摘    要:以工业4号活性炭(AC4)为载体,采用浸渍法制备Cu-磺化酞菁钴(CoSPc)负载型活性炭,考察不同制备条件对其催化氧化净化PH3性能的影响,并采用N2物理吸附(N2-BET)、扫描电镜(SEM)、能量色散谱仪(EDS)、X线光电子能谱(XPS)等手段对改性活性炭进行表征。研究结果表明:当Cu2+浓度为0.1 mol/L,干燥温度为110 ℃,焙烧温度为350 ℃时改性炭对PH3的催化氧化净化效果最好;与以往研究的Cu2+改性活性炭相比,Cu-CoSPc负载型活性炭对PH3具有更好的净化脱除性能。

Abstract: In order to obtain a more effective modified activated carbon for the purification of PH3, the AC4-supported Cu-CoSPc modified activated carbon was prepared. The effects of preparation conditions on the catalytic oxidation purification properties of the modified activated carbon were studied, and it was characterized by N2 adsorption-desorption(N2-BET), scanning electron microscope(SEM), energy dispersive spectrometer(EDS) and X-ray photoelectron spectroscopy(XPS). The results show that when the catalytic oxidation purification properties for PH3 reaches the maximum at Cu2+ concentration of 0.1 mol/L, dryness temperature of 110 ℃ and cremation temperature of 350 ℃. The purification capacity of Cu-CoSPc modified activated carbon is much higher than that of the previous Cu2+ modified activated carbon.
