Selective Adsorption of Chlorine Species on RuO Sites for Efficient Elimination of Vinyl Chloride on the Ru/SnO Catalyst.

The main bottleneck in the catalytic combustion of chlorinated volatile organic compounds (CVOCs) is deactivation and the production of chlorine-containing byproducts originating from the chlorine species deposited on the catalyst. Herein, Ru supported on SnO (Ru/SnO) was prepared with the lattice matching principle. As RuO and SnO are both rutile phases, Ru species were present as highly dispersed RuO particles on the Ru/SnO catalyst.

Origin of oxygen-redox and transition metals dissolution in Ni-rich LiNiCoMnO cathode.

Recently, Ni-rich LiNiCoMnO (x ≥ 0.8) draw significant research attention as cathode materials in lithium-ion batteries due to their superiority in energy density. However, the oxygen release and the transition metals (TMs) dissolution during the (dis)charging process lead to serious safety issues and capacity loss, which highly prevent its application.

Ruthenium oxides supported on heterostructured CoPO-MCF materials for catalytic oxidation of vinyl chloride emissions.

A novel heterostructured material, cobalt phosphate-SiO mesostructured cellular foams (CoPO-MCF), was successfully synthesized by in situ growth. The material was characterized by X-ray diffraction (XRD), nitrogen sorption, temperature-programmed reduction (H-TPR and CO-TPR), temperature-programmed desorption of NH (NH-TPD), and X-ray photoelectron spectroscopy (XPS). A ruthenium precursor was readily introduced and highly dispersed on the CoPO nanophases of the CoPO-MCF through an impregnation method.
