Atomically precise array of Nanopores in organic 2D membranes

Technology Overview:

Researchers at Leiden University have developed an entirely novel approach to the production of nanoporous graphene and other 2D atomic thin organic materials with nanopores in. The new technique has a number of major advantages over currently used lithography based techniques:

  • it allows for large numbers of pores;
  • it can produce small enough – sub nanometer – pores to match proton selectivity requirements for applications such as in fuel cells;
  • it is possible to finely tune the rim of the pore.

The new technique particularly offers great potential for the production of nanoporous membranes for direct-methanol fuel cells (DMFCs) of which both durability and power density could be improved significantly using tailored 2D membranes. Tailored 2D nanoporous materials could also be used for water purification and many other applications.

Key benefits

  • Lower production costs
  • Tailored size, shape and distribution of pores


  • Fuel cells
  • Catalysts
  • Water purification

Development stage

A prototype production facility is to be developed shortly.
