Abstract With energy shortages and excessive CO 2 emissions driving climate change, converting into high‐value‐added products offers a promising solution for carbon recycling. We investigate reduction reactions (CO RR) catalyzed by 10 single‐atom catalysts (SACs), incorporating weak non‐covalent interactions, specifically lone pair‐π H‐π interactions. The SACs, consisting of transition metals coordinated three atoms in defective graphene substrate (3C‐TM, TM=Sc‐Zn), leverage these interactions to influence the fluctuations intermediates limiting potentials RR, without altering overall reaction pathway. Our findings show that SACs based on early (Sc, Ti, V, Cr) can serve as C 1 products, including HCOOH, HCHO, CH 3 OH, 4 , while those Fe Co are suitable formation. Driving force analysis helps bridge theoretical results with experimental observations propose modified approach assessing hydrogen evolution (HER) competition. Ni Cu exhibit moderate HER tolerance, excel selective reduction. also identify linear scaling relationship between free energies *COOH *CO. This study valuable insights future studies large‐scale computational screenings.

Abstract Copper‐based electrocatalysts are recognized as crucial catalysts for CO 2 electroreduction into multi‐carbon products. However, achieving copper‐based with adjustable valences via one‐step facile synthesis remains a challenge. In this study, Cu/Cu O heterostructure is constructed by adjusting the anion species of Cu ions‐containing electrolyte during electrodeposition synthesis. Then, tuned nanoarchitectures ranging from dendrites to polyhedrons achieved introducing transition metal ions additives, leading an interfacial microenvironment /H adsorption on electrodes. Additionally, polyhedral used templates depositing Ag single atoms (Ag SA ), which known synergistic active sites promoting * COH toward C 2+ The prepared ‐Cu/Cu catalyst evaluated in flow cell and exhibited FE C2+ 90.2% partial current density (jc ) 426.6 mA cm −2 electroreduction. As revealed situ Raman spectra functional theory calculations, introduction slows down reduction + electroreduction, especially at high density.

Photothermal therapy (PTT) is an emerging treatment modality for cancer management. However, the photothermal agents (PTAs) used in PTT should have sufficient biocompatibility, water dispersibility, and good photoresponsive. In this aspect, water-dispersible biocompatible linear polyphosphate (LP)-functionalized CuS nanoparticles (LP-CuS NPs) were developed using sodium tripolyphosphate (LP molecule) as a surface passivating agent. The successful formation of green covellite phase was confirmed by X-ray diffraction TEM analyses, its functionalization with LP ligand evident from photoelectron spectroscopy, Fourier transform infrared, thermogravimetric analysis, light scattering measurements. It has been found that use not only stabilizes crystallographic overcoming requirement soft but also provides long-term aqueous colloidal stability, which essential applications. suspension LP-CuS NPs showed excellent heating efficacy under near infrared (NIR) irradiation (980 nm) strong binding affinity towards anticancer drug, doxorubicin hydrochloride (DOX). drug-loaded systems (DOX@LP-CuS revealed pH-dependent drug release behavior higher concentrations mild acidic environment. vitro studies substantial cellular uptake DOX-loaded cell lines enhanced toxicity them upon NIR through apoptotic induction, suggesting their potential application chemo-photothermal therapy.
