Abstract
Disclosed is a method of producing hydrogen (H) gas and calcium carbonate from formaldehyde. The method includes combining an aqueous base, formaldehyde, and a transition metal complex having a coordination bond between a transition metal and a leaving group to form a homogeneous aqueous solution having a basic pH, wherein the leaving group dissociates from the transition metal complex in response to light and/or the basic pH of the solution, producing hydrogen (H) gas and formate or a salt thereof from the formaldehyde present in the homogeneous aqueous solution, and producing calcium carbonate using the formate or salt thereof as a carbon source.
