Abstract Many existing research focuses on the differences or performance comparisons between single‐atom small‐sized nanocluster catalysts, but there is a lack of comprehensive coupling relationship structure and activity mechanism synergy. This study investigates combined catalytic potential cobalt single atoms (SAs) nanoclusters (NCs) for enhanced peroxymonosulfate (PMS) activation to degrade norfloxacin (NFX). A novel Co SAs‐NCs /CN/TiO 2 catalyst synthesized, featuring SAs NCs uniformly dispersed carbon film wrapping TiO , degradation efficiency NFX solution almost completely degraded, with mineralization rate 76.35%. Density functional theory (DFT) calculations indicate that synergistic interaction promotes more efficient PMS adsorption significantly reduces energy barrier, which enhances electron transfer increases reactive oxygen species (ROS) generation. highlights robust versatile nature this system in addressing various contaminants. elucidates providing new ideas advanced oxidation processes (AOPs) environmental remediation, linking emphasizes practicality importance effectively long‐term remediation water pollutants.

Abstract Single‐atom catalysts (SACs) have rapidly become a hot topic in photocatalytic research due to their unique physical and chemical properties, high activity, selectivity. Among many semiconductor carriers, the special structure of carbon nitride (C 3 N 4 ) perfectly meets substrate requirements for stabilizing SACs; they can also compensate defects C materials by modifying energy bands electronic structures. Therefore, developing advanced ‐based SACs is great significance. In this review, we focus on elucidating efficient preparation strategies burgeoning applications SACs. We outline prospective enhancing performance future.

Indium–palladium intermetallic catalysts have shown great potential for CO2 hydrogenation to methanol. A deep understanding of the synergistic relationship between various components is key developing efficient indium–palladium catalysts. Here, we rationally designed a series with In–Pd ratios and found that InPd(2:1)/m-ZrO2 demonstrated highest reactivity (5.1 mmol/gcat/h), maintaining this performance even after 70 h stability testing at 270 °C 4 MPa. This impressive attributed formation stable compound chemical formula In3Pd2 which close In2O3 phase during reduction process. In situ diffuse reflectance infrared Fourier transform spectroscopy (DRIFTS) density functional theory (DFT) calculations were further conducted confirm formate path more favorable Adsorption energy reactants determine roles In2O3: tends adsorb activate CO2, while has an advantage dissociation H2, could compensate insufficient ability In2O3, thereby promoting reaction intermediates.
