Abstract Single‐atom materials (SAMs) have become one of the most important power sources to push field energy conversion forward. Among main types energy, including thermal electrical solar and biomass SAMs realized ultra‐high efficiency show an appealing future in practical application. More than high activity, uniform active sites also provide a convincible model for chemists design comprehend mechanism behind phenomenon. Therefore, we presented insightful review application single‐atom material conversion. The challenges (e.g., accurate synthesis application) directions machine learning efficient design) applications are included, aiming guidance research next step.

Advancing the performance of Cu-catalyzed electrochemical CO2 reduction reaction (CO2 RR) is crucial for its practical applications. Still, wettable pristine Cu surface often suffers from low exposure to , reducing Faradaic efficiencies (FEs) and current densities multi-carbon (C2+ ) products. Recent studies have proposed that increasing availability by cation-exchange ionomers can enhance C2+ product formation rates. However, due rapid consumption *CO, such promotion in kinetics shorten residence *CO whose adsorption determines selectivity, thus resulting FEs remain low. Herein, we discover electro-kinetic retardation caused strong hydrophobicity quaternary ammonium group-functionalized polynorbornene greatly prolong on Cu. This unconventional effect demonstrated increased Tafel slopes decreased sensitivity coverage change potentials. As a result, strongly hydrophobic electrodes exhibit ≈90 % at partial density 223 mA cm-2 more than twice bare or hydrophilic surfaces.

Using first-principles calculations combined with a constant-potential implicit solvent model, we comprehensively studied the activity of oxygen electrode reactions catalyzed by electride-supported FeN4-embedded graphene (FeN4Cx). The physical quantities in FeN4Cx/electrides, i.e., work function electrides, interlayer spacing, stability heterostructures, charge transferred to Fe, d-band center and adsorption free energy O, are highly intercorrelated, resulting being fully expressed nature electrides themselves, thereby achieving precise modulation selecting different electrides. Strikingly, FeN4PDCx/Ca2N FeN4PDCx/Y2C systems maintain high evolution reaction (OER) reduction (ORR) overpotential less than 0.46 0.62 V wide pH range. This provides an effective strategy for rational design efficient bifunctional catalysts as well model system simple activity-descriptor, helping realize significant advances devices.
