Mesoporous Electrocatalysts with p-n Heterojunctions for Efficient Electroreduction of CO and N to Urea.

The electrocatalytic synthesis of high-value-added urea by activating N and CO is a green synthesis technology that has achieved carbon neutrality. However, the chemical adsorption and C-N coupling ability of N and CO on the surface of the catalyst are generally poor, greatly limiting the improvement of electrocatalytic activity and selectivity in electrocatalytic urea synthesis. Herein, novel hierarchical mesoporous CeO/CoO heterostructures are fabricated, and at an ultralow applied voltage of -0.

Facile green synthetic graphene-based Co-Fe Prussian blue analogues as an activator of peroxymonosulfate for the degradation of levofloxacin hydrochloride.

A kind of Co-Fe Prussian blue analogues (Co-Fe PBAs), cobalt hexacyanoferrate Co[Fe(CN)], and graphene oxide (GO) were combined to synthesize magnetically separable Co-Fe PBAs@rGO nanocomposites through a simple two-step hydrothermal method. The crystalline structure, morphology and textural properties of the Co-Fe PBAs@rGO nanocomposites were characterized. The catalytic performance of the nanocomposites was evaluated by PMS activation, with Levofloxacin Hydrochloride (LVF) as the target contaminant.
