Professor Xu Jiaqiang from Shanghai University came to Ningbo Institute of Materials for academic ex

On November 15th, Professor Xu Jiaqiang from Shanghai University was invited by Researcher Yang Minghui to Ningbo Institute of Materials Science, Chinese Academy of Sciences for academic exchanges, and gave an academic report entitled "Sensitive Mechanism and Material Design of Gas Sensors".

        In the report, Professor Xu Jiaqiang first introduced the relationship between the physical and chemical properties of gases and material design. The opportunities and challenges currently faced by gas sensors are introduced from the policy and market levels. The development of sensors in the future must be closely related to environmental safety, public safety, national security, energy conservation and emission reduction, environmental governance, security protection, Internet of Things, smart homes, smart cities, health care, wearable devices, and environmental monitoring. Then, the sensitive mechanism and research methods of gas sensor are introduced. And pointed out that the idea of semiconductor gas sensor material design must be high specific surface, high surface utilization, stable phase, high morphology retention, multi-level structure, low sensitivity, appropriate pore size, small volume material. After the report, Professor Xu answered the specific questions about gas sensors that everyone was concerned about in detail. Professor Xu's report expands new ideas for the future development of the team.
