Abstract: Disclosed is a method of producing hydrogen (H2) 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 (H2) 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.

Abstract: Disclosed is a method of producing hydrogen from formaldehyde. The method includes mixing an aqueous base, formaldehyde, and a transition metal complex having a transition metal-halide bond to form a homogenous aqueous solution having a basic pH. The halide dissociates from the transition metal complex in response to the basic pH of the solution to produce hydrogen from the formaldehyde present in the homogeneous aqueous solution.

Abstract: Disclosed is a method of producing hydrogen from formaldehyde, the method comprising obtaining an aqueous mixture having a basic pH and comprising formaldehyde, an iron containing photocatalyst, and a base, and subjecting the aqueous mixture to light to produce hydrogen (H2) gas from the formaldehyde.
