From June 14 to July 5, HUST-NTU Academic Lecture Series was successfully held in the School of Chemistry and Chemical Engineering, HUST. At the invitation of Prof. Xia Baoyu and Prof. Yang Liming of the School of Chemistry and Chemical Engineering HUST, Prof. Wang Xin and Assoc Prof. Liu Bing of School of Chemical and Biomedical Engineering NTU, Prof. Yan Qingyu and Assoc Prof. Liu Zheng of School of Materials Science and Engineering NTU gave invited lectures. More than 400 students and researchers from universities such as Huazhong University of Science and Technology, Nankai University and other domestic universities participated online.

In this lecture, Prof. Wang Xin introduced that heterogeneous molecular catalysts based on transition metal complexes supported on conductive substrate have received increasing attention for their potential application in electrochemical energy conversion. He reported some progress made in his lab in this area. The heterogenization of molecular catalyst was first demonstrated by anchoring molecular Co2+ ions onto N/S/O doped graphene. In another demonstration of similar molecular system based on Ni2+, he found for the first time that the presence of Fe3+ ions in the solution could generate heterogeneous Ni-Fe dual sites anchored on doped graphene. These Ni-Fe sites exhibited drastically improved OER activity. It is revealed that the Ni-Fe sites adsorbed HO- ions with a bridge geometry, which facilitated the OER electrocatalysis. Using CO2 reduction on various well-defined molecular catalysts as a probe, he also demonstrated the importance of axial ligand and relay molecule in improving interfacial electron transfer and subsequent electrocatalytic activity.

Assoc Prof. Liu Bin summarized his recent progresses towards design of efficient oxygen electrocatalysts for various electrochemical energy conversion and storage applications. The design strategies include: 1. How to experimentally determine binding strength of reactive intermediates. 2. How to tune binding strength of reactive intermediates by surface engineering. 3. How to break the scaling relationship.

The industrial synthesis of ammonia (NH3), a key feedstock for synthetic fertilizer, is relying on traditional Haber-Bosch approach under extremely harsh conditions (100-200 bar and 400-500. Nitrogen fixation via electrocatalytic process provides an intriguing route at ambient conditions, potentially realizing a sustainable approach when driven by renewable electricity (wind power, hydroelectric power, etc.). In this presentation, Prof. Yan Qingyu discussed their recent works on the electrocatalytic processes of nitrogen oxidation, nitrogen reduction, and urea synthesis, and the role of new catalyst design and analysis of the reaction pathway.

In this lecture, Prof. Liu Zheng first introduced the difference between ordinary materials and two-dimensional materials, then he explained his research in the synthesis of 2D materials and electrocatalytic mechanism in detail, including the synthesis methods of 2D materials, and key elements of 2D TMDS synthesis. In addition, Prof. Liu introduced his analysis of the mechanism of electrocatalysis using a simple two-dimensional material model, which can be used to design semiconductor catalysts more electrically and to improve the charge transport mechanism in semiconductor electrochemistry. In the end, Prof. Liu Zheng mentioned the combination of material synthesis and machine learning, which can be used to synthesize 2D materials accurately through smart synthesis and smart analysis.

During the Q&A part, Prof. Wang Xin, Assoc Prof. Liu Bing, Prof. Yan Qingyu and Assoc Prof. Liu Zheng exchanged ideas with the participants, and had a heated discussion on hot research issues, providing ideas and guidance to researchers and students in related research fields.
