Developments of advanced sensors for NO 2 gas with high sensitivity and selectivity are
essential but challenging. In this work, a Ce-doped ZnO nanoarray (termed as CZO) was …

Surface oxygen vacancy defects (OV) are regarded to be beneficial to the gas sensing
behavior by significantly improving the carrier density and providing more oxygen …

Detection of toxic and explosive gases in a selective manner and with higher sensitivity in
industries and homes remains very challenging. Therefore, herein, we report on the ultra …

Enhancing the optical emission of cerium oxide nanoparticles is essential for potential
biomedical applications. In the present work, we report a simple chemical precipitation …

Highly sensitive and selective detection of formaldehyde is of great significance for indoor
air quality. In this work, semiconductor gas sensors with high response have been …

Catalysts used for heterogeneous processes are usually composed of metal nanoparticles
dispersed over a high–surface-area support. In recent years, near-ambient pressure …

Periodontitis is a common bacteria-borne inflammatory disease that can damage the
supporting structures of teeth, eventually leading to tooth loss and systemic inflammations …

Supported metal nanoparticles are used as heterogeneous catalysts but often deactivated
due to sintering at high temperatures. Confining metal species into a porous matrix reduces …

In situ structural and chemical state characterization of Rh/CeO2 and Ni/CeO2 catalysts
during atmospheric pressure CO2 methanation has been performed by a combined array of …

Abstract In this work, CeO 2/Co 3 O 4 microflowers have been prepared by a facile bimetallic
metal-organic framework (MOF) derivatization method. By optimizing the calcination …
