Deleted Journal, Journal Year: 2024, Volume and Issue: 1(2), P. 181 - 206

Published: Aug. 4, 2024

Abstract Metal–organic frameworks (MOFs) have emerged as promising materials in the realm of electrocatalysis due to their high surface area, tunable porosity, and versatile chemical functionality. However, practical application has been hampered by inherent limitations such low electrical conductivity a limited number active metal sites. Researchers addressed these challenges through various strategies, including enhancing incorporating conductive nanoparticles, modifying structure composition MOFs replacing nodes functionalizing linkers, preparing catalysts thermal processes decarburization conversion into oxides, phosphides (MPs), sulfides (MSs). This review provided comprehensive summary strategies that were employed enhance electroactivity for improved electrocatalytic performance recent years. It also explored future directions potential innovations design synthesis MOF‐based electrocatalysts, offering valuable insights advancing sustainable energy technologies.

Spatially Immobilized PtPdFeCoNi as an Excellent Bifunctional Oxygen Electrocatalyst for Zinc–Air Battery

Advanced Functional Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 20, 2024

Abstract Developing efficient oxygen electrocatalysts with low cost, high catalytic activity, and robust stability remains a formidable challenge for rechargeable zinc–air batteries (ZABs). Herein, highly dispersed ultrasmall PtPdFeCoNi high‐entropy alloy nanoparticles size of ≈ 2 nm randomly distributed multimetallic single atoms spatially immobilized on the 3D hierarchically ordered porous nitrogen‐doped carbon skeleton (denoted as PtPdFeCoNi/HOPNC) are successfully synthesized via ultra‐rapid Joule heating process. The spatial immobilization HOPNC is key to dispersion multi‐active sites electrocatalysts, formed hierarchical pore structure conducive successful construction rapid mass transfer channel. As result, as‐prepared PtPdFeCoNi/HOPNC exhibits positive half‐wave potential 0.866 V versus RHE reduction reaction (ORR), overpotential 310 mV at 10 mA cm −2 evolution (OER), Tafel slopes both ORR OER. Furthermore, ZAB using bifunctional catalysts excellent rate performances superior cycling stability, surpassing that commercial Pt/C‐RuO mixture. strategy provides new idea design synthesis various applications.

Photocatalytic Semi‐Hydrogenation of Acetylene to Polymer‐Grade Ethylene with Molecular and Metal–Organic Framework Cobaloximes

Advanced Materials, Journal Year: 2024, Volume and Issue: unknown

Published: Oct. 22, 2024

Abstract The semi‐hydrogenation of acetylene in ethylene‐rich gas streams is a high‐priority industrial chemical reaction for producing polymer‐grade ethylene. Traditional thermocatalytic routes reduction to ethylene, despite progress, still require high temperatures and H 2 consumption, possess relatively low selectivity, use noble metal catalyst. Light‐powered strategies are starting emerge, given that they have the potential directly abundant sustainable solar irradiation, but ineffective. Here an efficient, >99.9% selective, visible‐light powered, catalytic conversion ethylene reported. catalyst homogeneous molecular cobaloxime operates tandem with photosensitizer at room temperature bypasses non‐environmentally friendly flammable feed. proceeds through cobalt‐hydride intermediate ≈100% under competitive (ethylene co‐feed) conditions after only 50 min, no evolution or over‐hydrogenation ethane. further incorporated as linker metal–organic framework; result heterogeneous can be recycled up six times remains catalytically active 48 h, before significant loss performance observed.
