摘要：
The acid properties of layered Me phosphates (MeTi, Ge, Zr, Sn) were determined by NH3 temperature-programmed desorption. Careful establishment of the preheating conditions suppressed interference from NH3 intercalation and allowed the surface acidity to be measured. A scale of acidity strength in line with the catalytic behaviour of these phosphates in acid-catalysed reactions was obtained. © 1990.
