Ni 2 O3与具有Bronsted酸中心和刘易斯酸中心的固体酸（如HZSM-5和H-β）复合可显著提高聚烯烃（包括聚丙烯和线性低密度聚乙烯）的阻燃性能。这主要是由于在燃烧的中间阶段，聚烯烃降解产物形成了大量的残炭。因此，扩散到火焰区的可燃组分的量很小。
Combination of Ni2O3 and solid acid with Bronsted acid sites and Lewis acid sites (such as HZSM-5 and H-beta) could dramatically improve fire retardancy of polyolefin, including polypropylene and linear low-density polyethylene. This is mainly attributed to the formation of a large amount of residual char from degradation products of polyolefin in the intermediate stage of combustion. Thus, the amount of flammable components diffusing into the flame zone was small.
