- •
Al modified SBA-15 based supported Fe–W catalysts exhibited remarkable selectivity to ring-opening products in the hydrocracking of phenanthrene, in comparison to Ni–Mo/ɤ-Al2O3 sulfided catalyst.
- •
Enhanced mesoporosity in SBA-15 based mesoporous silica was possible by adding TMB (1,3,5-trimetilbenzene).
- •
The addition of small amounts of NH4F during the synthesis of SBA-15 yielded amorphous silica with wider pore size.
- •
Al post-synthesis incorporation method generated acidity in SBA-15.
