Reactivity of Bioinspired Magnesium-Organic Networks under CO₂ and O₂ Exposure.

ABSTRACT: Photosynthesis is the model system for energy conversion. It uses CO₂ as a starting reactant to convert solar energy into chemical energy, i.e., organic molecules or biomass. The first and rate-determining step of this cycle is the immobilization and activation of CO₂, catalyzed by RuBisCO enzyme, the most abundant protein on earth. Here, we propose a strategy to develop novel biomimetic two-dimensional (2D) nanostructures for CO₂ adsorption at room temperature by reductionist mimicking of the Mg-carboxylate RuBisCO active site. We present a method to synthesize a 2D surface-supported system based on Mg²⁺ centers stabilized by a carboxylate environment and track their structural dynamics and reactivity under either CO₂ or O₂
