Synthesis and characterization of In2O3 nanocube via a solvothermal-calcination route

In2O3 nanocubes have been generated by a two-step process, a simple solvothermal technique for In(OH)3 nanocubes and subsequent reaction with O2 to form the In2O3 nanocubes, which exhibit morphologies identical to the original In(OH)3 nanocube. The In(OH)3 nanocubes and the In2O3 nanocubes are well-crystallized single-crystal nanostructure. Under optimal conversion conditions, the final geometry features of In2O3 are predetermined by the size and morphology of the In(OH)3 nanocubes. The size of In(OH)3 nanocubes is effected by pH value of solution.
