Natural phosphates are an important natural resource in Morocco, which need to be valorized; they can be used not only as primary raw material to produce the fertilizers but also as catalysts. In this work, we have prepared natural phosphate-supported nickel chloride (NiCl2/NP). This material was effectively used as a heterogeneous catalyst in the presence of sodium borohydride as a reducing agent. The reaction was carried out at room temperature in an aqueous medium. The catalyst showed an excellent activity for the reduction of aromatic nitro compounds under simple conditions along with good usability.
