초록 Hydrogenation of silicon tetrachloride (SiCl4) to trichlorosilane (SiHCl3) using carbon-based catalysts is studied. The results show that surface functional groups that result from the defect sites of the carbon catalysts play an important role in producing SiHCl3. Because the metal-carbon composites obtained by treating sucrose and transition metals at high temperature in the N2 flow have more defect sites, they display an increased SiHCl3 yield. Elemental analysis of the catalyst and reaction results demonstrate that there is a very good correlation between the SiHCl3 yield and the amount of deposited silicon during the induction time, and the SiHCl3 yield and the accumulated amount of deposited Si species rapidly change initially and then reach a stable value. Hydrogenation of SiCl4 to SiHCl3 in metal-grade silicon (mg-Si) powder is known to give a higher equilibrium conversion of SiCl4.
