In this article, we report a new type of ligninbased wood-like aerogel filters composed of aligned micrometer-sized pores and cross-linked lignin-based cell walls, as well as their air filtration-related properties. The aerogel filters were prepared via facile unidirectional ice-crystal-induced selfass...
