催化剂在当代化学、生物科学以及材料科学中发挥着重要的作用 .优良的催化剂表现为高选择性和高效率 .尤其是酶催化剂 ,其具有突出的选择性与催化效率 ,并且反应条件温和 ,是一般化学催化剂所难以比拟的 .现代化学一个很重要的内容 ,是识别小分子催化剂 ,使其能模拟酶 ,以加速 Catalysts play an important role in modern chemistry, biological sciences and materials science.Excellent catalysts show high selectivity and high efficiency.Especially the enzyme catalyst, which has outstanding selectivity and catalytic efficiency, and the reaction conditions are mild, is General chemical catalyst is difficult to compare.Modern chemistry is a very important content is to identify the small molecule catalyst to enable it to mimic the enzyme to speed up
