Abstract Recent years have witnessed an upsurge of interest in exploiting advanced photo‐/electrocatalysts for efficient energy conversion and environmental remediation. Constructing internal electric fields has been highlighted as a rising star to help facilitate various catalytic processes, with the merits promoting charge transfer/separation, optimizing redox potential creating effective active/adsorption sites. Internal are usually formed by polarization uneven distributions between different constituent layers, which widely exist piezoelectrics, polar surface terminations, heterostructure materials. Herein, groundbreaking interdisciplinary overview latest advances construction improve photo(electro)catalytic electrocatalytic activity is provided. This critical review begins encyclopedic summary classification, advantages, synthesis strategies fields. Subsequently, identification methods thoroughly discussed based on characterization techniques, experiments, theoretical calculations, can provide profound guidance in‐depth study To elaborate theory–structure–activity relationships fields, corresponding reaction mechanisms, modification strategies, performance jointly discussed, along discussion their practical applications. Finally, insightful analysis challenges future prospects field‐based catalysts discussed.

The regioisomeric effect, which refers to the different positions of heteroatoms and functional groups on a molecule, significantly impacts stability, physicochemical properties, chemical reactivity, coordination bonding organic compounds. These effects are critical for their commercial applications, notably in corrosion inhibition. Regioisomeric ligands, with unique spatial configurations groups, influence ability establish stable interactions metal surfaces. Certain regioisomers may exhibit enhanced affinity adsorption capacities based structural configurations, thereby facilitating formation more durable protective layer substrate. This review explores impact regioisomerism inhibition performance A literature survey reveals that identical substituents (e.g., –OH, –NH2, –COOH, –NO2, –OR), multiple bonds >CC< –CC–), or N, O, S) at varying diverse capabilities efficiencies. detailed analysis indicates certain regioisomers, due strategic placement achieve increased stability form relatively stronger complexes. enhances effectiveness chelation mechanisms. role group has been seldom observed documented previous studies. current research also underscores significance determining ligands. thorough understanding will assist scientists engineers developing effective inhibitors.

Spatially Confined Microcells: A Path toward TMD Catalyst Design

Chemical Reviews, Год журнала: 2024, Номер 124(11), С. 6952 - 7006

Опубликована: Май 15, 2024

With the ability to maximize exposure of nearly all active sites reactions, two-dimensional transition metal dichalcogenide (TMD) has become a fascinating new class materials for electrocatalysis. Recently, electrochemical microcells have been developed, and their unique spatial-confined capability enables understanding catalytic behaviors at single material level, significantly promoting this field. This Review provides an overview recent progress in microcell-based TMD electrocatalyst studies. We first introduced structural characteristics discussed site engineering strategies Later, we comprehensively described two distinct types microcells: window-confined on-chip microcell (OCEM) droplet-confined scanning cell microscopy (SECCM). Their setups, working principles, instrumentation were elucidated detail, respectively. Furthermore, summarized advances OCEM SECCM obtained catalysts, such as identification imaging, monitoring, modulation charge injection transport, electrostatic field gating. Finally, current challenges provided personal perspectives on research.
