Academician Tao Zhang and co‐workers designed prepared the first Pt 1 /FeO x “single‐atom catalysts (SACs)” in 2011, which fills gap between homogeneous catalysis heterogeneous catalysis. The “single‐cluster (SCCs)” (e.g., triatomic clusters multiatomic clusters) with continuous metal sites fully exposed atomic structures exhibit unique synergistic effects high catalytic efficiencies. SACs SCCs can undergo dynamic structural evolution both geometric electronic actual conditions. of two atomic‐level presents great opportunities challenges for real mechanism stability. Herein, a new concept “dynamic (DCSs)” is proposed to illuminate these phenomena fields. Particularly, DCSs are divided into three categories: 1) structures, 2) coordinated 3) structures. scientific significances application principles versatile fields (including thermocatalysis, photocatalysis, electrocatalysis) summarized. underlying rational proposals also provided this perspective review.

Tuning the CO₂ and CO Electroreduction by Rate-Determining and Selectivity-Determining Steps

ACS Applied Materials & Interfaces, Journal Year: 2025, Volume and Issue: unknown

Published: Feb. 16, 2025

The renewable electricity-driven CO2 and CO reduction represents a promising approach for reducing the footprint toward carbon neutrality. Substantial research developments have been achieved in designing catalysts reaction interfaces enhanced electrocatalytic activity selectivity, investigation understanding of complex mechanisms also extensively investigated by both situ characterizations theoretical investigations. Although quasi-equilibrium rate-determining step assumptions are widely used electrochemical kinetics, overall rate is generally determined series elementary steps, influence certain can be quantified based on degree control theory. For complicated networks CO(2) reduction, not only steps but subsequent selectivity-determining play critical roles, especially product selectivity. In this Perspective, we summarize strategies that tune selectivity their impacts respectively. addition, describe coupling electroreduction with other (electro)chemical reactions, such as nitrite methane oxidation, to form value-added products. At end, current challenges opportunities field discussed inspire further development next stage.

Abstract The electrocatalytic conversion of CO 2 into valuable multi‐carbon (C 2+ ) products using Cu‐based catalysts has attracted significant attention. This review provides a comprehensive overview recent advances in catalyst design to improve C selectivity and operational stability. It begins with an analysis the fundamental reaction pathways for formation, encompassing both established emerging mechanisms, which offer critical insights design. In situ techniques, essential validating these by real‐time observation intermediates material evolution, are also introduced. A key focus this is placed on how enhance through manipulation, particularly emphasizing catalytic site construction promote C─C coupling via increasing * coverage optimizing protonation. Additionally, challenge maintaining activity under conditions discussed, highlighting reduction active charged Cu species materials reconstruction as major obstacles. To address these, describes strategies preserve sites control including novel utilization mitigation reconstruction. By presenting developments challenges ahead, aims guide future conversion.
