Summary: For human safety, efficient removal of formaldehyde in indoor environments is crucial. A metal-organic framework-based single-atom iron catalyst (Fe-SA) is proposed as a potential catalyst for formaldehyde oxidation. Through density functional theory (DFT) calculation, the adsorption characteristic and reaction path of Fe-SA with different coordination environments were explored. Fe-SA with 5-nitrogen coordination (Fe-SA-N-5-C) was selected and tested, showing a formaldehyde removal efficiency of 85.8% at 25 degrees C and 75% relative humidity, surpassing current data. Moisture was found to enhance catalytic oxidation of formaldehyde, indicating the practical applicability and stability of Fe-SA-N-5-C.

Summary: In this study, PdCu nanoparticles were encapsulated into a sulfonate functionalized metal-organic framework, UiO-66-SO3H, and their microenvironment was further modified by coating a hydrophobic polydimethylsiloxane (PDMS) layer. The resulting PdCu@UiO-S@PDMS catalyst exhibited high activity towards electrochemical nitrogen reduction reaction (NRR), surpassing other counterparts. Experimental and theoretical results revealed that the protonated and hydrophobic microenvironment provided protons for NRR and suppressed the competitive hydrogen evolution reaction, while the electron-rich PdCu sites favored the formation of the N2H* intermediate and reduced the energy barrier of NRR, contributing to its excellent performance.

Summary: The coordination environment around single Co sites in a UiO-type metal-organic framework is modulated to synthesize UiO-Co-N-x (x = 2, 3, and 4) catalysts for photocatalytic CO2 reduction. It is found that the photocatalytic performance is strongly influenced by the coordinated N atom number, with UiO-Co-N-3 exhibiting the highest activity. Photo-/electrochemical results confirm the fastest charge transfer kinetics between the photosensitizer and UiO-Co-N-3. Theoretical calculations and in situ diffuse reflectance infrared Fourier transform spectra reveal that UiO-Co-N-3 has the lowest energy barriers for the rate-determining step and desorption energy of CO* among all UiO-Co-N-x samples.

Summary: In this study, the catalytic activity of single-atom cobalt catalysts for the oxidation of NO and Hg0 was improved by doping different p-block elements to regulate the coordination environment. The adsorption energy of O2 and O was calculated to analyze the catalytic activity performance, and four potentially high-activity catalysts were identified. Microkinetic modeling was used to calculate the turnover frequency (TOF) of these catalysts, and the results showed that adjusting the coordination environment of the active metal center significantly improved the catalytic activity of single-atom catalysts in the oxidation of NO and Hg0.

Summary: In this study, the combination of single-atom catalysts and H2O2 as an oxidant is proposed for the catalytic oxidation of nitrogen oxide (NO). The reaction pathways for NO oxidation using H2O2 were determined through theoretical calculations and modeling, with *OOH identified as the most favorable pathway with the highest reaction rate and *HNO3 as the main oxidation product. Compared to conventional oxidants and catalysts, using H2O2 on Fe-N-4-C catalyst lowers the reaction energy barriers and enables the deep oxidation of NO. This research provides valuable insights for the development of materials for NO removal.

Summary: The electrocatalytic bridge-site poisoning of dual-atom catalysts (DACs) has recently gained attention. Surface Pourbaix analysis revealed that the electrochemistry-induced surface coverages of DACs changed significantly with the intermetal distance. The intermetal distance was found to have a pronounced effect on the electrochemical potential window and the type of pre-covered adsorbate, providing a means to tune the electrocatalytic function of DACs.

Summary: This study investigated the reaction pathways of NO oxidation with OH radicals over eight types of single-atom catalysts (SACs) through spin-polarized density functional theory calculations. Fe-N4-C was found to have the highest reaction rate among the SACs studied, indicating its potential for efficient catalytic oxidation of NO at room temperature. The catalytic activity of NO oxidation using OH radicals was found to be higher than that using O2 for the SACs system, as demonstrated by the catalytic reactions plotted on the unified volcano map.
