Abstract

The perovskite-like La_0.96Sr_0.04NiO_3-δ nanozyme with perovskite structure was effectively synthesized by sol-gel method and high temperature calcination method. Through a range of characterization methods, we discovered that doping with trace levels of Sr might alter the surface electron states of La_0.96Sr_0.04NiO_3-δ and increase the quantity of oxygen vacancies. During the reaction phase, La_0.96Sr_0.04NiO_3-δ exhibits excellent peroxidase-like activity in the electron transfer from Sr⁰ to Ni²⁺. Peroxidase-like activity served as the basis for the successful establishment of the epinephrine color sensor. This strategy is better than others because of its wide detection range and low detection limit. The result was to the successful construction of an epinephrine smart sensing platform that included cellphones and offered other choices for fast and precise on-site detection.

期刊介绍： The Journal of Physics and Chemistry of Solids is a well-established international medium for publication of archival research in condensed matter and materials sciences. Areas of interest broadly include experimental and theoretical research on electronic, magnetic, spectroscopic and structural properties as well as the statistical mechanics and thermodynamics of materials. The focus is on gaining physical and chemical insight into the properties and potential applications of condensed matter systems. Within the broad scope of the journal, beyond regular contributions, the editors have identified submissions in the following areas of physics and chemistry of solids to be of special current interest to the journal: Low-dimensional systems Exotic states of quantum electron matter including topological phases Energy conversion and storage Interfaces, nanoparticles and catalysts.
