Few-Layer Meets Crystalline Structure: Collaborative Efforts for Improving Photocatalytic H₂O₂ Generation over Carbon Nitride

ACS Applied Materials & Interfaces, Journal Year: 2024, Volume and Issue: 16(14), P. 17506 - 17516

Although the conversion of O2 and H2O to H2O2 over graphite carbon nitride (g-C3N4) has been realized by means photocatalytic process, catalytic activity pristine g-C3N4 is still restricted rapid charge recombination inadequate exposure active site. In this work, we propose a straightforward strategy solve these limitations decreasing thickness improving crystallinity g-C3N4, resulting in preparation few-layered crystalline (FL-CCN). Benefiting from minimal highly ordered in-plane triangular cavities within structure, FL-CCN processes an extended π-conjugated system with reduced transfer resistance expanded specific surface area. These features accelerate efficiency photogenerated separation contribute explore its sites. Consequently, exhibits significantly improved evolution rate (63.95 μmol g–1 h–1), which 7.8 times higher than that (8.15 during H2O. This systematic investigation offers valuable insights into mechanism generation development efficient catalysts.

Direct Methanol Fuel Cell with Porous Carbon-Supported PtRu Single-Atom Catalysts for Coproduction of Electricity and Value-Added Formate

ACS Catalysis, Journal Year: 2024, Volume and Issue: 14(12), P. 9134 - 9143

Published: May 30, 2024

Bottlenecks in direct methanol fuel cells (DMFCs) with conventional noble metals as anode catalysts involve the formation of valueless byproducts and carbon dioxide (CO2) emissions. Carbon-supported Pt single atoms have demonstrated high performance DMFCs. However, adsorbed intermediates (COads) strongly bind to single-atom sites, resulting complete oxidation CO2 low power densities. Herein, we developed a DMFC for CO2-emission-free coproduction electricity valuable formate using metal organic framework (MOF)-derived N-doped porous carbon-supported PtRu (referred PtRuSA/NPC) catalysts. The produces current densities 657 mA cm–2 97.4 mW cm–2, respectively, at potential 0.65 V 98.4% Faraday efficiency 80 °C. Density functional theory (DFT) calculations show that CH3OH molecules preferentially adsorb onto atoms, but their on PtRuSA/NPC is kinetically unfavorable due large energy barrier. This study offers pathway developing high-performance electrocatalysts
