“…X-ray photoelectron spectroscopy (XPS) can confirm the chemical state and composition of 1T-WS 2 and distinguish the different metallic phases of WS 2 . Figure 7C indicates that the WS 2 nanosheets are a mixture of 1T and 2H phases [90,91]. The Tafel plots in Figure 7D were measured in a 0.5 M H 2 SO 4 solution using a typical three-electrode cell setup.…”

Two-dimensional transition-metal dichalcogenides (TMDs) are considered as the next generation of hydrogen evolution electrocatalysts due to their adjustable band gap, near-zero Gibbs free energy, and lower cost compared to noble metal catalysts. However, the electrochemical catalytic hydrogen evolution performance of TMDs with two-dimensional properties is limited by innate sparse catalytic active sites, poor electrical conductivity, and weak electrical contact with the substrate. It remains challenging for the intrinsic activity of TMDs for electrocatalytic and photocatalytic hydrogen evolution reactions (HERs) to compete with the noble metal platinum. In recent years, significant development of transition metal chalcogenides, especially MoS2 and WS2, as catalysts for electrocatalytic and photocatalytic HERs has proceeded drastically. It is indispensable to summarize the research progress in this area. This review summarizes recent research results of electrocatalysts and photocatalysts for hydrogen evolution reactions based on two-dimensional materials, mainly including MoS2, WS2, and their compounds. The challenges and future development directions of two-dimensional hydrogen evolution reaction electrocatalysts and photocatalysts are summarized and prospected as well.

“…In recent years, the rapid development of the social economy has not only improved people’s quality of life but also caused serious energy and environmental problems around the world. − Hydrogen is a kind of green energy carrier, and the combustion product is water without polluting the environment. − Photocatalytic water splitting for hydrogen production is an ideal strategy for the world energy and environmental problems because it can directly convert solar energy into clean and green hydrogen. − The most critical step in this process is the choice of photocatalysts. Over the past decade, a nonmetal semiconductor, carbon nitride, has attained widespread attention .…”

As photocatalysts, holey carbon nitride nanosheets (HCNS) have attracted considerable attention. Although many advances have been made in the preparation of HCNS, challenges remain in the low-cost preparation of HCNS. In this work, a one-step strategy for preparing HCNS was explored. First, melamine was placed in a small ceramic boat, which was in a large ceramic boat. Next, the gap between two ceramic boats was filled with copper oxide. Finally, the two boats were wrapped in tin foil and heat-treated. During the thermal polymerization of melamine, released ammonia is decomposed by copper oxide, and the equilibrium shifts to the right, further accelerating the release of ammonia and achieving the preparation of HCNS. Meanwhile, partial copper oxide is reduced to copper by ammonia. After a simple heat treatment, the copper in the mixture can be converted back to copper oxide and realize recycling. The obtained HCNS displays high looseness and enhanced photogenerated charge carrier separation efficiency. Our results indicate that the filled copper oxide can effectively decompose ammonia, affect the thermal condensation atmosphere, and significantly improve the photocatalytic activity of carbon nitride. This work provides a new idea for further fundamental and applied research of HCNS.
