Abstract: Methods, systems and kits for preparing carbamates as well as catalysts for preparing the carbamates, are disclosed. The methods for preparing carbamate can include providing a catalyst comprising cerium oxide (CeO2) and at least one metal selected from the group consisting of iron (Fe), manganese (Mn), titanium (Ti), cobalt (Co), aluminum (Al), zinc (Zn), calcium (Ca), tin (Sn), indium (In), and any combination thereof; contacting the catalyst with at least one amine and at least one alcohol to form a mixture; and contacting the mixture with carbon dioxide under conditions sufficient to form the carbamate.
