Although the catalytic activity of nano-gold surfaces for the reduction of nitro compounds has been known, the effect of their shape has been rarely evaluated. Here, the synthesis, characterization, and application of both gold nanoworms (GNW) and gold nanospheres (GNS) are described. Both GNW and GNS were characterized using SEM, TEM, UV–Vis, FTIR, and XPS spectroscopy. The catalytic efficiency of GNW with an average dimensions of 2 × 250 nm (D × L) towards the hydrogenation of nitrophenol, a pollutant present in industrial wastewater, is higher (TOF 3675 h⁻¹) than that of spherical GNS (10 ± 1 nm), for which TOF is 1838 h⁻¹ in water using NaBH₄ as the reductant. The selectivity of 4-aminophenol is 100% for both GNS and GNW.

尽管已知纳米金表面用于还原硝基化合物的催化活性，但很少评估其形状的影响。在此，描述了金纳米蠕虫（GNW）和金纳米球（GNS）的合成，表征和应用。GNW和GNS都使用SEM，TEM，UV-Vis，FTIR和XPS光谱进行了表征。平均尺寸为2×250 nm（D×L）的GNW对硝基苯酚（工业废水中存在的污染物）的催化效率高于球形GNS（10±1）（TOF 3675 ​​h ^-1） nm），使用NaBH ₄作为还原剂，在水中的TOF为1838 h ^-1。对于GNS和GNW，4-氨基苯酚的选择性均为100％。
