Study of low-nuclearity nickel catalysts prepared by liquid phase atomic layer deposition

Precious metal catalysts are crucial in industrial catalytic processes but are often limited by their scarcity and toxicity. In response, our study explores nickel-based catalysts synthesized using liquid-phase atomic layer deposition (L-ALD), an innovative method developed in our lab that allows precise control over metal dispersion at the atomic scale. We propose to use operando XAS techniques to investigate two novel catalysts: (1) nickel supported on MgO-Al₂O₃ for the dry reforming of methane (DRM), aiming to enhance selectivity toward either CO or H₂, and (2) nickel confined within the mesoporous structure of Al-MCM-41 for low-temperature hydrogenolysis of lignin.
