Constructing Transition Metal Single-Atom-Modified MoB₂: Extraordinary Electrocatalytic Hydrogen Evolution and Mechanism Investigation

Conjugation and Topology Engineering of 2D π‐d Conjugated Metal–Organic Frameworks for Robust Potassium Organic Batteries

“…The highly dispersed Cu species (bright dots) in sql-Cu-TBA-MOF were also performed by aberration-corrected high-angle annular dark-field scanning TEM (AC HAADF-STEM) (Figure S3). [14] To further distinguish the valence states of different elements, X-ray photoelectron spectroscopy (XPS) was determined. The XPS survey spectrum of sql-Cu-TBA-MOF is extremely consistent with EDS elemental mapping images (Figure S4a), while the other element (N) is present in kgm-Cu-TBA-MOF (Figure S5a) (this phenomenon could be caused by the addition of ammonium hydroxide).…”

“…The group corroborated the applicability of TiB as an electrical device in the environment of a 2D electron gas in vacuum conditions and as the remarkable HER catalyst on account of a minimal 0.03 eV ΔG H *. Yang et al 29 recently examined the scope of a single atom catalyst (SAC) decorated MoB 2 MBene to augment the exposed active sites for the HER process and to comprehend the role of the SAC in the reaction mechanism. The group reported the high Fe/Co/Ni loading (∼7 wt %) on the MoB 2 surface with Ni@MoB 2 delivering an optimum electrochemical HER performance in acidic as well as alkaline conditions.…”

“…The studies of Zhou et al, Wei et al, and Xiong et al have further bolstered the gamut of MBenes with optimizing MAB ternary phase and synthetic protocols (Figure j–l). There are sporadic reports of MBenes applicability toward environmental applications of HER, CO 2 RR, and the nitrogen reduction reaction (NRR) with respect to theoretical foundation and experimental observations. , Recently, there is the growing interest of researchers in escalating the HER, NRR, and CO 2 RR efficiencies of MBenes by tailoring their structural and compositional properties as well depicted in Figure , parts m, n, and o, respectively. Herein, we present an ordered precise commentary on MBenes to address their recent advances, challenges, and prospects for HER, CO 2 RR, and NRR applications.…”
