Advanced Functional Materials, Год журнала: 2023, Номер 33(30)

Опубликована: Апрель 20, 2023

Abstract Recently, atomically dispersed dual‐metal sites carbocatalysts (DMSCs) make a wave in the field of persulfate‐based advanced oxidation processes (PS‐AOPs) light their ≈100% atomic utilization efficiency, high density active sites, and superior catalytic activity. This review aims to provide state‐of‐the‐art overview on development DMSCs for activating PS. Initially, types properties are summarized, as well role doping different heteroatoms is discussed. Subsequently, carbon carriers methods synthesis outlined. After that, mechanism application activation PS toward organic contaminants degradation revealed. Particularly, nonradical pathway described, necessity coupling DMSCs‐based PS‐AOPs other practical water treatment emphasized. Finally, formidable challenges future research directions proposed. expected insight into preparation nanomaterials broaden path environmental applications.

Multiscale Anion-Hybrid in Atomic Ni Sites for High-Rate Water Electrolysis: Insights into the Charge Accumulation Mechanism

Journal of the American Chemical Society, Год журнала: 2024, Номер 146(20), С. 14194 - 14202

Опубликована: Май 8, 2024

Single-atom catalysts, characterized by transition metal–(N/O)4 units on nanocarbon (M–(N/O)4–C), have emerged as efficient performers in water electrolysis. However, there are few guiding principles for accurately controlling the ligand fields of single atoms to further stimulate catalyst activities. Herein, using Ni–(N/O)4–C unit a model, we develop modification P anion outer shells modulate morphology ligand. The thus prepared possesses high activity and excellent long-term durability, surpassing commercial Pt/C, RuO2, currently reported single-atom catalysts. Notably, mechanistic studies demonstrated that pseudocapacitive feature multiscale anion-hybrid is considerable at accumulating enough positive charge [Q], contributing oxygen evolution reaction (OER) order (β) through rate formula. DFT calculations also indicate catalytic decided suitable barrier energy intermediates due accumulation. This work reveals origin multihybrid nanocarbon, providing clear experiential formula designing electronic configuration catalysts boost electrocatalytic performance.
