Summary of "Rational Synthesis of Amorphous Iron-Nickel Phosphonates for Highly Efficient Photocatalytic Water Oxidation with nearly 100% Yield."

Transition metal phosphonates present great potential in catalysis and other applications due to their versatile coordination chemistry and flexible structures. However, many of them grow into dense crystals with low practical use in catalysis. To circumvent this, a simple solvent ligation effect was successfully used to disrupt the growth of a model compound, Fe[(OH)(O 3 P(CH 2 ) 2 CO 2 H)]×H 2 O (MIL-37), into the extended 2D structure by replacing water with dimethylformamide (DMF) as the solvent during the synthesis. Due to the lack of -OH group which provides the corner-sharing (binding) oxygen atoms for the octahedra, amorphous and porous structure is formed. When Fe 3+ is partially replaced by Ni 2+ , the amorphous structure remains and the resultant binary metal catalyst displays excellent photocatalytic oxygen evolution activity with almost 100% yield achieved under visible light irradiation using [Ru(bpy) 3 ] 2+ as the photosensitizer. This study opens up new possibilities of using the simple solvent effect to synthesize high surface area metal phosphonates for catalytic and other applications .
