Abstract : nano tio2 was dip - coated on active air purification sieve of active carbon. the purification effect of this sieve against various polluting gases were investigated. the result showed that purification effects on h2s, nh3, hcho, co, and toluene were notably enhanced throush degradation of pollutants by photocatalysis agent under uv irradiation, which resulted in enhanced purification ability of active carbon
文摘:採用浸塗法在活性炭空氣凈化網上負載納米二氧化鈦，在紫外光的照射下，凈化網對一氧化碳、甲醛、硫化氫等污染物的凈化能力明顯增強，對比實驗表明，在紫外光照射下光催化劑使被吸附的污染物發生降解反應而提高活性炭的凈化能力。Nano tio2 was dip - coated on active air purification sieve of active carbon. the purification effect of this sieve against various polluting gases were investigated. the result showed that purification effects on h2s, nh3, hcho, co, and toluene were notably enhanced throush degradation of pollutants by photocatalysis agent under uv irradiation, which resulted in enhanced purification ability of active carbon
