Emerging electrocatalytic activities in transition metal selenides: synthesis, electronic modulation, and structure-performance correlations

A Mini Review on Transition Metal Chalcogenides for Electrocatalytic Water Splitting: Bridging Material Design and Practical Application

“…Many works in literature have suggested that it was inevitable for the most of TMCs undergoing morphological evolution and electronic reconfiguration on the surfaces during water electrolysis, while the driving force of surface reconstruction and the corresponding impacts on the stability is still ambiguous. Although the large-current density performances of water splitting electrocatalysts are drawing more and more attentions from researchers recently, most recent works in literature still focused on material design of TMCs as electrocatalysts for water splitting, and their performances and stabilities in practical electrolyzers are less reported. , In summary, the gap between materials design and practical implementation of TMCs as water splitting electrocatalysts is still large and narrows slowly.…”

Recent advances in molybdenum diselenide-based electrocatalysts: preparation and application in the hydrogen evolution reaction

“…Recently, Sim and coworkers summarized some main factors to explain the origin of the improved HER performance. 218 Hence, the electrocatalytic mechanism for improved HER performance will depend upon the concrete structure, morphology, composition, defects, vacancies, and interfaces of the catalyst to suggest the origin of HER activity and unveil the structure–performance correlations; 211 in particular, an effective and advanced characterization technique is necessary.…”

Amorphizing Metal Selenides-Based ROS Biocatalysts at Surface Nanolayer toward Ultrafast Inflammatory Diabetic Wound Healing

“…Notably, it has been found that the poor ROS catalytic activity of these metal compounds should be attributed to their deteriorated reversible redox properties of metal centers that originate from the coordinated electronegative atoms. , Thus, searching for a suitable strategy to overcome the unbalanced multielectron reactions and realize reversible catalytic cycles with ultrafast kinetics is essential. Among various metal compounds, transition metal selenides have become important catalytic materials to substitute the current metal oxides for diverse catalytic reactions due to their higher metallicity and tunable bandgap, atom environments, and electronic structures . However, pristine metal selenides also suffer from some inherent drawbacks for catalytic ROS scavenging, such as low catalytic activity and poor broad-spectrum scavenging ability.…”

“…Among various metal compounds, transition metal selenides have become important catalytic materials to substitute the current metal oxides for diverse catalytic reactions due to their higher metallicity and tunable bandgap, atom environments, and electronic structures. 43 However, pristine metal selenides also suffer from some inherent drawbacks for catalytic ROS scavenging, such as low catalytic activity and poor broadspectrum scavenging ability. Therefore, it is crucial to develop an efficient strategy to adjust the catalytic atoms and bond microenvironments of metal selenides to obtain multifaceted and highly efficient ROS-scavenging abilities.…”
