Abstract

Abstract

Research into materials based hydrogen storage has grown significantly over the past decade. Of the wide variety of materials based hydrogen storage, AlH3 nanoparticles were chosen as the primary focus of this paper. AlH3 nanoparticles were synthesised by mechanochemical reactions of the 3LiAlH4 + AlCl3 using different LiCl:AlH3 volume ratios (0.76:1, 2:1, 5:1 and 10:1) at 77 K. The addition of LiCl as a buffer leads to the reduction of the synthesized AlH3 crystallite size and preventing high Al yields. Quantitative Rietveld results suggest the presence of an amorphous AlH3 phase in mechanochemically synthesized samples.

Abstrak

Penyelidikan ke dalam simpanan hidrogen berasaskan bahan telah berkembang dengan ketara sepanjang dekad yang lalu. Daripada pelbagai jenis penyimpanan hidrogen berasaskan bahan, nanozarah AlH3 telah dipilih sebagai fokus utama kertas ini. Nanozarah AlH3 disintesis melalui tindak balas mekanokimia 3LiAlH4 + AlCl3 menggunakan nisbah isipadu LiCl:AlH3 yang berbeza (0.76:1, 2:1, 5:1 dan 10:1) pada 77 K. Penambahan LiCl sebagai penimbal membawa kepada pengurangan saiz kristal AlH3 yang disintesis dan menghalang hasil Al yang tinggi. Keputusan Rietveld kuantitatif mencadangkan kehadiran fasa AlH3 amorf dalam sampel yang disintesis secara mekanokimia.
