Particulate matter capturing via naturally dried ZIF-8/graphene aerogels under harsh conditions by Mao, Jiajun, Tang, Yuxin, Wang, Yandong, Huang, Jianying, Dong, Xiuli, Chen, Zhong, Lai, Yuekun

“…Here we designed a thermally stable PM filter by in situ anchoring of zeolite imidazole framework-8 (ZIF-8) on a three-dimensional (3D) network of reduced graphene oxide aerogel (rGA) through natural drying. Owing to high specific surface area, well-connected porous network of graphene aerogel, and large number of metal sites from ZIF-8/rGA, the capture efficiencies for PM2.5 and PM10 are over 99.3% and 99.6%, respectively, at ambient conditions, and the efficiencies remain high in harsh conditions (PM2.5 and PM10: >98.8% and >99.1%, respectively, at 200°C at a flow velocity of 30 L/min). …”
