Embodiments of the present invention relates to integrated catalyst systems and associated processes that directly converts carbon dioxide or carbohydrate to CO, methane, or other valuable chemicals at room temperature and atmospheric pressure, requiring no extra energy. The integrated catalyst systems are comprised of nitrogenous heterocyclic compounds and at least two metal elements, wherein one metal element needs to be active than the other one. The integrated catalyst systems can be applied to reduce carbon dioxide and carbohydrate at room temperature with considerable conversion efficiency. The reduction process involves the steps of: a) nitrogenous heterocyclic compounds performance as solvent/major catalyst, dual component as reducing agent / co-catalyst; b) introducing the above integrated catalysts into the reactor full of CO.sub.2 or carbohydrate, and keeping stirring the reacting system for 1 to 4 hours, without any illumination or heating; c) CO, methane, or other reduction product is achieved with a conversion efficiency of about 100%; d) the reduction products are gases, which can be directly separated from the system without any additional separation process or involving additional chemicals.
