Recent advances in the synthesis and biological applications of cerium oxide nanoparticles
上海师范大学学报. 自然科学版, 2019 Cerium oxide(CeO2-x,x=0~0.5) nanoparticles are attractive as a kind of widely used rare earth oxides due to their excellent catalytic activities,which are originated from the reversible conversion between Ce3+ and Ce4+ as well as the existence of oxygen ...

Advanced Science, EarlyView.This review explores how hemoglobin‐based oxygen carriers (HBOCs) combined with nanozymes create multifunctional materials that deliver oxygen while maintaining redox homeostasis. Beyond artificial blood substitutes, these constructs enable wound healing with light‐triggered oxygen release, cancer therapy through enhanced oxygenation and reactive ...

Angewandte Chemie, EarlyView.A critical step, dry reforming of methane (DRM) converts biogas into useful syngas. Yet trace H2S in biogas rapidly poisons DRM catalysts, limiting practical use. We developed a robust Pt/CeO2 catalyst sustaining DRM activity via CO2‐induced reverse lattice oxygen spillover in H2S‐rich environments.

Advanced Science, EarlyView.A novel optical thermometer exploits the rare UV emission of Yb2+ ions in a SrB4O7 host, enabling highly sensitive, non‐contact temperature measurements from 80 to 420 K. The applied multiple linear regression (MLR) analysis results in a multiple increase in the resulting temperature sensitivity.

Enzyme‐Like Synthetic Cleft for Light‐Driven Water‐Oxidation Catalysis Via an Oxide Relay Pathway
Angewandte Chemie, EarlyView.A carboxylic acid group introduced into the second coordination sphere of a Ru(bda) water oxidation catalyst forms a defined hydrogen bond within the catalytic cleft. This interaction locks the group in place and enables an intramolecular oxide relay pathway between Ru(V)═O and the carboxylate group, providing a distinct and efficient route for O─O ...

Tailored Synthesis of Doped Non‐Layered Oxide Nanosheets Using Designed Solid‐State Surfactants
Advanced Science, EarlyView.This work reports a solid‐state surfactant templating method that enables precise doping of non‐layered oxide nanosheets. Using ceria and rare‐earth elements as model systems, we established design principles for solid‐state surfactants containing multiple elements.
