高温下超导复合氧化物常被用作气固相氧化的催化剂，不适用于液-固相的低温反应，本文研究了La2-xSrxCuO4+/-lambda(x=0，0.1，0.7，1)复合氧化物对苯酚低温羟基化反应的催化作用，发现x值越小，催化活性越高，并对实验现象进行了机理解释。
Superconductor mixed oxides are often used as catalysts at high temperature in gas-solid phase oxidations and considered not suitable for lower temperature reactions in the liquid-solid phase; here the catalysis of La2-xSrxCuO4+/-lambda (x = 0, 0.1, 0.7, 1) mixed oxides in phenol hydroxylation at lower temperatures are studied, and we find that the value of x has a significant effect on catalytic activity: the lower its value, the higher the catalytic activity; a mechanism is proposed to explain the experimental phenomena.
