Atomically Dispersed Reactive Centers for Electrocatalytic CO₂ Reduction and Water Splitting

Angewandte Chemie International Edition, Год журнала: 2020, Номер 60(24), С. 13177 - 13196

Опубликована: Дек. 14, 2020

Developing electrocatalytic energy conversion technologies for replacing the traditional source is highly expected to resolve fossil fuel exhaustion and related environmental problems. Exploring stable high-efficiency electrocatalysts of vital importance promotion these technologies. Single-atom catalysts (SACs), with atomically distributed active sites on supports, perform as emerging materials in catalysis present promising prospects a wide range applications. The rationally designed near-range coordination environment, long-range electronic interaction microenvironment sphere cast huge influence reaction mechanism catalytic performance SACs. In current Review, some recent developments dispersed reactive centers CO2 reduction water splitting are well summarized. underlying structure-activity relationship elaborated based progresses various operando investigations. Finally, by highlighting challenges development single-atom catalysis, we hope shed light future research SACs conversion.

Rationally Designing Efficient Electrocatalysts for Direct Seawater Splitting: Challenges, Achievements, and Promises

Angewandte Chemie International Edition, Год журнала: 2022, Номер 61(45)

Опубликована: Авг. 23, 2022

Directly splitting seawater to produce hydrogen provides a promising pathway for energy and environmental sustainability. However, current faces many challenges because of the sluggish kinetics, presence impurities, membrane contamination, competitive chloride oxidation reaction at anode, which makes it more difficult than freshwater splitting. This Review firstly introduces basic mechanisms anode cathode reactions during We critically analyze primary principles designing catalysts in terms both oxygen evolution reactions, including with noble metal, metal free, metal-free catalysts. Strategies design effective catalysts, such as active site population, synergistic effect regulation, surface engineering, are discussed. Furthermore, promises, perspectives, developing technologies clean generation summarized.

Dynamics and control of active sites in hierarchically nanostructured cobalt phosphide/chalcogenide-based electrocatalysts for water splitting

Energy & Environmental Science, Год журнала: 2022, Номер 15(2), С. 727 - 739

Опубликована: Янв. 1, 2022

The rational design of efficient electrocatalysts for industrial water splitting is essential to generate sustainable hydrogen fuel. However, a comprehensive understanding the complex catalytic mechanisms under harsh reaction conditions remains major challenge. We apply self-templated strategy introduce hierarchically nanostructured "all-surface" Fe-doped cobalt phosphide nanoboxes (Co@CoFe-P NBs) as alternative industrial-scale applications.
