Halide perovskites exhibit outstanding optoelectronic properties, which make them an ideal choice for photocatalytic CO2 reduction and benzyl alcohol (BA) oxidation. Nevertheless, the simultaneous realization of the above redox coupling reactions on halide perovskites remains a great challenge, as it requires distinct catalytic sites for different target reactions. Herein, the catalytic sites of Cs...
Molybdenum selenium (MoSe2) has tremendous potential in potassium‐ion batteries (PIBs) due to its large interlayer distance, favorable bandgap, and high theoretical specific capacity. However, the poor conductivity and large K+ insertion/extraction in MoSe2 inevitably leads to sluggish reaction kinetics and poor structural stability. Herein, Coinduced engineering is employed to illuminate high‐conductivity...
Stable platforms of host–guest catalysts are indispensable in the field of heterogeneous catalysis, however, clarifying the specific effect of host remains challenging. Herein, polyoxometalate (POM) is encapsulated in three types of UiO‐66(Zr) with different controlled densities of defects by the aperture opening and closing strategy at ambient‐temperature. It is found that catalytic activity of POM...
Perovskite nanocrystals (PNCs) are promising candidates for solar‐to‐fuel conversions yet exhibit low photocatalytic activities mainly due to serious recombination of photogenerated charge carriers. Constructing heterojunction is regarded as an effective method to promote the separation of charge carriers in PNCs. However, the low interfacial quality and non‐directional charge transfer in heterojunction...
Sodium‐ion batteries (SIBs) are promising alternatives for large‐scale energy storage owing to the rich resource and cost effectiveness. However, there are limitations of suitable low‐cost, high‐rate cathode materials for fast charging and high‐power delivery in grid systems. Herein, a biphasic tunnel/layered 0.80Na0.44MnO2/0.20Na0.70MnO2 (80T/20L) cathode delivering exceptional rate performance through...
The metallic sodium (Na) is characterized by high theoretical specific capacity, low electrode potential and abundant resources, and its advantages manifests itself as a promising candidate anode of sodium metal batteries (SMBs). However, the vaporization during the plating/stripping or uncontrolled growth of sodium dendrites in sodium metal anodes (SMAs) has posed major challenges to its practical...
Electrocatalytic hydrogen evolution is an important approach to produce clean energy, and many electrocatalysts (e.g., platinum) are developed for hydrogen production. However, the electrocatalytic efficiency of commonly used metal catalysts needs to be improved to compensate their high cost. Herein, the electrocatalytic efficiency of platinum nanoparticles (PtNPs) in hydrogen evolution is largely...
Photoimmunotherapy is attractive for cancer treatment due to its spatial controllability and sustained responses. This work presents a ferrocene‐containing Ir(III) photosensitizer (IrFc1) that can bind with transferrin and be transported into triple‐negative breast cancer (TNBC) cells via a transferrin receptor‐mediated pathway. When the ferrocene in IrFc1 is oxidized by reactive oxygen species, its...
The properties of separators significantly affect the efficiency, stability, and safety of the lithium‐based batteries. Therefore, the improvement of the separator material is critical. Polyetherketone (PEK) has excellent general properties, such as mechanical strength, chemical stability, and thermal stability. Thus, it is expected to be an optimal separator material. However, its low solubility‐induced...
The regulation of perovskite crystallization and nanostructure have revolutionized the development of high‐performance perovskite solar cells (PSCs) in recent years. Yet the problem of stably passivating perovskite surface defects remains perplexing. The 1D perovskites possess superior physical properties compared with bulk crystals, such as excellent moisture stability, self‐healing property, and...
Nanomaterial‐based pancreatic cancer treatment has received widespread attention and rapid development in the past few years. The major challenges include the poor combination of diagnosis and therapy, the difficulty in targeting therapy from the root and the unsatisfactory antitumor efficiency, which is accompanied by a great risk of relapse and metastasis. In this work, a positively charged lipid...
The development of materials with efficient heat dissipation capability has become essential for next‐generation integrated electronics and flexible smart devices. Here, a 3D hybridized carbon film with graphene nanowrinkles and microhinge structures by a simple solution dip‐coating technique using graphene oxide (GO) on polyimide (PI) skeletons, followed by high‐temperature annealing, is constructed...
Improved conductivity and suppressed dissolution of lithium polysulfides is highly desirable for high‐performance lithium‐sulfur (Li‐S) batteries. Herein, by a facile solvent method followed by nitridation with NH3, a 2D nitrogen‐doped carbon structure is designed with homogeneously embedded Co4N nanoparticles derived from metal organic framework (MOF), grown on the carbon cloth (MOF‐Co4N). Experimental...
Hepatocellular carcinoma (HCC) is one of the leading causes of cancer‐associated deaths worldwide. There is a lack of efficient therapy for HCC; the only available first‐line systemic drug, sorafenib, can merely improve the average survival by two months. Among the efforts to develop an efficient therapy for HCC, nanomedicine has drawn the most attention, owing to its unique features such as high...
Photothermal conversion ability (PCA) and cell internalization ability (CIA) are two key factors for determining the performance of photothermal agents. The previous studies mostly focus on improving the PCA by exploring new photothermal nanomaterials. Herein, the authors take the hybrids of graphene and gold nanostar (GGN) as an example to investigate the gradually enhanced phototherapy effect by...
