The synthesis of artificial leaf is being probed to trap solar energy. Model reaction of the nickel and all iron based hydrogenase enzymes, graphene based composites are under investigation including water splitting to harvest energy. It has been shown that carbon dioxide binds magnesium of chlorophylls and such complex has been modeled to facilitate the photochemical reaction at lower energy and thus shown thermodynamically feasible. Such demonstration established the proposal of Willstatter.
