Sub-nanometer catalysts have drawn great attention based on their superior catalytic activity and extensive application in advanced oxidation processes(AOPs). Nonetheless, the precise regulation of the coordination environment and exploration of the peroxymonosulfate(PMS) activation mechanism remain the focus of ***, we report the preparation of Fe catalysts with diverse sizes, including single atoms(SAs), double atoms(DAs), and nanoparticles(NPs) via adjusting the precursor. Sub-nanometric Fe catalysts exhibit a higher catalytic activity for Bisphenol A(BPA) degradation. It is confirmed that the catalytic activity of the Fe diatomic catalysts(Fe2–N/C) is 2.5 times that of the Fe single-atom catalysts(Fe1–N/C) and 8.3 times that of the Fe-nanoparticleloaded catalysts(FeNP–N/C). Broad pH adaptation ranges and reusability have also been proved. Based on experimental verification and density functional theory, non-free radical pathways dominate the degradation process of BPA, while free radical pathways are in an auxiliary position, accompanied by electron transfer *** is found that the synergistic effect of Fe2–N6sites and pyridinic N adsorption centers contribute to the ultra-high catalytic activity of Fe2–N/C. This work opens up an efficient way for single atom catalysts-based advanced oxidation processes for the efficient removal of refractory organic pollutants.

The search for a novel strategy to sculpt semiconductor nanowires （NWs） at the atomistic scale is crucial for the development of new paradigms in optics, electronics, and spintronics. Thus far, the fabrication of single-crystalline kinked semiconductor NWs has been achieved mainly through the vapor-liquid-solid growth technique. In this study, we developed a new strategy for sculpting single-crystalline kinked wurtzite （WZ） MnSe NWs by triggering the nonpolar axial-oriented growth, thereby switching--at the atomistic scale---the NW growth orientation along the nonpolar axes in a facile solution-based procedure. This presents substantial challenges owing to the dominant polar c axis growth in the solution-based synthesis of one-dimensional WZ nanocrystals. More significantly, the ability to continuously switch the nonpolar axial-growth orientation allowed us to craft the kinking landscape of types 150°, 120°, 90°, and 60°. A probabilistic analysis of kinked MnSe NWs reveals the correlations of the synergy and interplay between these two sets of nonpolar axial growth-orientation switching, which determine the actual kinked motifs. Furthermore, discriminating the side-facet structures of the kinked NWs significantly strengthened the spatially selected interaction of Au nanoparticles. We envisage that such a facile solution-based strategy can be useful for synthesizing other single-crystalline kinked WZ-type transition-metal dichalcogenide NWs to develop novel functional materials with finely tuned properties.

Manipulating the self-assembly of transition metal telluride nanocrystals(NCs) creates opportunities for exploring new properties and device applications. Iron ditelluride(FeTe2) has recently emerged as a new class of magnetic semiconductor with three-dimensional(3D) magnetic ordering and narrow band gap structure, yet the self-assembly of FeTe2 NCs has not been achieved. Herein, the tree-like FeTe2 nanoarchitectures with orthorhombic crystal structure have been successfully synthesized by hot-injection solvent thermal approach using phosphine-free Te precursor. The morphology, size, and crystal structure have been investigated using transmission electron microscopy(TEM), high-resolution TEM(HRTEM),and powder x-ray diffraction(XRD). We study the formation process of tree-like FeTe2 NCs according to trace the change of the sample morphology with the reaction time. It was found that the FeTe2 nanoparticles show oriented aggregation and self-assembly behavior with the increase of reaction time, which is attributed to size-dependent magnetism properties of the samples. The magnetic interaction is thought to be the driving force of nanoparticle self-organization.
