Synthesis of dense porous layered double hydroxides from struvite

We report an atom economic synthesis of a new type of dense porous layered double hydroxides (SLDHs) using struvite which is a commonly produced undesirable waste in wastewater treatment plants. The obtained SLDHs exhibit significantly higher specific surface areas and larger pore volumes than conventional coprecipitated LDHs but retain a comparable particle density.

Automated summary

This study demonstrates a novel atom economic synthesis method for a new type of dense porous layered double hydroxides using struvite, a common waste product from wastewater treatment plants. The resulting SLDHs have significantly higher specific surface areas and larger pore volumes compared to conventional coprecipitated LDHs while maintaining a comparable particle density.
