Borophene, a promising material with potential applications in electronics, energy storage, and sensors, is successfully grown as a monolayer on Ag(111), Cu(111), and Au(111) surfaces using molecular beam epitaxy. The growth of two‐dimensional borophene on Ag(111) and Au(111) is proposed to occur via surface adsorption and boron segregation, respectively. However, the growth mode of borophene on Cu(111)...
The rational design of the directional charge transfer channel represents an important strategy to finely tune the charge migration and separation in photocatalytic CO2‐to‐fuel conversion. Despite the progress made in crafting high‐performance photocatalysts, developing elegant photosystems with precisely modulated interfacial charge transfer feature remains a grand challenge. Here, a facile one‐pot...
Slow charge kinetics and unfavorable CO2 adsorption/activation strongly inhibit CO2 photoreduction. In this study, a strain‐engineered Cs3Bi2Br9/hierarchically porous BiVO4 (s‐CBB/HP‐BVO) heterojunction with improved charge separation and tailored CO2 adsorption/activation capability is developed. Density functional theory calculations suggest that the presence of tensile strain in Cs3Bi2Br9 can significantly...
Single atom sites (SAS) of FeN4 are clarified as one of the most active components for the oxygen reduction reaction (ORR). Effective strategies by engineering the local coordination environment and site density of FeN4 sites are crucial to further enhance the electrocatalytic ORR performance. Herein, the integration of a second metal of Mn with Fe to construct Fe&Mn/N‐C catalysts with enhanced...
Nowadays, nearly 48.7% near‐infrared (NIR) irradiation (>800 nm) of the full solar spectrum has actually not been fully utilized since the state‐of‐the‐art perovskite film usually can only absorb the most UV–vis sunlight radiation. Herein, high efficiency integrated Cs0.15FA0.85PbI3 perovskite/organic bulk (PC61BM:D18:Y6) heterojunction solar cells with enhanced low energy photon harvest until...
The practical deployment of promising NiFe‐based oxygen evolution reaction (OER) electrocatalysts is heavily limited due to the constrain in both stability and activity under industrial conditions. Herein, a 3D free‐standing NiFe(oxy)hydroxide‐based electrode with Schottky junction is constructed, in which NiFe(oxy)hydroxide (NiFe(OH)x) nanosheets are chemically assembled on the top of metal‐like...
Exploring the origin of transition metal (TM) lattice‐doped layered double hydroxides (LDHs) toward the oxygen evolution reaction (OER) plays a crucial role in engineering efficient electrocatalysts. Without understanding the physics behind the TM‐induced catalytic enhancements, it would be challenging to design the next generation of electrocatalysts. Herein, single Ru atoms are introduced into a...
Metal–organic frameworks (MOFs) provide intriguing platforms for the design of responsive materials. It is challenging to mobilize as many components as possible of a MOF to collaboratively accomplish multiple responsive properties. Here, reversible photochromism, piezochromism, hydrochromism, ionochromism, and luminescence modulation of an ionic Eu(III) MOF is reported furnished by cationic electron‐deficient...
In article number 1704531, Ye Wang, Yi‐Jun Xu, and co‐workers reveal the double‐edged sword role of graphene on boosted charge separation/transfer versus active site control by constructing a TiO2 nanotube arrays@RGO/MoS2 heterostructure. This finding manifests that an efficient design for a specific photoredox process over graphene‐semiconductor photocatalysts should take both improved charge separation/transfer...
Charge separation/transfer is generally believed to be the most key factor affecting the efficiency of photocatalysis, which however will be counteracted if not taking the active site engineering into account for a specific photoredox reaction. Here, a 3D heterostructure composite is designed consisting of MoS2 nanoplatelets decorated on reduced graphene oxide‐wrapped TiO2 nanotube arrays (TNTAs@RGO/MoS...
Ultraviolet (UV) light can be used in versatile applications ranging from photoelectronic devices to biomedical imaging.

2D transition metal dichalcogenides materials are explored as potential surface‐enhanced Raman spectroscopy substrates. Herein, a systematic study of the Raman enhancement mechanism on distorted 1T (1T′) rhenium disulfide (ReS2) nanosheets is demonstrated. Combined Raman and photoluminescence studies with the introduction of an Al2O3 dielectric layer unambiguously reveal that Raman enhancement on...
Promising semiconductor‐based photocatalysis toward achieving efficient solar‐to‐chemical energy conversion is an ideal strategy in response to the growing worldwide energy crisis, which however is often practically limited by the insufficient photoinduced charge‐carrier separation. Here, a rational cascade engineering of Au nanoparticles (NPs) decorated 2D/2D Bi2WO6–TiO2 (B–T) binanosheets to foster...
