In today's severe PM2.5 and VOCs pollution, white carbon black has shown amazing potential for environmental remediation. The porous structure white carbon black filter material developed by the XX team has been used to construct honeycomb shaped nanochannels through template method, with a specific surface area of 1200m ²/g and an adsorption capacity for formaldehyde that is five times that of activated carbon. More innovatively, the manganese based catalyst loaded on its surface can decompose formaldehyde into CO ₂ and H ₂ O at room temperature, avoiding secondary pollution. Actual testing shows that the air purifier equipped with this filter material has a filtration efficiency of 99.997% for 0.3 μ m particles, and the lifespan of the filter element is extended to three times that of traditional products. At present, this technology has partnered with brands such as Gree and Dyson to provide "nano level protection" for indoor air quality.
