Tailoring high performance, stable, and earth-abundant electrocatalysts for water oxidation is of fundamental importance for the development of promising energy conversion and storage technologies. In this work, we report a remarkably simple and efficient approach for the preparation of ZnCo-layered double hydroxides and reduced graphene oxide (RGO/ZnCo-LDH) nanocomposites via a facile one-pot coprecipitation method. The resulting RGO/ZnCo-LDH complex investigated for the first time as a catalyst for oxygen evolution reaction (OER) exhibits higher electrocatalytic activity (with onset overpotential ∼330 mV in 0.1 M KOH) and excellent stability than pristine ZnCo-layered double hydroxides and commercial Pt/C, making it a highly efficient nonprecious metal-based novel LDH composite electrocatalyst for OER.

A nickel-modified polyoxometalate compound was synthesized which exhibited excellent catalytic activity (conversion: 41.63%; selectivity: 97.21%) for selective oxidation of cyclooctene using air as an oxidant without a solvent.

Two microporous metal-organic frameworks formulated as H2In3O(OH)3(1,3-bdc)3 (1) and HIn(1,4-bdc)2 (2) (bdc = benzenedicarboxylic) were designed and synthesized. Compound 2 shows a high adsorption selectivity for CO2 over N2 as well as a high stability.
