- •
W-based hybrid nanocrystals (HNCs) were synthesized under moderate conditions.
- •
The HNC-derived catalysts had active phases with smaller size and higher stacking.
- •
NiO loading optimization can further tune the size and morphology of active phases.
- •
HNC-derived NiW catalysts with optimized NiO loading showed superior HDS selectivity.
