The structure and configuration of reaction centers, which dominantly govern the catalytic behaviors, often undergo dynamic transformations under reaction conditions, yet little is known about how to exploit these features to favor the catalytic functions. Here, we demonstrate a facile light activation strategy over a TiO₂-supported Cu catalyst to regulate the dynamic restructuring of Cu active sites during low-temperature methanol steam reforming. Under illumination, the thermally de

Abstract An efficient water oxidation photocatalyst is imperative for the realization of artificial photosynthesis. Herein, a cooperative strategy is represented that enables 2D structure tailoring and lattice distortion engineering simultaneously over a BiVO 4 photocatalyst for efficient visible‐light‐driven oxygen evolution reaction (OER). Specifically, the lattice distortion engineering is achieved through the introduction of a sodium (Na + ) additive during the ion exchange process. Structur

Abstract Strong coupling between the Si photocathode and a low‐cost cocatalyst is of great significance for enhancing the photoelectrochemical hydrogen evolution. Here, a facile method is proposed to in situ assemble amorphous MoS x (a‐MoS x ) thin‐film onto a single crystal p‐Si through a self‐reduction mechanism to achieve strong coupling. In the process of self‐reduction, the (MoS 4 ) 2− anion is reduced to form a‐MoS x by the oxidation of H–Si to form SiO x , which is etched further to form

The sluggish transfer of electrons from a planar p-type Si (p-Si) semiconductor to a cocatalyst restricts the activity of photoelectrochemical (PEC) hydrogen evolution. To overcome such inefficiency, an elegant interphase of the semiconductor/cocatalyst is generally necessary. Hence, in this work, a NiS₂ /NiS heterojunction (NNH) is prepared in situ and applied to a planar p-Si substrate as a cocatalyst to achieve progressive electron transfer. The NNH/Si photocathode exhibits an onse

The composition of Li-Si alloys in a lithiated single crystal Si(111) was studied using windowless energy dispersive spectroscopy (EDS), scanning electron microscopy (SEM), and soft X-ray emission spectroscopy (SXES). The intensities of Li Kα and Si L2,3 were obtained after deconvolution of the windowless EDS spectra. The Li Kα, Si L2,3, and Si Kα intensity changes along a line scan revealed a clear layered structure with varied Li concentrations. The Li distribution in Li-Si alloys was obtained

As one of the major impurities in the organic electrolyte, HF can react with the alkali components in the solid electrolyte interphase (SEI), such as lithium alkoxide and lithium carbonate, to form more LiF-rich SEI. Here, the effects of HF on the lithiation behavior of the single crystal Si(111) anode were studied using scanning electron microscopy, soft X-ray emission spectroscopy, and windowless energy-dispersive X-ray spectroscopy. When the Li-Si alloy is formed in 1.0 M LiPF₆ in

Solar-driven photoelectrochemical (PEC) water splitting into hydrogen fuel is a promising avenue for renewable energy conversion to overcome energy crises and environmental concerns. Earth-abundant Si semiconductors with excellent light-harvesting capabilities are suitable photocathode candidates for the PEC hydrogen evolution reaction (HER), but suffer from intrinsic instability and sluggish kinetics. Extensive studies have demonstrated that surface/interface engineering can serve as an effecti

Abstract. Wintertime low temperatures and snow cover usually diminish the friction coefficient of asphalt pavements, thereby elevating accident and congestion risks. Road surface temperature (RST) is an important parameter for maintaining traffic safety under extreme winter weather conditions, as it helps predict road icing events. Aiming to enhance the precision and robustness of RST prediction, this paper introduces a forecasting framework combining optimized Long Short-Term Memory (LSTM) arch
