catalysts which are in the same phase to that of reactants and products
Because palladium is a solid metal and the reactants are liquids or gases.
Heterogeneous refers to something that is composed of different or diverse elements. For example, a heterogeneous mixture is one in which the components are not uniform throughout. Heterogeneous can also describe a group of individuals with varied characteristics.
A catalyst is a substance that helps a chemical reaction happen faster without suffering any change. An example sentence is: Because of the catalyst, the project ending early.
No, brass is not a heterogeneous mixture. It is a homogeneous mixture composed of copper and zinc.

The heterogeneous catalyst is not mixed with the reactants.
The difference between a homogeneous and a heterogeneous catalyst is that in a heterogeneous catalyst, it is in a different phase from the reactants. However, in a homogeneous catalyst, it is in the same phase as the reactants.
heterogeneous and homogeneous are words used to describe a system, not a single element. For example, with regards to catalysis you could have a homogeneous catalyst which means one that works in the same phase as the reactant (i.e. both solid or both liquid or both gas) or a heterogeneous catalyst, which works in a different phase to the reactant, so a solid catalyst for a gaseous reactant etc.
For example the ammonia production; the magnetite catalyst is the most common.
Because palladium is a solid metal and the reactants are liquids or gases.
A heterogeneous mixture is composed of two or more components that are not evenly distributed and are easily observable. An example of a heterogeneous mixture is beef stew.

An example would be a mixture of flour and water. Heterogeneous mixtures have two different phases.
Under these conditions, platinum acts as a heterogeneous catalyst, meaning it is in a different phase from the reactants. Carbon-supported platinum catalysts (Pt/C) are commonly used in fuel cells. Magnesium, on the other hand, can act as a homogeneous catalyst under certain conditions.
