摘要:

将无定型磷酸铝在800℃高温下与氨反应,制备了不同氮含量的固体碱催化剂氮化磷酸铝,并用化学分析、比表面测定(BET)、傅立叶红外光谱(FTIR)和光电子能谱(XPS)等手段对产物进行了表征.结果表明,氮化产物保留了磷酸铝前体的高比表面,高温氮化过程中有P-NH2基团和P-NH-Al基团生成,且P-NH2基团较P-NH-Al基团易于生成,随着氮含量的增加,P-NH-Al基团所占比例增加,氮化过程有明显的磷的损失.化学分析表明,氮均匀地分布在样品的体相.

Abstract:

Amorphous aluminum phosphate was reacted with ammonia at 800°C to prepare aluminum nitride with solid base catalysts with different nitrogen content, and the products were characterized by chemical analysis, specific surface determination (BET), Fourier infrared spectroscopy (FTIR) and photoelectron spectroscopy (XPS). The results show that the nitriding product retains the high specific surface of the aluminum phosphate precursor, and there are P-NH2 groups and P-NH-Al groups in the high-temperature nitriding process, and the P-NH2 group is easier to generate than the P-NH-Al group, and with the increase of nitrogen content, the proportion of P-NH-Al group increases, and there is obvious phosphorus loss in the nitriding process. Chemical analysis showed that nitrogen was uniformly distributed in the bulk phase of the sample.
