- •
Hierarchical porous La2Zr2O7 monoliths were synthesized via a sol–gel process accompanied by phase separation.
- •
Adjusting the content of gelation and separation inducers can control the size of the pores.
- •
The mechanism of gelation process and competitive reaction between gelation and phase separation has been discussed.
- •
The evolution of pores in La2Zr2O7 monoliths was investigated.
