High efficiency hierarchical porous composite microfiltration membrane for high-temperature particulate matter capturing
Abstract Porous intermetallic membrane with extensive interconnected pores are potential candidates as functional materials for high-temperature particulate matter (PM) capturing. However, fabrication of intermetallic membrane with a combined performance of high filtration efficiency and high-temper...
