Hydrogen and oxygen evolution reactions (HER OER) are important for many electrochemical systems. Besides traditional noble-metal-based catalysts, carbon-based materials have been found to be effective catalyzing these reactions. Various carbon structures doped with heteroatoms (N, S, P, B, transition metals) graphitic-layer-encapsulated metal compound particles shown good activities toward HER OER at universal pHs. In this Perspective, recent research on the development of electrocatalysts...
Nitrogen-coordinated single-metal-atom catalysts (Me–N–C) are promising candidates for CO2-to-CO electrocatalytic conversion. The nature of real active sites in this type electrocatalyst, however, is not clear. In Letter, we study the specific interactions between reaction intermediates and a model single-iron-atom catalyst (Fe–N–C) by combining situ infrared absorption spectroscopy density functional theory (DFT) calculations. For first time, confirm that Fe centers Fe–N4 moieties hosted...
Hypoxia in a solid tumor microenvironment (TME) can lead to the overexpression of hypoxia-inducible factor-1α (HIF-1α), which correlates metastasis. Reactive oxygen species (ROS) induced cell apoptosis is becoming promising method treatment. Currently, ROS generating systems, e.g., photodynamic treatment and sonodynamic treatment, highly depend on (O2) (TME). However, level O2 TME too low produce enough ROS. Herein, we developed an ultrasmall DSPE-PEG2000 coated barium titanate nanoparticle...
Tumor immunotherapy based on immune checkpoint blockade (ICB) still suffers from low host response rate and non-specific distribution of inhibitors, greatly compromising the therapeutic efficiency. Herein, cellular membrane stably expressing matrix metallopeptidase 2 (MMP2)-activated PD-L1 blockades is engineered to coat ultrasmall barium titanate (BTO) nanoparticle for overcoming immunosuppressive microenvironment tumors. The resulting M@BTO NPs can significantly promote BTO's tumor...
Simultaneous promotion of N2 adsorption and NH3 desorption, which is referred to as breaking the scaling relationship, a major challenge in photocatalytic ammonia synthesis reaction. Herein, we have successfully developed an active hydrogen (H*)-switchable dynamic oxygen vacancy (OV) evolution strategy for solving this problem on MoO3–x decorated by Ru nanoparticles (Ru/MoO3–x). In strategy, H* drives cyclic OVs between initial state Ru/MoO3–x intermediate Ru/MoO3–xNy, exhibit strong...
A portable paper-like plasmonic device consisting of a microporous membrane and indium nanoparticles (In NP/MPM) is fabricated through simple thermal evaporation method, which can effectively enhance solar water by floating on the surface.
The proposed mechanism of photocatalytic reaction using a MoC-QDs/C/ZIS composite under visible light irradiation.
Ultrathin Bi<sub>12</sub>O<sub>17</sub>Cl<sub>2</sub> nanosheets, with the thickness of 3–4 nm, were prepared by photo-assisted Ag exfoliation method.
Unlike single-step reactions, multi-step reactions can be greatly facilitated only if all the intermediate catalyzed simultaneously and progressively. Herein, theoretical analysis experiments to illustrate superiority of cascade oxygen evolution reaction (OER) are conducted. As different OER demand Fex Ni1-x OOH with altered Fe/Ni ratios, gradient Fe-doped NiOOH an ideal electrocatalyst for efficient in line. Fine controlling nucleation sequence iron nickel sulfides leads a FeS2 @NiS2...
Core–shell structure is a promising alternative to solid platinum (Pt) nanoparticles as electrocatalyst for oxygen reduction reaction (ORR) in proton exchange membrane fuel cells (PEMFCs). A simple method of preparing palladium (Pd)–platinum core–shell catalysts (Pd@Pt/C) gram-batch was developed with the assistance citric acid. The Pt shell deposition involves three different pathways: galvanic displacement between Pd atoms and cations, chemical by acid, negative charges on surfaces....
The aim of this study was to develop an effective carbonaceous solid acid for synthesizing green fuel additive through esterification lignocellulose-derived levulinic (LA) and n-butanol. Two different sulfonated carbons were prepared from glucose-derived amorphous carbon (GC400) commercial active (AC400). They contrastively studied by a series characterizations (N2 adsorption, X-ray diffraction, elemental analysis, transmission electron microscopy, Fourier transform infrared spectroscopy NH3...
In recent years, antibacterial surface modification of titanium (Ti) implants has been widely studied in preventing implant-associated infection for dental and orthopedic applications. The purpose this study was to prepare a composite coating on porous prevention inducing mineralization, which initialized by deposition poly-l-lysine (PLL)/sodium alginate(SA)/PLL self-assembled coating, followed dopamine deposition, finally situ reduction silver nanoparticles (AgNPs) dopamine. zeta potential,...
Trastuzumab combined with chemotherapy is the first-line treatment for advanced HER2-positive gastric cancer, but it still suffers from limited therapeutic efficiency and serious side effects, which are usually due to poor delivery drug resistance of tumor cells chemotherapeutic drugs. Herein, a type ultrasound microbubble simultaneous sonosensitizers antibodies achieve targeting combination sonodynamic therapy antibody cancer was constructed pyropheophorbide-lipid followed by trastuzumab...
Compared with traditional electrowetting-on-dielectric (EWOD), orbital EWOD is a newly observed droplet manipulation phenomenon on superhydrophobic surface, which has the advantages of high speed, antigravity, and no pollution broad application prospects. However, current research electrowetting structured electrodes focuses statistical characteristics collection, movement process single droplets still unclear. The study eccentric correction helps us to better understand influence local...
