One-pot synthesis of Ni nanoparticle/ordered mesoporous carbon composite electrode materials for electrocatalytic reduction of aromatic ketones

Abstract

A simple one-pot synthesis of Ni nanoparticle/ordered mesoporous carbon composite electrode materials is demonstrated for electrosynthesis for the first time. The obtained nanocomposites have uniform mesopore sizes (3.0–3.7 nm), large specific surface areas (506–633 m² g⁻¹), high pore volumes (0.28–0.38 cm³ g⁻¹), well-graphitized carbon frameworks, and uniformly dispersed Ni nanoparticles (7–15 nm) embedded in the carbon pore walls. The prepared materials show very high performance in the selective (∼84%) electrocatalytic reduction of aromatic ketones into alcohols (∼79%).
