Single-atom catalysis recently attracts great attentions, however, whether single atom or their nanoparticle (NP) has the advantage in its intrinsic activity remains under heated debate. Ag/Al2O3 is a widely used catalyst for many catalytic reactions, while the effect of Ag particle size on the activity is seldom investigated due to the great difficulty in synthesizing single atom Ag and Ag clusters/particles with different sizes. Herein, we firstly prepared an atomically dispersed Ag/Al2O3 cata...

CsPbI3 perovskite quantum dots (QDs) have great potential in optoelectronic devices due to their suitable band-gaps, but low photoluminescence quantum yields (PLQYs) and poor phase stability seriously impede their practical application. This paper reports the synthesis of Ce3+-doped CsPbI3 QDs by a hot injection method. In the presence of the dopant (Ce3+), the highest PLQY of CsPbI3 QDs reached 99%, i.e., near-unity PLQY, and the photoluminescence (PL) emission of CsPbI3 QDs could be well maint...

Surface characterization of metal nanoparticles is a critical need in nanocatalysis for in-depth understanding of the structure-function relationships. The surface structure of nanoparticles is often different from the subsurface, and it is challenging to separately characterize the surface and the subsurface. In this work, theoretical calculations and extended X-ray absorption fine structure (EXAFS) analysis illustrate that the surface atoms of noble metals (Pt and Pd) are oxidized in the air, ...

Metal chalcogenide solid solution, especially ZnCdS, has been intensively investigated in photocatalytic H2 generation due to their cost-effective synthetic procedure and adjustable band structures. In this work, we report on the defect engineering of ZnCdS with surface disorder layer by simple room temperature Li-ethylenediamine (Li-EDA) treatment. Experimental results confirm the formation of unusual Zn and S dual vacancies, where rich S vacancies (VS) served as electron trapping sites, meanwh...

Despite outstanding accomplishments in catalyst discovery, finding new, more efficient, environmentally neutral, and noble metal-free catalysts remains challenging and unsolved. Recently, complex solid solutions consisting of at least five different elements and often named as high-entropy alloys have emerged as a new class of electrocatalysts for a variety of reactions. The multicomponent combinations of elements facilitate tuning of active sites and catalytic properties. Predicting optimal cat...

Formic acid oxidation (FAO) is a typical anode reaction in fuel cells that can be facilitated by modulating its direct and indirect reaction pathways. Herein, PtAu bimetallic nanoparticles loaded onto Co and N co-doping carbon nanoframes (CoNC NFs) were designed to improve the selectivity of the direct reaction pathway for efficient FAO. Based on these subtle nanomaterials, the influences of elemental composition and carbon-support materials on the two pathways of FAO were investigated in detail...

Electrocatalytic N2 reduction provides an attractive alternative to Haber-Bosch process for artificial NH3 synthesis. The difficulty of suppressing competing proton reduction, however, largely impedes its practical use. Herein, we design a hydrophobic octadecanethiol-modified Fe3P nanoarrays supported on carbon paper (C18@Fe3P/CP) to effectively repel water, concentrate N2, and enhance N2-to-NH3 conversion. Such catalyst achieves an NH3 yield of 1.80 × 10−10 mol·s−1·cm−2 and a high Faradaic effi...

Melanoma is a highly aggressive cancer which often forms metastatic tumors in the lung, leading to sharply reduced patients’ survival rate. Effectively treating these tumors thus could improve late stage melanoma with lung metastasis. In this study, we fabricated a Cys-Arg-Glu-Lys-Ala with N-methylated Glu (CR(NMe)EKA) decorated disk shaped nano vehicle to co-deliver tumor necrosis factor-related apoptosis-inducing ligand (TRAIL) and paclitaxel (PTX) to lung melanoma tumor sites (TRAIL-[ND-PTX]C...

Early cancer diagnosis requires ultrasensitive detection of tumor markers in blood. To this end, we develop a novel microcantilever immunosensor using nanobodies (Nbs) as receptors. As the smallest antibody (Ab) entity comprising an intact antigen-binding site, Nbs achieve dense receptor layers and short distances between antigen-binding regions and sensor surfaces, which significantly elevate the generation and transmission of surface stress. Owing to the inherent thiol group at the C-terminus,...

Photoelectrochemical oxygen reduction reaction (ORR) toward H2O2 is highly desirable because only sunlight, O2 and water are required in the process. However, the corresponding studies are still at its infancy because of the lack of suitable photocathodes, especially inorganic semiconductor photocathodes. In this work, we report CuBi2O4/CuO (CBO/CuO) heterojunction submicrocrystalline film photocathodes with efficient ORR activity for H2O2 production. The heterojunction film photocathodes were p...
