Photocatalytic water splitting is a promising platform for clean and renewable energy generation from solar energy. Metal mixed anion compounds such as oxynitrides, oxysulphides, and oxyhalides have emerged as promising photocatalysts for water splitting, owing to their negative valence band maximum (VBM) compared to conventional oxides [1, 2]. Substantial mixing of the p-orbitals from the non-oxide anions (e.g., N-2p, Cl-3p) with the O-2p orbitals cause a negative shift in the VBM. Unfortunately, most mixed-anion compounds undergo self-oxidation of non-oxide anions by photogenerated holes, thereby imposing surface modifications to overcome the oxidative photo-corrosion [3, 4]. Herein, we present the structural and compositional nanoscale characterization of new tantalum-gadolinium (Ta-Gd) based
