The solid-state catalytic process contributes significantly to present human wealth and environmental protection. It allows for the manufacture of clean fuels and chemical products, as well as the reduction of harmful gas and liquid emissions into the atmosphere. The scientific community, the industrial sector, and society all recognise these characteristics. The mass and energy dimensions of a catalytic substance are important. It's possible to think of it as a process with inputs and outcomes. The material to be handled is referred to as mass input (i.e., raw materials to be converted into added-value ones, or into energy, or emissions to be treated). Because endothermic reactions use energy, heat might be considered an input.
