室内空气净化复合材料的研究进展

摘要

This paper reviews the research progress of composite materials for interior air purification. Among which, the air purification material through physical methods is used to absorb harmful gas with active carbon fibers, silica gel and zeolite. The adsorption activity of the material could be improved up to30 mg/g by varying its dispersion degree and morphology. Nano-titanium dioxide is employed in chemical type air purification material due to its catalytic degradation to harmful gas, and the degradation effects can be improved to99% byco-doping modification. Composite type composite which possesses both adsorption and photocatalytic performance, can effectively remove the harmful gases in the air such as aldehydes and aromatics with purification effect as high as99.3 to99.9%.%综述了室内空气净化复合材料的研究进展。其中，物理型空气净化复合材料主要利用活性碳纤维、硅胶和沸石等对空气中有害气体进行吸附，通过调节材料的形貌和分散度，对有害气体的吸附能力可达30 mg/g以上；化学型空气净化复合材料是利用纳米二氧化钛的催化作用，使空气中的有害气体发生化学反应而分解，通过共掺杂和改性等手段可使其对有害气体的分解度提高到99%以上；复合型空气净化复合材料兼具吸附性能和光催化性能，能够有效去除空气中醛类和芳香类等有害气体，净化效果可达99.3%~99.9%。
