Exploration into the Syntheses of Gallium‐ and Indiumborates under Extreme Conditions: M (5)B(12)O(25)(OH): Structure, Luminescence, and Surprising Photocatalytic Properties

Explorative solid‐state chemistry led to the discovery of the two new compounds Ga(5)B(12)O(25)(OH) and In(5)B(12)O(25)(OH). Extreme synthetic conditions within the range of 12 GPa and a temperature of 1450 °C realized in a Walker‐type multianvil apparatus resulted in the formation of an unprecedent...

description Explorative solid‐state chemistry led to the discovery of the two new compounds Ga(5)B(12)O(25)(OH) and In(5)B(12)O(25)(OH). Extreme synthetic conditions within the range of 12 GPa and a temperature of 1450 °C realized in a Walker‐type multianvil apparatus resulted in the formation of an unprecedented tetragonal structure with the exclusive presence of condensed BO(4) tetrahedra, forming cuboctahedral cavities. Doping of these cavities with Eu(3+) in In(5)B(12)O(25)(OH) yielded in an orange–red luminescence. Photocatalytic tests of In(5)B(12)O(25)(OH) revealed a hydrogen production rate comparable to TiO(2) but completely co‐catalyst free.
