Over the last century, industrialization of agriculture and consumption fossil fuels have resulted in a significant imbalance redistribution nitrogen-containing resources. This has sparked an interest developing more sustainable resilient approaches for producing commodities such as fertilizers fuels. One largely neglected but emerging approach is photocatalytic nitrogen fixation. There evidence that this process occurs spontaneously terrestrial settings, it been demonstrated numerous engineered systems. Yet many questions still remain unanswered regarding rates, mechanisms, impacts photocatalytically fixed "out thin air". work reviews fascinating history reaction examines current progress toward understanding improving photofixation nitrogen. supplemented by quantitative review thermodynamic considerations limitations various mechanisms. Finally, future prospects preliminary performance targets fixation are discussed.

Electrocatalysts with single metal atoms as active sites have received increasing attention owing to their high atomic utilization efficiency and exotic catalytic activity selectivity. This review aims provide a comprehensive summary on the recent development of such single-atom electrocatalysts (SAECs) for various energy-conversion reactions. The discussion starts an introduction different types SAECs, followed by overview synthetic methodologies control dispersion atomically resolved characterization using state-of-the-art microscopic spectroscopic techniques. In recognition extensive applications electrocatalytic studies are dissected in terms important electrochemical reactions, including hydrogen evolution reaction (HER), oxygen (OER), reduction (ORR), carbon dioxide (CO2RR), nitrogen (NRR). Examples SAECs deliberated each case performance, structure-property relationships, enhancement mechanisms. A perspective is provided at end section about remaining challenges opportunities targeted reaction.

On the basis of constraints from reported experimental observations and density functional theory simulations, we propose a mechanism for reduction CO2 to C2 products on copper electrodes. To model effects an applied potential bias reactions, calculations are carried out with variable, fractional number electrons unit cell, which is optimized so that Fermi level matches actual chemical (i.e., bias); implicit electrolyte allows compensation surface charge neutrality maintained in overall simulation cell. Our explains presence seven species have been detected reaction, as well other notable observations. Furthermore, our results shed light difference activities toward between (100) (111) facets copper. We compare methodologies findings those recent mechanistic studies copper-catalyzed reaction.

Abstract The electronic metal–support interaction (EMSI), which acts as a bridge between theoretical study and the design of heterogenous catalysts, has attracted much attention. Utilizing metal support is one most essential strategies to enhance electrocatalytic efficiency due structural synergetic promotion. To date, ideal model for realizing EMSI, many types single‐atom catalysts (SACs) have been developed. understanding on SACs also pushed higher level. However, systematic theories operando experiments are seldom reported, will be necessary put forward carried out, respectively. Herein, types, characterization, mechanism, applications EMSI comprehensively summarized discussed. In addition basic information above, challenges, opportunities, future development proposed present an overall view reference later research.

The notion of metal-free catalysts is used to refer carbon materials modified with nonmetallic elements. However, some claimed are prepared using metal-containing precursors. It highly contested that metal residues in nitrogen-doped (NC) play a crucial role the oxygen reduction reaction (ORR). In an attempt reconcile divergent views, definition for truly proposed and differences between NC M-Nx /C discussed. Metal impurities at levels usually undetectable by techniques such as XPS, XRD, EDX significantly promote ORR. Poisoning tests mask ions reveal involvement active sites or modifiers electronic structure NC. unique merits both discussed inspire development more advanced nonprecious-metal

We have carried out a periodic Kohn–Sham density functional theory investigation of the pathways by which carbon–carbon bonds could be formed during electrochemical reduction CO2 on Cu(100) using model that includes effects potential, solvent, and electrolyte. The potential was set relating applied to Fermi energy then calculating number electrons required simulation cell for specific energy. solvent included as continuum dielectric, electrolyte described linearized Poisson–Boltzmann model. calculated zero charge variety surfaces agrees with experiment within mean average error 0.09 V, thereby validating assumptions Analysis mechanism C–C bond formation revealed at low-applied occurs through CO dimer. However, high potentials, large activation barrier blocks this pathway; therefore, reaction adsorbed CHO CO. Rate parameters determined from our calculations were used simulate kinetics ethene over surface. An excellent match observed between previously reported measurements partial current function voltage variation in predicted microkinetic here is simple, fairly easy implement, involves only small increase computational cost neglecting field. Therefore, it can study composition energetics surface reactions wide reactions.
