“…It has been almost four decades of pursuits in the solar‐driven photoelectrochemical (PEC) water splitting for efficient hydrogen (H 2 ) production, as a clean fuel without direct production of CO 2 . 2D transition metal dichalcogenides (TMDs), such as MoS 2 , MoSe 2 , and so forth, are always loaded on surface of p‐type doped silicon (p‐Si) photocathode for hydrogen evolution reaction (HER). Generally, the TMDs/Si composite photoelectrodes have advantages of large specific surface areas, low material costs, and highly catalytic activities.…”

“…However, due to the ultrafast transport of photogenerated charge carriers, the produced electrons and holes are easily recombined, thus decreasing the PEC performance of 2D TMDs photoelectrodes for water splitting [102,103]. Therefore, to further improve the PEC activity of 2D TMDs-based photoelectrodes, several nanocarbon co-catalysts have been introduced to boost the separation and transfer of photogenerated charge carriers [104]. For instance, Agnoli and coworkers fabricated a p-n MoS 2 /N-doped cGO heterojunction through an aerosol process in a furnace at 900 °C for enhancing PEC-HER, as shown in Fig.…”

Solar-driven photoelectrochemical (PEC) water splitting systems are highly promising for converting solar energy into clean and sustainable chemical energy. In such PEC systems, an integrated photoelectrode incorporates a light harvester for absorbing solar energy, an interlayer for transporting photogenerated charge carriers, and a co-catalyst for triggering redox reactions. Thus, understanding the correlations between the intrinsic structural properties and functions of the photoelectrodes is crucial. Here we critically examine various 2D layered photoanodes/photocathodes, including graphitic carbon nitrides, transition metal dichalcogenides, layered double hydroxides, layered bismuth oxyhalide nanosheets, and MXenes, combined with advanced nanocarbons (carbon dots, carbon nanotubes, graphene, and graphdiyne) as co-catalysts to assemble integrated photoelectrodes for oxygen evolution/hydrogen evolution reactions. The fundamental principles of PEC water splitting and physicochemical properties of photoelectrodes and the associated catalytic reactions are analyzed. Elaborate strategies for the assembly of 2D photoelectrodes with nanocarbons to enhance the PEC performances are introduced. The mechanisms of interplay of 2D photoelectrodes and nanocarbon co-catalysts are further discussed. The challenges and opportunities in the field are identified to guide future research for maximizing the conversion efficiency of PEC water splitting.

structure was found for the first time in a mineral composed by CaTiO 3 in 1839. Since then, multiple metal oxide perovskites (AMO 3 ) were developed, which have interesting properties for ferroelectric, superconductive, and pyroelectric applications. Metal halide perovskites (X is a halide anion such as Cl − , Br − , or I − ), which were developed later, display promising semiconducting properties. In particular, lead halide perovskites (APbX 3 ) are the most widely studied perovskite composition and are classified according to the A cation into hybrid perovskites (methylammonium bromide, MA or formamidinium, FA) and all-inorganic perovskites (cesium, Cs). [2] The electronic properties of the perovskites are related to the M-X bond, while the size of the A cation can introduce crystal distortion and change the symmetry of the ideal cubic crystal structure. [3] Interestingly, by using a large A organic cation, low-dimensional halide perovskites can be formed, including 2D sheets, 1D chains, or 0D clusters. [4] Lead halide perovskites are revolutionizing photovoltaic technology thank to their outstanding optical and electronic properties, low cost, and simple preparation. Compared to silicon-based technology, perovskites are prepared from more abundant and low-cost precursors. The superior performance and high efficiency of perovskite-based solar cells (PSC) are due to i) high optical absorption coefficient, ii) long carrier diffusion length This article delineates the state of the art for several materials used in the harvest, conversion, and storage of energy, and analyzes the challenges to be overcome in the decade ahead for them to reach the market and benefit society. The materials covered have had a special interest in recent years and include perovskites, materials for batteries and supercapacitors, graphene, and materials for hydrogen production and storage. Looking at the common challenges for these different systems, scientists in basic research should carefully consider commercial requirements when designing new materials. These include cost and ease of synthesis, abundance of precursors, recyclability of spent devices, toxicity, and stability. Improvements in these areas deserve more attention, as they can help bridge the gap for these technologies and facilitate the creation of partnerships between academia and industry. These improvements should be pursued in parallel with the design of novel compositions, nanostructures, and devices, which have led most interest during the past decade. Research groups are encouraged to adopt a cross-disciplinary mindset, which may allow more efficient use of existing knowledge and facilitate breakthrough innovation in both basic and applied research of energy-related materials.
