For exploring advanced Zn‐ion batteries (ZIBs) with long lifespan and high Coulombic efficiency (CE), the critically important point is to limit the undesired Zn dendrite and parasitic reactions. Among the coating for electrode is a promising strategy, relying on the trade‐off between its thickness and stability to achieve the ultra‐stable Zn anodes in ZIBs. Herein, a submicron‐thick (≈0.4 µm) zincophilic...
Membrane‐based separation process for unconventional natural gas purification (mainly N2/CH4 separation) has attracted more attention due to its considerable economic benefits. However, the majority of separation membranes at this stage, particularly N2‐selective membranes, achieve the desired separation target by mainly relying on the diffusivity‐selectivity mechanism. To overcome the limitation...
Two‐dimensional low‐melting‐point (LMP) metal nanocrystals are attracting increasing attention with broad and irreplaceable applications due to their unique surface and topological structures. However, the chemical synthesis, especially the fine control over the nucleation (reduction) and growth (crystallization), of such LMP metal nanocrystals remains elusive as limited by the challenges of low standard...
Graphdiyne (GDY) is a fascinating graphene‐like 2D carbon allotrope comprising sp and sp2 hybridized carbon atoms. However, GDY materials synthesized by solution‐phase methods normally come as thick and porous films or amorphous powders with severely disordered stacking modes that obstruct macroscopic applications. Here, a facile and scalable synthesis of ultrathin holey graphdiyne (HGDY) nanosheets...
Enhancing alkaline urea oxidation reaction (UOR) activity is essential to upgrade renewable electrolysis systems. As a core step of UOR, proton‐coupled electron transfer (PCET) determines the overall performance, and accelerating its kinetic remains a challenge. In this work, a newly raised electrocatalyst of NiCoMoCuOxHy with derived multi‐metal co‐doping (oxy)hydroxide species during electrochemical...
Lithium‐ion battery based on LiCrTiO4 (LCTO) is considered to be a promising anode material, as they provide higher safety and durability beyond than that of graphite electrode. However, the applications of this transformative technology demand improved inherent electrical conductivity of LCTO as well as a simple and rapid synthetic route. Here, LCTO with oxygen vacancies (OVs) is fabricated using...
Pore‐structure design with increased ion‐diffusion ability is usually regarded as an effective strategy to improve K‐storage performance in hard carbon (HC). However, the relationship between porous structure and K+ migration behavior remains unclear and requires further exploration. Herein, a series of chemically activated hard carbon spheres (denoted as AHCSs) with controllable micro/mesopores structure...
Infrared Solar Cells
PbS colloidal quantum dot infrared solar cells can supplement silicon or perovskite solar cells. The energy level evolution of large size PbS quantum dots causes the authors to reconsider the matching charge extraction contacts. In article number 2105495, Haisheng Song and co‐workers develop a sputtered ZnO‐based champion device which obtains a certified power conversion efficiency...
Infrared solar cells (IRSCs) can supplement silicon or perovskite SCs to broaden the utilization of the solar spectrum. As an ideal infrared photovoltaic material, PbS colloidal quantum dots (CQDs) with tunable bandgaps can make good use of solar energy, especially the infrared region. However, as the QD size increases, the energy level shrinking and surface facet evolution makes us reconsider the...
Thermal radiation in the mid‐infrared region profoundly affects human lives in various fields, including thermal management, imaging, sensing, camouflage, and thermography. Due to their fixed emissivities, radiance features of conventional materials are usually proportional to the quadruplicate of surface temperature, which set the limit, that one type of material can only present a single thermal...
Solar‐driven evaporation is regarded as a sustainable wastewater treatment strategy for clean water recovery and salt condensation. However, achieving both high evaporation rate and long‐term stability remain challenging due to poor thermal management and rapid salt accumulation and blocking. Here, a T‐shape solar‐driven evaporator, composed of a surface‐carbonized longitudinal wood membrane (C‐L‐wood)...
