Abstract:
1. A method for preparing a nitride nanomaterial, comprising: (A) providing a first precursor and a second precursor, wherein the first precursor is a transition metal precursor, a group IIIA precursor, a group IVA precursor or a mixture thereof, and a second precursor is a nitrogen-containing aromatic compound; and (B) heating the first precursor with the second precursor to form a nanocrystalline nitride material; wherein the transition metal precursor is (CH wherein the group IIIA precursor is boronic acid, boron bromide, aluminum nitrate, aluminum acetate, aluminum bromide, aluminum chloride, aluminum fluoride, aluminum ethoxide, aluminum i-propoxide, gallium(III) nitrate, gallium(III) acetylacetonate, gallium(III) bromide, gallium(III) chloride, gallium(III) fluoride, indium(III) nitrate, indium(III) acetate, indium(III) acetylacetonate, indium(III) bromide, indium(III) chloride, indium(III) fluoride or a mixture thereof; and wherein the group IVA precursor is furfuryl alcohol, germanium(IV) ethoxide, germanium(IV) bromide, germanium(IV) chloride, germanium(IV) iodide, tin(IV) chloride, tin(II) acetate, tin(II) acetylacetonate, tin(II) bromide, tin(IV) t-butoxide , tin(II) chloride, tin(II) fluoride, tin(II) ethoxide or a mixture thereof.
