Precise morphology design and electronic structure regulation are critically significant to promote catalytic activity and stability for electrochemical hydrogen production at high current density. Herein, the carbon nanotube (CNT) encapsulated Fe‐doped NiCoP nanoparticles is in‐situ grown in hierarchical carbonized wood (NCF0.5P@CNT/CW) for water splitting. Coupling merits of porous carbonized wood...
Aqueous Zn‐ion batteries are the ideal candidate for large‐scale energy storage systems owing to their high safety and low cost. However, the uncontrolled deposition and parasitic reaction of Zn metal anode hinder their commercial application. Here, the 2D metal‐organic‐framework (MOF) nanoflakes covered on the surface of Zn are proposed to enable dendrite‐free for long lifespan Zn metal batteries...
Carbon Dioxide Reduction
In article number 2304808, Shijie Yuan, Xiaohu Dai, and co‐workers present a one‐step in situ synthesis of metal–organic framework (MOF)‐on‐MOF catalyst to bring HCO3‐ into the CO2RR reaction using structural reorganization. The authors investigate the reaction mechanism and catalytic response of the MOF‐on‐MOF structure, and propose a CO2RR dual‐channel hypothesis.
The synthesis of efficient and highly selective catalysts and rational reactor design play decisive roles in the industrial application of the electrocatalytic carbon dioxide reduction reaction (CO2RR). In this study, a dual‐metal–organic framework (MOF) copper‐based catalytic electrode is designed and prepared in one step by in situ synthesis on a foamed copper substrate. The MOF‐on‐MOF structure...
Glioblastoma (GBM), the most aggressive and lethal form of malignant brain tumor, is a therapeutic challenge due to the drug filtration capabilities of the blood‐brain barrier (BBB). Interestingly, glioblastoma tends to resist apoptosis during chemotherapy, but is susceptible to ferroptosis. Developing therapies that can effectively target glioblastoma by crossing the BBB and evoke ferroptosis are,...
Breaking immunosuppressive tumor microenvironment (TME) has unique effects on inhibiting tumor growth and recurrence. Here, an endoplasmic reticulum (ER) targeted PdPtCu nanozyme (PNBCTER) is prepared to boost immunotherapy. First, PNBCTER has three kinds of enzyme activities, including catalase (CAT), glutathione oxidase (GSHOx), and peroxidase (POD)‐like activities, which can reshape the TME. Second,...
Gossypol is a chemotherapeutic drug that can inhibit the anti‐apoptotic protein Bcl‐2, but the existing gossypol‐related nanocarriers cannot well solve the problem of chemotherapy resistance. Based on the observation that gossypol becomes black upon Fe3+ coordination, it is hypothesized that encasing gossypol in glyceryl monooleate (GMO) and making it coordinate cobalt ferrite will not only improve...
Lithium‐sulfur batteries (LSBs) are recognized as the prospective candidate in next‐generation energy storage devices due to their gratifying theoretical energy density. Nonetheless, they still face the challenges of the practical application including low utilization of sulfur and poor cycling life derived from shuttle effect of lithium polysulfides (LiPSs). Herein, a hollow polyhedron with heterogeneous...
Water Splitting
In article number 2208270, Lei Li, Li Song, and co‐workers provide a combined strategies of P‐Se binary vacancies and heterostructures to improve the hydrogen evolution performance of MoP/MoSe2‐H electrocatalysts, which present ultra‐low overpotential and is comparable to commercial Pt/C. A more efficient, safer and cheaper Zn‐H2O battery with MoP/MoSe2‐H as cathode is fabricated for...
It is not enough to develop an ideal hydrogen evolution reaction (HER) electrocatalysts by single strategy. Here, the HER performances are significantly improved by the combined strategies of P and Se binary vacancies and heterostructure engineering, which is rarely explored and remain unclear. As a result, the overpotentials of MoP/MoSe2‐H heterostructures rich in P and Se binary vacancies are 47...
High‐concentrated non‐flammable electrolytes (HCNFE) in lithium metal batteries prevent thermal runaway accidents, but the microstructure of their solid electrolyte interphase (SEI) remains largely unexplored, due to the lack of direct imaging tools. Herein, cryo‐HRTEM is applied to directly visualize the native state of SEI at the atomic scale. In HCNFE, SEI has a uniform laminated crystalline‐amorphous...
High operating temperature (HOT) broadband photodetectors are urgently necessary for extreme condition applications in infrared‐guided missiles, infrared night vision, fire safety imaging, and space exploration sensing. However, conventional photodetectors show dramatic carrier mobility decreases and carrier losses with low photoresponsivity at HOT due to the increased carrier scattering in channels...
Broadband Photodetectors
In article number 2206590, Zemin Zhang, Junru Wang, Qingliang Feng, and co‐workers present large‐area Schottky junction of BP/PtSe2 films‐based nano‐device arrays towards high operating temperature broadband photodetection from 532 to 2200 nm at 470 K via a depletion enhanced photocarrier dynamics strategy. The photodetectors show a state‐of‐the‐art operating temperature up...

In article 2300849, Lei Li, Joseph S. Francisco, Meng Gu, and co‐workers uncover a uniform laminated crystalline‐amorphous structure of the solid electrolyte interphase (SEI) at the atomic scale in high‐concentrated non‐flammable electrolytes using cryo‐high‐resolution transmission electron microscopy (HRTEM). This research yields valuable insights into...
Li/CFx battery is one of the most promising lithium primary batteries (LPBs) which yields the highest energy density but with poor rate capability. This Achilles'’ heel hinders the large‐scale applications of Li/CFx batteries. This work first reports a facile chemical modification method of CFx with δ‐MnO2. Having benefited from the chemical bonding, the electrochemical performance at high‐rate discharge...
Durable glioblastoma multiforme (GBM) management requires long‐term chemotherapy after surgery to eliminate remaining cancerous tissues. Among chemotherapeutics, temozolomide is considered as the first‐line drug for GBM therapy, but the treatment outcome is not satisfactory. Notably, regorafenib, an oral multi‐kinase inhibitor, has been reported to exert a markedly superior effect on GBM suppression...
Chemo‐phototherapy has emerged as a promising approach to complement traditional cancer treatment and enhance therapeutic effects. However, it still faces the challenges of drug efflux transporter‐mediated chemoresistance and heat shock proteins (HSPs)‐mediated phototherapy tolerance, which both depend on an excessive supply of adenosine triphosphate. Therefore, manipulating energy metabolism to impair...
2D materials are now at the forefront of state‐of‐the‐art nanotechnologies due to their fascinating properties and unique structures. As expected, low‐cost, high‐volume, and high‐quality 2D materials play an important role in the applications of flexible devices. Although considerable progress has been achieved in the integration of a series of novel 2D materials beyond graphene into flexible devices,...
Literature reports have shown that in primary structures, single‐atom catalysts exhibit better performance than cluster and nanoparticles due to their maximum atom utilization and the fine‐tuning of the electronic structure of the active sites. Hierarchical structures have recently been extensively studied because of increased active sites and orderliness of channels significantly improves the catalytic...
Aqueous zinc‐ion batteries are a low‐cost and safe energy storage system, but suffer from detrimental side reactions and Zn dendrites due to the strong interactions between Zn2+ and water molecules in the electrolytes, and random Zn2+ deposition on the anode surface. Here, an electrolyte involving a dual‐functional additive of polyethylene glycol (PEG) to bypass these issues is reported. The electrolyte...
