We report a facile strategy for synthesizing uniform heterometallic bi/tri-atom clusters starting from mono-metallic atoms in the liquid phase. Specifically, PtCu bi/tri-atoms are prepared by reducing CuCl at preformed Pt atoms with ethanol inside a PDMS-PEG protective layer. The metal atoms in the PtCu clusters are in reduced chemical states.

Selective oxidation of benzylic C(sp)-H bonds to ketones is critical to the production of fine chemicals but typically requires toxic/precious metal catalysts under harsh conditions. While iron-based complexes have recently served as catalysts for photocatalytic C-H bond activation, most systems operate via homogeneous catalysis. Developing a light-driven strategy under visible light with O as an oxidant is of major importance.

Accelerating the rate-limiting surface Fe(III)/Fe(II) redox cycling is pivotal for efficient iron-mediated Fenton-like decontamination, yet conventional reductants (e.g., toxic hydroxylamine, thiosulfate) suffer from secondary toxicity, self-quenching, and heavy metal leaching.

Developing single-atom catalysts (SACs) with dense active sites and universal synthesis strategies remains a critical challenge. Herein, we present a scalable and universal strategy to synthesize high-density transition metal single-atom sites, anchored in nitrogen-doped porous carbon (M-SA@NC, M = Fe, Co, Ni) and investigate their oxygen reduction reaction (ORR) catalytic activity for flexible Zn-air batteries (ZABs). Using a facile coordination-pyrolysis strategy, atomically dispersed M-N sites with high metal loading are achieved.

Current colorimetric sensing arrays for antioxidant detection often struggle with discrimination due to cross-reactive signals from individual nanozymes. These signals are typically modulated by external factors such as pH or chromogenic substrates, offering limited kinetic and mechanistic diversity. To overcome this, we present a novel triple-channel colorimetric sensing array utilizing two distinct single-atom nanozymes (Cu SA and Fe SA) and one dual-atom nanozyme (CuFe DA).

Volatile organic compounds (VOCs) significantly impact air quality as photochemical smog precursors and health hazards. Catalytic oxidation is a leading VOC abatement method but suffers from catalyst deactivation due to metal sintering and competitive adsorption in complex mixtures. Strong metal-support interactions (SMSIs) provide atomic level control of interfacial electronic and geometric structures.
