Abstract: A synthesis of the micro-porous silica gel and its application to preparation of catalysts for C2 oxygenates synthesis from syngas is invented. The small particles of silica gel which are, produced by sol gel process are heated in a basic solution, followed by drying and/or calcinations, and thus form micro-porous silica as catalyst support. The basic solution can be one or a mixed solution of hydroxides, carbonates, bicarbonates, formates and acetates of alkali metal and ammonium. The obtained micro-porous silica can be impregnated with the solutions of rhodium salt and other transition element salts (as promoter precursors), followed by drying and/or calcinations, thus forming a micro-porous silica supported rhodium based catalyst. The rhodium salt can be RhCl3 or Rh(NO3)3. The promoter precursors can be water-dissolvable transition metal salts, rare earth metals salts, alkali metal salts and alkali earth metal salts.
