nickel 2 phosphate is an inorganic compound with the formula Ni3(PO4)2. It is a mint green paramagnetic solid. It is not soluble in water. It is a very effective adsorbent for heavy metals like nickel (Ni) cations and lead ions from polluted water. It is also an effective catalyst in the reduction of nitrobenzenes. It is used in electroplating. It is also a colorant for oil and water paints. It is found as a powder in laterite and magmatic sulfide ores. It is also a component of nickel batteries. It is toxic if inhaled. It can cause skin irritation and allergic reactions in humans. It is also a carcinogen.
Open framework porous materials continue to dominate commercial applications in catalytic chemistry but the chemical diversity of open-framework inorganic structures has expanded into new compositional domains [1]. Non-aluminosilicate phosphates have received increasing attention, and several crystalline and microporous nickel phosphates have been reported. [2]
The VSB-n series of nickel phosphates are particularly interesting because of their high porosity, high oxygen uptake, and reactivity towards hydrogen molecules. The chemical structure of these materials has been investigated using a combination of BET, temperature programmed desorption and inelastic neutron scattering measurements.
The results show that VSB-n has a higher porosity than many other porous nickel compounds, with porosities ranging from 2.18 to 6.08
