“…This experiment involves the synthesis, characterization, and catalytic performance testing of PbO 2 particles with different crystal forms. Students conduct experiments using ordinary experimental instruments and simple synthesis conditions, which are highly feasible and suitable as an experimental project for undergraduate teaching. − Through these experiments, students can have a certain understanding of innovative material synthesis technology, characterization methods, and applied research in related disciplines. This will improve students’ practical ability and knowledge application ability, cultivate students’ innovation ability and inquiry awareness, strengthen students’ sustainable development concept and green environmental awareness, and inspire students’ enthusiasm and interest in the scientific research direction of electrocatalytic ammonia synthesis.…”

Although the present university-level chemistry experimental curriculum has been extensive and well-designed, it lacks a connection with the scientific research field, especially the frontier field. It is crucial to incorporate recent discoveries through new experiment designs to bridge this gap and boost the value of the undergraduate experimental course. Under the background of advancing with the times, this paper integrates the scientific research results of electrocatalytic ammonia synthesis (through nitrogen reduction reaction, NRR) into the undergraduate teaching classes, which is conducive to improving students' scientific analysis ability and their green environmental awareness. Two lead dioxide catalysts with different crystal phases were prepared on a carbon cloth substrate by a simple water bath method. The structure, composition, and morphology of the two catalysts were characterized, and the electrocatalytic ammonia synthesis performance of the two catalysts was explored. This experimental project not only covers the teaching content of inorganic, analytical, and physical chemistry but also cultivates students' basic experimental operation skills and the ability to use modern instruments to analyze the structure of materials, stimulate students' interest in learning, and improve students' scientific research literacy.

At the National University of Luján, traditional classroom-based instruction characterized the analytical chemistry courses. However, in response to evolving educational needs, a transition to hybrid education combining virtual and face-to-face activities is occurring. In this context, some questions arise: Can all face-to-face activities be replaced by virtual activities? What benefits does the inclusion of virtual activities bring to the curriculum? Reflecting on the experiences gained during the virtual instruction period that occurred due to the pandemic, the teaching group recognized the value of integrating virtual and face-to-face components. In a comparative assessment of teaching tools, the consensus emerged that a blended approach is crucial for effective analytical chemistry education in the current educational landscape. The findings indicated that, for theoretical lessons, a hybrid approach with face-to-face sessions complemented by asynchronous virtual tools proved to be advantageous. This allowed students the flexibility to review lessons at their convenience. Regarding practical work, a preference for face-to-face instruction was noted, as it facilitated hands-on experience in laboratories with real equipment and samples. However, it was found that the simulation software for gas and liquid chromatography equipment allowed the incorporation of valuable experiences for the study of both methodologies without extending the time required to carry out the practical work or requiring new inputs.
