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.

Electrochemical CO2 reduction towards value-added chemical feedstocks has been extensively studied in recent years to resolve the energy and environmental problems. The practical application of electrochemical CO2 reduction technology requires a cost-effective, highly efficient, and robust catalyst. To date, vigorous research have been carried out to increase the proficiency of electrocatalysts. In recent years, two-dimensional (2D) graphene and transition metal chalcogenides (TMCs) have displayed excellent activity towards CO2 reduction. This review focuses on the recent progress of 2D graphene and TMCs for selective electrochemical CO2 reduction into CO.

Abstract Graphene, as a successfully industrialized two-dimensional material, has greatly promoted the development of other two-dimensional materials, such as transition metal dichalcogenide (TMDs). 1T-TaS2 is a classical TMDs material, which presents metallicity at high temperature. It undergoes a variety of charge density wave (CDW) phase transitions during the temperature declining process, and presents insulating properties at low temperature. During the temperature rise period, 1T-TaS2 goes through a phase transition, from an energy band insulator to Mott insulator, followed by an insulation-metal phase transition. The complexity of 1T-TaS2 phase diagram encourages researchers to conduct extensive research on it. This paper, via means of resistance, magnetic susceptibility and other technical methods, finds out that the ultra-low temperature of 1T-TaS2 suggests additional complexity. In addition, with the angle resolved photoemission spectroscopy (ARPES) technique of in-situ alkali metal evaporation, this paper proposes that the 1T-TaS2 ultra-low temperature ground state may exist a combination of state and surface state. Our findings provide more experimental evidence for the physical mechanism of this system.
