The reductive transformation of Cr(VI) into Cr(III) mediated by formic acid with efficient, stable, and cost-effective catalysts is a promising strategy for remediating contamination. Herein, we report the facile construction uniform Co@NC nanosheet-assembled microflowers reduction Cr(VI). Both experimental results density functional theory (DFT) calculations reveal vital role intensive interfacial electronic interaction between Co nanoparticles N-doped carbon layer in facilitating anchoring dispersion within framework. electron transfer from to NC contributes Cr2O72– ions, promoting subsequent H-transfer reaction. A Langmuir–Hinshelwood kinetic model has been established catalyzed CNCF2 (pyrolyzed at 700 °C), which shows superior reaction performance. This study provides delicately design well-assembled heterostructures rich interfaces strong interactions series applications environmental/thermal catalysis.

Coupled Interface and Oxygen-Defect Engineering in Co₃O₄/CoMoO₄ Heterostructures toward Active Oxidation of Ethylbenzene

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(11), P. 5142 - 5150

Published: March 4, 2024

The catalytic oxidation of ethylbenzene (EB) is a promising route to produce acetophenone (AcPO). Unfortunately, it remains great challenge achieve the highly efficient EB under solvent-free conditions using molecular oxygen as sole oxidant. In this contribution, we present facile strategy construct hierarchical vacancy-rich Co3O4/CoMoO4 heterostructures (Vö-CCMO), which delivers high yield value 74.5% at 83.2% conversion and selectivity 89.6% AcPO. Both experimental studies theoretical calculations substantiate important role oxygen-defect engineering triggered by modified chemistry environment interfaces between biphasic phases, contributes good performance. This work illustrates paradigm for exploit advanced catalysts toward boosting reaction in more practical way.

Manipulation of Electronic Effect and Assembly Architecture to Invoke Oxidation of Ethylbenzene by Hierarchical Co₃O₄ Wreaths

Inorganic Chemistry, Journal Year: 2024, Volume and Issue: 63(19), P. 8938 - 8947

Published: April 29, 2024

A high-performance transition-metal oxide catalyst can be designed by appropriately integrating the concepts of morphology regulation and electronic structure modulation. In this work, hierarchical Co3O4 wreaths (CCW) enriched with oxygen vacancies (Ov) were facilely constructed for selective oxidation ethylbenzene (EB) to acetophenone (AP). Under screened optimal reaction conditions, CCW offer a 79.1% conversion EB (ri = 0.244 mol gcat–1 h–1) accompanied selectivity 92.3% AP. The good performance attributed cooperation defect engineering architecture design, which synergistically facilitate augmenting intrinsic reactivity accessibility active sites. This work presents reliable route construct transitional metal via manipulation effect assembly beyond.
