Synthesis of a Titanium‐Containing Prussian‐Blue Analogue with a Well‐Defined Cube Structure and Its Thermal Conversion into a Nanoporous Titanium–Iron‐Based Oxide

Out of the blue: Ti-containing Prussian blue analogues with well-defined cube structures were synthesized using a commercially available block copolymer (F127). The successful conversion of Ti-containing PB analogues into nanoporous Ti–Fe-based oxide cubes was also demonstrated.
