亚硝酸盐是一种常见于饮用水中的污染物,一般产生于农业化肥的过度使用。近日,来自莱斯大学的化学工程师们发现了一种金钯纳米粒子,它可以迅速分解存在于饮用水中的常见污染物——亚硝酸盐。这种通过纳米技术加工出来的催化剂要比之前研发出的钯和氧化铝催化剂的效果好7.5倍之多。金钯催化剂催化亚硝酸盐反应示意图见图1。 Nitrite is a pollutant that is commonly found in drinking water and generally results from excessive use of agricultural fertilizers. Recently, chemical engineers from Rice University discovered a gold-palladium nanoparticle that quickly decomposes nitrite, a common pollutant found in drinking water. This nanotechnology-based catalyst is up to 7.5 times better than previously developed palladium and alumina catalysts.
