Comprehensive Experiment Design on the Cerium-Vanadium Hollow Nanopillar Arrays Catalysts for Oxygen Evolution Reaction
A comprehensive experiment on the cerium-vanadium hollow nanopillar arrays(CeV-HNA)for electrocatalytic oxygen evolution reaction(OER)is designed based on the concept of research-oriented teaching and the scientific research achievements of the teacher.Vanadium based metal organic framework nanopillar arrays were firstly prepared on foam nickel by in-situ growth,and then Ce salt etching and high-temperature calcination were executed to construct CeV-HNA,achieving a freestanding catalyst.Furtherly,scanning electron microscopy,X-ray diffraction,X-ray photoelectron spectroscopy and other analytical testing methods were employed to characterize the structure of the prepared catalyst.Finally,its OER performance was investigated.This teaching experiment is comprehensive,cutting-edge and interesting,which contributes to exercise students'comprehensive practical abilities,stimulate their research enthusiasm and cultivate their innovation ability.
