Catalysts are thoese molecules which are added to the reaction to spead it up. They actually don't take part in the reaction. Thier presence is enough!

You can have the eg of NICKEL. Thier magnetic field also affects the other molecules and forces them to react fast(up to some extent) and their molecular structure is also responsible.
