碳载CuTAPP的ESR研究(Ⅱ)

ESR STUDIES OF CuTAPP SUPPORTED ON ACTIVE CARBON (Ⅱ)

本文利用ESR技术详细研究了室温至150℃范围内CuTAPP在碳表面的行为。提出了铜卟啉在碳表面吸附水膜中的二维扩散机理。对较高温度处理后铜卟啉的ESR也作了简要报道。

ESR studies were carried out in detail to investigate the changes of CuTAPP (cppper tetra-(p-trimethylanmoniumphyenl) porphine iodide) supported on active carbon during room temperature shelving and heat-treatment.Between room temperature and round 50℃, the resolution of the ESR spectra was found to vary with temperature and relative humidity reversibly. A mechanism of two-dimensional diffusion of the macrocyclic compound in the adsorbed liquid film was suggested to interprate the change in spectral resolution. The ESR spectra after heat-treatment at temperatures ranging from 150 to 6000℃ were also reported and discussed briefly.
