Recently, researchers of the Chinese Academy of Sciences developed a multi-restricted one-step controllable synthetic doping method to prepare nitrogen-doped porous graphite with high separation selectivity for rare earth ions Olefin film. This research not only opens up a new way for the preparation of heteroatom-doped nanoporous graphene materials but also provides new ideas for the realization of highly selective membrane separation of rare earth ions, which has potential industrial application prospects.

China rare earth price is in the upward trend in late February, 2021 despite of low trading activity. Upstream and downstream enterprises in the industry chain have not yet fully resumed normal production at the end of the Spring Festival holiday.
