Owe to the ever-increasing demand on noble metals in modern industrial, the extraction of noble metals from ores and

electronic wastes has already been a significant topic. Conventional extraction means involving surfactant, organic solvents

and toxic extracting agents, suffer from complex heterogeneous separation and extraction operation as well as

environmental pollution. Herein, a new carbon nanotubes (CNTs) hybrid membrane modified with eco-friendly and

reductive polyacryloyl hydrazide (PAH) is reported, integrating extraction of noble metal ions with heterogeneous emulsion

separation. The hybrid membrane with underwater superoleophobic surface can achieve one-step preferential extraction

of noble metal ions during oil/water emulsion separation, greatly simplifying the extraction operation. The reductive

extraction yields nanoparticles loaded in-situ on CNTs, which allows to evaluate precisely recovery performances by

monitoring resistance variation of hybrid membrane. Furthermore, the extracted hybrid membrane can be recycled for

catalytic conversion of organic contaminants as well as emulsion separation. The multi-functional hybrid membrane realizes

comprehensively recovery of noble metal ions and heterogeneous separation for further recycling utilization, showing great

potential for practical application towards simple and integrated recycling of noble metals.
