Carbon dioxide conversion to chemicals and fuels based on two-dimensional based hybrid materials will present a thorough discussion of the physics, chemistry, and electrochemical science behind the new and important area of materials science, energy, and environmental sustainability. The tremendous opportunities for two-dimensional based hybrid materials in the photocatalytic carbon dioxide conversion field come up from their huge number of applications. In the carbon dioxide conversion field, nanostructured metal oxide with a two-dimensional material composite system must meet assured design and functional criteria, as well as electrical and mechanical properties. The whole content of the proposed review is anticipated to build on what has been learned in elementary courses about synthesizing two-dimensional nanomaterials, metal oxide with composites, carbon dioxide conversion requirements, uses of two-dimensional materials with nanocomposites in carbon dioxide conversion as well as fuels and the major mechanisms involved during each application. The impact of hybrid materials and synergistic composite mixtures which are used extensively or show promising outcomes in the photocatalytic carbon dioxide conversion field will also be discussed.

Carbon dioxide contributes significantly to both global warming and climate change, processes that inflict major environmental damage, which is why it is of much interest to find a material that can adsorb carbon dioxide before it enters the atmosphere. In our study, we use first-principles calculations based on the density functional theory to investigate the adsorption of carbon dioxide on two-dimensional materials due to their unique chemical and physical properties. The two-dimensional materials we used include aluminum nitride, defected aluminum nitride, and silicene. We observed a negative adsorption energy of carbon dioxide on all three materials, signifying a spontaneous adsorption. Our charge analysis reveals a charge transfer from the materials to the molecule in addition to a significant overlap between the projected density of states spectra of the interacting atoms, all indicating the formation of chemical bonds between the material and adsorbed molecule. Our findings thus suggest that all the materials we used could be an effective adsorbent for carbon dioxide; however, the defected aluminum nitride sheet formed stronger bonds with carbon dioxide compared to the pure sheet. The application of our research could help decrease the world’s carbon footprint by creating devices to capture carbon dioxide before it enters the atmosphere.
