Summary: Nickel sulfide quantum dots@NiFe-terephthalic acid nanosheet (NSQDs@NiFe-TPA) composites were prepared by adjusting the concentration of the sulfurizing agent. The in situ formed NiS/Ni3S2 quantum dots with grain sizes of around 5 nm were evenly dispersed on the surface of NiFe-TPA nanosheets. The as-prepared Ni3S2@NiFe-TPA exhibited excellent HER performance, with an overpotential of only 109 mV to reach a current density of 10 mA cm(-2), and a small attenuation after a 60 h stability test.

Summary: Transition metal oxide electrocatalysts have attracted significant research interest for their unique physicochemical properties. However, they suffer from poor electrocatalytic activity and a limited number of active sites. Heteroatom-doping has emerged as a crucial way to improve conductivity and optimize adsorption, thereby enhancing electrocatalytic activity. Doping, elemental incorporation, and alloying play a significant role in improving overall water splitting performance. This review provides insights into the effect of metal and non-metal doping and highlights the current challenges and future perspectives in the development of high-performance water splitting processes.

Summary: By doping with cobalt atoms, a phase transition from hexagonal-NiSe to rhombohedral-NiSe is induced. The formation of rhombohedral-NiSe reduces the splitting energy and occupancy in the t2g orbits, facilitating the electron transfer process. As a result, the phase-transited catalyst shows satisfying catalytic performance towards oxygen evolution reaction, hydrogen evolution reaction, and overall water splitting.

Summary: Highly efficient electrocatalysts for the oxygen evolution reaction (OER) in neutral electrolytes are crucial for practical water splitting technologies. However, there is a lack of good neutral OER electrocatalysts due to poor stability and slow kinetics at neutral pH. In this study, Ir species nanocluster-anchored, Co/Fe-layered double hydroxide (LDH) nanostructures were developed, which showed enhanced OER kinetics at neutral pH. The optimized OER electrocatalyst demonstrated a low overpotential and high performance when integrated with an organic semiconductor-based photoanode.

Summary: Atomic-scale electrocatalysts for water splitting require adjustments of the supporting structures to anchor and disperse metal single atoms, and their structural properties play a critical role in creating different environments for electrocatalytic activity. The coordination environment to the single-atom active site from the supporting material energetically stabilizes the rate-determining step or intermediate state for hydrogen or oxygen evolution reactions. Increasing the loading amount of metal single atoms maximizes the efficiency and reduces the cost of the electrocatalyst in large-scale practical use. Dual-atom electrocatalysts with different single-atom active sites react with more water molecules and lower the adsorption energy of water by utilizing the difference in electronegativity between the two metal atoms. Single-atom dimers induce asymmetric active sites that promote the degradation of H2O to H-2 or O-2 evolution.

Summary: As silicon-based electronic devices face challenges of material performance decrease and interface quality degradation, ultrathin 2D materials are considered as potential candidates in future electronics due to their atomically flat surfaces and excellent immunity to short-channel effects. By freely stacking and forming high-quality heterostructure interfaces, all-2D electronics based on 2D van der Waals (vdW) interfaces can exhibit more comprehensive functionality and better performance. However, improving the compatibility of 2D material devices with silicon-based industrial technology remains a critical challenge.

Summary: In this study, CsPbBr2I quantum dots (CQDs) with surface modulation were used to fabricate high-detectivity and stable photodetectors. The surface modulation not only passivates defects and inhibits vacancies, but also enhances hole transport capacity by modulating energy level mismatch. The assembled CsPbBr2I photodetectors demonstrated a responsivity of 0.375 A W-1, a detectivity of 1.12 x 10(13) Jones, and an on/off ratio of 10(4). Furthermore, the CsPbBr2I photodetectors exhibited excellent long-term stability for 12 weeks and could withstand 1000 bending cycles. This work provides a guideline for the development of perovskite in wireless optical communication.
