Research highlights

▶ New Composites Supports were developed to obtain egg-shell catalysts. ▶ Composites Supports combine hydrophilic-hydrophobic dual properties. ▶ Composite Supports have higher mechanical resistance than commercial supports. ▶ Synthesized egg-shell catalysts with Composites Supports have a thin active layer. ▶ Pd-Composite are more active than Pd-commercial in pelletized supports form.
