Porous layered nano-supports are a type of high specific surface area support system constructed based on layered materials such as single-layer hydrotalcite, often presenting petal-like porous structures with good dispersibility and uniform pore size distribution.

This type of material is widely used in catalytic cracking, hydrogenation, dehydrogenation, organic synthesis, and polymerization reactions, helping to improve the metal loading capacity and catalytic activity of catalysts.

Additionally, its structural characteristics also endow certain flame retardant and smoke suppression properties, helping to improve system operational safety in high-temperature reaction environments, suitable for catalytic systems in petrochemical, fine chemical, and environmental governance fields.
