Abstract

original image

Tungsten-based bimetallic catalysts (W–M(8,9,10); where M(8,9,10) is Ni, Pd, Pt, Ir, Ru, or Rh) are found to be highly active and selective for the formation of ethylene glycol from cellulose. The cooperation between C[BOND]C cracking reactions over metallic tungsten and the hydrogenation of unsaturated intermediates over the transition metals M(8,9,10) results in a particularly high selectivity towards ethylene glycol, up to 75 %.
