Fabrication of directly 2D Z-scheme CuTiO3/g-C3N4 with high photocatalytic activities for CO2 reduction and hydrogen production

Photocatalysts based on Z-scheme heterostructure have been extensively investigated for CO2 reduction and hydrogen production, which solve the problem of high electron-hole pair complexation and low reduction and oxidation capacity in photocatalysts. Here, two-dimensional CuTiO3/g-C3N4 (CTO/CN) photocatalysts with directly Z-scheme heterostructure are prepared by effective manipulation of different components of CuTiO3 (CTO) nanoparticles on 2D (two-dimension) porous g-C3N4 (CN) nanosheets via in-situ growing strategy. Benefited from the special electronic structure, it demonstrates that the 4.0 % CTO/CN sample has an excellent photocatalytic activity for the reduction of CO2 to H2 (at a speed of 19.56 μmol g−1 h−1) and CO (at a speed of 19.93 μmol g−1 h−1), which are upper than those of pure g-C3N4 by 43.5 and 17.1 times, respectively. Furthermore, the 4.0 % CTO/CN sample exhibits utstanding performance in electrocatalytic hydrogen production. This synthetic strategy is useful for constructing a 2D Z-scheme heterostructure for applications in energy-related areas.

Synthesis of graphene-based nanomaterials and their application in energy-related and environmental-related areas

As a fascinating two-dimensional carbon allotrope, graphene has triggered a ‘gold rush’ all over scientific research areas especially since the Nobel Prize for Physics in 2010. To exploit the prominent properties of graphene-based nanomaterials, two important problems are focused in this review: one is the synthesis of these graphene-based nanomaterials with different kinds of well-defined structures, and the other is the effective application of them as active nanomaterials in functional devices or processes. In this critical review, from the viewpoint of chemistry and materials, we give a brief overview of the recent significant advances in the synthesis of graphene-based nanomaterials and their applications in energy-related areas and environmental pollution remediation areas, including supercapacitors, lithium ion batteries, solar cells, adsorption, and degradation of organic/inorganic pollutants from large volumes of aqueous solutions in environmental pollution cleanup. The main challenges and perspectives of the materials for future research are also discussed.

Chemical Approaches toward Graphene‐Based Nanomaterials and their Applications in Energy‐Related Areas

A 'gold rush' has been triggered all over the world for exploiting the possible applications of graphene-based nanomaterials. For this purpose, two important problems have to be solved; one is the preparation of graphene-based nanomaterials with well-defined structures, and the other is the controllable fabrication of these materials into functional devices. This review gives a brief overview of the recent research concerning chemical and thermal approaches toward the production of well-defined graphene-based nanomaterials and their applications in energy-related areas, including solar cells, lithium ion secondary batteries, supercapacitors, and catalysis.
