Acid Modification of the Unsupported NiMo Catalysts by Y-Zeolite Nanoclusters

Crystals, 2019
Unsupported NiMo catalyst has high hydrogenation activity due to its high active site distribution. However, low specific surface area and pore distribution greatly limit the efficient utilization of the active components. The Y-zeolite nanoclusters were

High-efficiency borohydride oxidation and oxygen reduction on titanium-supported Au(NiMo) catalysts for Alkaline fuel cells

Chemical Physics Impact
In this research, we used a straightforward and cost-effective methodology to fabricate a three-dimensional nickel-molybdenum (NiMo) thin-layer coating, sparsely decorated with gold crystallites, on a titanium substrate (denoted as Au(NiMo)/Ti).
