Energy shortage and environmental pollution have become two serious problems in the process of sustainable development. Developing novel materials with distinctive properties is an effective method to relieve environmental pressure. Since graphene was first exfoliated from graphite in 2004, ultrathin two-dimensional (2D) nanomaterials have become the most important nanomaterials in energy and environmental fields. Due to electron confinement in two dimensions, the 2D nanomaterials exhibit unique properties such as quantum-size effect, excellent optical transparency, electrical and thermal conductivities, leading to excellent and unexpected performances. Consequently, the development of novel 2D based nanomaterials toward energy and environmental applications, further improvement of the performance and efficiency of these systems, and further understanding of 2D structure-property relationships are promising frontiers and offering great opportunities in the future.
Ultrathin two-dimensional (2D) nanomaterials are important in energy and environmental applications such as electrocatalysis, supercapacitors, solar cells, photocatalysis and lithium-ion batteries. The typical graphene-like ultrathin 2D nanomaterials contain transition metal dichalcogenides, hexagonal boron nitride, graphitic carbon nitride, layered metal oxides, and layered double hydroxides. Promising research further enrich the exploration of 2D ultrathin family members, such as MXenes, metal−organic frameworks, covalent organic frameworks, polymers, black phosphorus, inorganic perovskites, and organic−inorganic hybrid. The goal of this collection is to provide a platform where researchers can showcase the latest innovations on 2D nanomaterials that are applied in the energy and environmental fields. Novel scientific insights into the synthetic strategies, theoretical and experimental investigations on 2D nanomaterials toward energy and environmental applications are highly needed.
The current Research Topic aims to cover promising, recent, and novel research trends on the synthesis of novel 2D nanomaterials and their energy and environmental applications. We welcome submissions of Original Research, Review, Mini Review, Perspective, and Short Communications on this topic. Research themes include, but are not limited to the following:
• Exploration of 2D nanomaterials toward energy applications, such as hydrogen evolution reaction, H2O2 production, CO2 reduction, N2 reduction, O2 reduction fuel cells, storage batteries, supercapacitors, electronic/optoelectronic devices, etc.
• Exploration of 2D nanomaterials toward environmental applications, such as using biological process, adsorption, advanced oxidation processes, photocatalysis, membrane separation for wastewater treatment.
• Preparation of composited nanomaterials by using ultrathin 2D nanomaterials as building blocks toward energy and environmental applications.
• Theoretical investigation of the performance-property relationships in 2D nanomaterials.
• Deep understanding of the mechanisms when 2D nanomaterials are applied in energy fields.
