2D materials, such as graphene, transition metal dichalcogenides, black phosphorus, layered double hydroxides, and MXene, have exhibited broad application prospects in electrochemical energy conversion due to their unique structures and electronic properties. Recently, the engineering of heterostructures based on 2D materials, including 2D/0D, 2D/1D, 2D/2D, and 2D/3D, has shown the potential to produce synergistic and heterointerface effects, overcoming the inherent restrictions of 2D materials and thus elevating the electrocatalytic performance to the next level. In this review, recent studies are systematically summarized on heterostructures based on 2D materials for advanced electrochemical energy conversion, including water splitting, CO reduction reaction, N reduction reaction, etc. Additionally, preparation methods are introduced and novel properties of various types of heterostructures based on 2D materials are discussed. Furthermore, the reaction principles and intrinsic mechanisms behind the excellent performance of these heterostructures are evaluated. Finally, insights are provided into the challenges and perspectives regarding the future engineering of heterostructures based on 2D materials for further advancements in electrochemical energy conversion.

Proton transfer plays an important role in both hydrogen and oxygen evolution reactions during electrocatalytic water splitting to produce green hydrogen. However, directly adapting the conventional proton/deuterium kinetic isotope effect to study proton transfer in heterogeneous electrocatalytic processes is challenging. Here we propose using the shift in the Tafel slope between protic and deuteric electrolytes, or the Tafel slope isotope effect, as an effective probe of proton transfer characteristics.

The oxygen evolution reaction (OER) in conventional zinc-air batteries (ZABs) involves a complex multielectron transfer process, leading to slow reaction kinetics, high charging voltage, and low energy efficiency. To address these limitations, a zinc-ethanol/air battery (ZEAB) system that strategically replaces the OER with the ethanol oxidation reaction (EOR) possessing a lower thermodynamic potential has been proposed. Herein, a bimetallic catalyst CuCo-embedded nitrogen-doped carbon (CuCo-20%-1), derived from a Cu/Co/Cd co-coordinated metal-organic precursor, is synthesized and exhibits an excellent performance for both EOR and ORR.

Li/CF primary batteries are renowned for their exceptional energy density, yet their practical deployment is hindered by the inherently sluggish kinetics of the CF cathode. This study addresses this limitation by incorporating selenium (Se) into CF (denoted as CF/Se) via a facile low-temperature thermal treatment, significantly enhancing its electrochemical performance. Comprehensive spectroscopic and electrochemical analyses reveal that Se doping induces the formation of CSe bonds, which promote semi-ionic CF bonding, thereby accelerating Li diffusion and reducing charge transfer resistance.

The rapid increase in population has driven the demand for fossil fuel energy, contributing to increased carbon emissions that ultimately accelerate global warming and climate change. Battery storage systems have many advantages over conventional energy sources. However, they face limitations such as energy storage, cost, and environmental hazards that come with the use of chemical binders.

The movement of molecules across the membranous barriers of a cell is fundamental to cellular homeostasis in every living organism. This vital process is facilitated through a mechanistically diverse class of proteins, collectively known as membrane transporters. Among these are so-called carrier proteins that can function in passive and active transport mechanisms.
