The issues of polysulfide shuttling and lethargic sulfur redox reaction (SROR) kinetics are the toughest obstacles of lithium–sulfur (Li–S) battery. Herein, integrating the merits of increased density of metal sites and synergistic catalytic effect, a unique single‐atom catalyst (SAC) with nonmetallic‐bonding Fe–Mn diatomic pairs anchored on hollow nitrogen‐doped carbonaceous nanodisk (denoted as...
Metallic sodium is regarded as the most potential anode for sodium‐ion batteries due to its high capacity and earth‐abundancy. Nevertheless, uncontrolled Na dendrite growth and infinite volume change remain great challenges for developing high‐performance sodium metal batteries. This work provides a simple and general approach to stabilize sodium metal anode (SMA) by constructing Sn nanoparticles‐anchored...
Sluggish sulfur redox reaction (SROR) kinetics accompanying lithium polysulfides (LiPSs) shuttle effect becomes a stumbling block for commercial application of LiS battery. High‐efficient single atom catalysts (SACs) are desired to improve the SROR conversion capability; however, the sparse active sites as well as partial sites encapsulated in bulk‐phase are fatal to the catalytic performance. Herein,...
Anticancer immunotherapy is hampered by the poor tumor immunogenicity and immunosuppressive tumor microenvironment (TME). Herein, a liposome nanodrug co‐encapsulating doxycycline hydrochloride (Doxy) and chlorin e6 (Ce6) to simultaneously induce autophagy inhibition and mitochondria dysfunction for potentiating tumor photo‐immunotherapy is developed. Under near infrared laser irradiation, Ce6 generates...
Pd‐NO2‐UiO‐66 for DMC Catalysis
In article number 2208238, Ye‐Yan Qin, Yuan‐Gen Yao, and co‐workers first introduce acidity/alkalinity functionalized metal–organic frameworks (MOFs) into dimethyl carbonate (DMC) catalysis, and the Lewis acidic Pd‐NO2‐UiO‐66 exhibits excellent catalytic behavior. In addition to affecting the interaction of Pd(II) and support, the ‐NO2 group has a dominant role in the...
The acid–base properties of supports have an enormous impact on catalytic reactions to regulate the selectivity and activity of supported catalysts. Herein, a train of Pd‐X‐UiO‐66 (X = NO2, NH2, and CH3) catalysts with different acidity/alkalinity functional groups and encapsulated Pd(II) species is first developed, whose activities in dimethyl carbonate (DMC) catalysis are then investigated in...
A universal strategy is established for preparing the carbonaceous matrix‐based atomically distributed metal catalysts M‐BPC (M=Ni, Co, Fe, Cu, and Mn, and biomass‐derived porous carbon (BPC)) by one‐step pyrolysis of mixed metal salts and biomass alfalfa. The optimized Ni‐BPC has dual‐atom Ni(II)2N4(µ2‐N)2 moieties, which are chemically anchored on the alfalfa‐derived developed porous N‐doped carbon...
Immunotherapy brings great benefits for tumor therapy in clinical treatments but encounters the severe challenge of low response rate mainly because of the immunosuppressive tumor microenvironment. Multifunctional nanoplatforms integrating effective drug delivery and medical imaging offer tremendous potential for cancer treatment, which may play a critical role in combinational immunotherapy to overcome...
Combining the features of host templates and guest species is an efficient strategy to optimize the photo/electrocatalytic performance. Herein, novel host–guest thin‐film electrocatalysts are designed and developed with Pt doped carbon (Pt/C) confined into porphyrin‐based metal‐organic frameworks (MOFs). Porous MOF PCN‐222 and PCN‐221 thin films are used as the host templates and fabricated using...
A stomach functional imaging technique based on photoacoustics achieves noninvasive gastric acid secretory assessment utilizing pH‐responsive polyaniline nanoprobes. A testing protocol mimicking clinical practice is established using a mouse model. After imaging, the nanoprobes are excreted outside the body without inducing systematic toxicity. Further optimization and translation of this technology...
