Highly active nonpromoted W-based hydrotreating catalysts are prepared through a molecular approach with a control of each step. This approach yields WS2 crystallites exhibiting hexagonal 2D morphology, which have been characterized by combining XPS and HR HAADF-STEM techniques and ab initio molecul...
