The rational design of inexpensive metal electrocatalysts with exciting catalytic activity for overall water splitting (OWS) remains a significant challenge. Heterostructures of NiFe layered double hydroxides (NiFe‐LDHs) with abundant oxygen defects and tunable electronic properties have garnered considerable attention. Here, a self‐supporting heterostructured catalyst (named MoO3/NiFe‐NF) is synthesized...
With the rapid development of high‐power electronic instruments and communication technology, efficient electromagnetic shielding materials with strong absorption of electromagnetic waves and low reflection characteristics have become the focus of the world's attention. This study designs and synthesizes N‐doped carbon‐coated hollow Fe3O4 nanospheres (Fe3O4@NC) by spraying Ag nanowires (AgNWs) on...
Designing photocatalysts with efficient charge transport and abundant active sites for photocatalytic CO2 reduction in pure water is considered a potential approach. Herein, a nickel‐phthalocyanine containing Ni–N4 active sites‐based conjugated microporous polymer (NiPc‐CMP), offering highly dispersed metal active sites, satisfactory CO2 adsorption capability, and excellent light harvesting properties,...
The synthesis of large‐scale 2D conductive metal‐organic framework films with tunable thickness is highly desirable but challenging. In this study, an Interface Confinement Self‐Assembly Pulling (ICSP) method for in situ synthesis of 4‐in. Ni‐BHT film on the substrate surface is developed. By modulating the thickness of the confined space, the thickness of Ni‐BHT films could be easily varied from...
Perovskite oxides stand out as emerging oxygen evolution reaction (OER) catalysts on account of their effective electrocatalytic performance and low costs. Nevertheless, perovskite oxides suffer from severe bubble overpotential and inhibited electrochemical performance in large current densities due to their small specific surface areas and structural compactness. Herein, the study highlights the...
Developing efficient and stable electrocatalysts for hydrogen evolution reaction (HER) over a wide pH range and industrial large‐scale hydrogen production is critical and challenging. Here, a tailoring strategy is developed to fabricate an outstanding HER catalyst in both acidic and alkaline electrolytes containing high‐density atomically dispersed Ru sites anchored in the CoP nanoparticles supported...
Nanomedicines confront various complicated physiological barriers limiting the accumulation and deep penetration in the tumor microenvironment, which seriously restricts the efficacy of antitumor therapy. Self‐propelled nanocarriers assembled with kinetic engines can translate external energy into orientated motion for tumor penetration. However, achieving a stable ultrafast permeability at the tumor...
The fiber‐shaped aqueous battery (FSAB) has the advantages of flexibility, portability and safety making it promising for energy storage applications. In particular, FSABs based on metal wire current collectors with good electrical conductivity can provide excellent energy storage properties. However, the low adhesion caused by the smooth surface of the metal wire and the unavailability of many electrochemically...
Aqueous alkaline rechargeable nickel‐zinc (Ni–Zn) batteries possess great potential for large‐scale energy storage systems because of their high output voltage, cheap cost, and intrinsic safety. However, the practical applicability of Ni–Zn batteries has been limited by traditional Ni‐based cathodes with low capacity and poor cycle stability. Rational design of electrode structure and composition...
Limited permeability in solid tumors significantly restricts the anticancer efficacy of nanomedicines. Light‐driven nanomotors powered by photothermal converting engines are appealing carriers for directional drug delivery and simultaneous phototherapy. Nowadays, it is still a great challenge to construct metal‐free photothermal nanomotors for a programmable anticancer treatment. Herein, one kind...
The aqueous alkaline rechargeable batteries (AARBs) have an attractive potential for electrochemical energy storage devices. In view of the advantages of high theoretical capacity and desirable negative operating window, bismuth (Bi) has been deemed as a hopeful anode material for AARBs. Unfortunately, intensive reported works of Bi anode are still confronted with limited capacity and poor cycling...
Overproduced hydrogen sulfide (H2S) is of vital importance for the progress of colon cancer and promotes cancer cellular proliferation. Devising pharmacological nanomaterials for tumor‐specific H2S activation will be significant for precise colon cancer treatment. Herein, a biocompatible fusiform iron oxide‐hydroxide nanospindles (FeOOH NSs) nanosystem for magnetic resonance imaging (MRI), ferroptosis,...
In article number 1800785, Guobin Wang, Shuai Wang, Zheng Wang, Lin Wang, and co‐workers fabricate a versatile nanoplatform composed of gold‐nanodot‐decorated hollow carbon nanospheres with hyaluronic acid coating (AuHCNs‐HA). Such a nanoplatform serves as a trimodal drug delivery and therapeutic system. Using this system, their work reveals that weak photothermal effects and weak photodynamic effects...
Despite the therapeutic usefulness of near‐infrared irradiation (NIR)‐induced potent photothermal effects (PTE) and photodynamic effects (PDE), they inevitably damage normal tissues, often posing threat to life when treating tumors adjacent to key organs or major blood vessels. In this study, the frequently overlooked, “weak” PTE and PDE (no killing capability) are employed to synergize chemotherapy...
