Electron Transfer Reduction by Hydrogen Creates Porosity in Tantalate Crystals and Produce Multifunctionality.

Contrary to partially substituted systems, WO molecular sieves that exclusively comprise a d transition metal ion and do not possess template ions in the cavity are a new class of materials for photocatalysis owing to their framework structure. Because WO thermodynamically lacks proton-reduction capability, exploring diverse synthetic approaches of other materials is desirable for facilitating utilization as H evolution and water splitting systems. Herein, we report an efficient approach for the protonation of AgTaO to afford HTaO for application as a H molecular sieve.
