a high temperature solvent method, the length of six equilateral edges of hexagonal Cu-Sn nanoplates was 23 nm, and the thickness was 13 nm. The obtained hexagonal Cu-Sn nanoplates were highly monodisperse and allowed the formation of nanoarrays arranged with long-range order. The hexagonal Cu-Sn nanoplates exhibited high catalytic activity on catalytic hydrogenation of 4-nitrophenol to 4-aminophenol. Due to the promotion effect of Sn, the apparent rate constant (ka) of hexagonal Cu-Sn nanoplates was three times that of Cu nanoparticles. The density functional theory (DFT) calculations and experimental results demonstrated that Sn could promote the coordination process of -NO2 of 4-nitrophenol with Cu-Sn nanoplates and contribute to activation of 4-nitrophenol. In addition, the hexagonal Cu-Sn nanoplates showed high stability and reusability for the reduction reaction, good adaptability in different pH and the ionic strength, and wide applicability for the degradation of methylene blue, methyl orange, and rhodamine B, even in the industrial wastewater, suggesting that the Cu-Sn nanoplates are promising catalysts in organic industry wastewater treatment.

采用高温溶剂法合成了六方铜锡合金（Cu-Sn）纳米板，六方Cu-Sn纳米板的六个等边边的长度为23 nm，厚度为13 nm。所获得的六角形Cu-Sn纳米板高度单分散，并允许形成以长距离顺序排列的纳米阵列。六角形的Cu-Sn纳米板对4-硝基苯酚催化氢化为4-氨基苯酚具有较高的催化活性。由于Sn的促进作用，六角形Cu-Sn纳米板的表观速率常数（ka）是Cu纳米颗粒的三倍。密度泛函理论（DFT）计算和实验结果表明，Sn可以促进4-硝基苯酚的-NO2与Cu-Sn纳米板的配位过程，并有助于4-硝基苯酚的活化。此外，
