[求助] 请问大家负载中的XCuB/SiO2怎么理解呀? 已有1人参与

The B2O3-modified Cu/SiO2 catalysts were prepared by incipient wetness impregnation of Cu/SiO2 precursor with aqueous solutions containing the
desired amount of H3BO3 (SCRC). After impregnation, these samples were dried overnight at 80 C and then calcined at 400 C in
static air for 4 h. The obtained catalysts are designated as xCuB/
SiO2, where the x represents the nominal mass loading of boron
请问大家x为1,2,3 怎么确定呀

负载的B的量,可以是理论计算的量,也或者是负载后经过表征分析得出的量。
