Due to recent pandemic, 2022 2nd International Conference on Energy Engineering, New Energy Materials and Devices (NEMD 2022) was held virtually online during March 18-20, 2022. The decision to hold the virtual conference was made in compliance with many restrictions and regulations that were imposed by countries around the globe. Such restrictions were made to minimize the risk of people contracting or spreading the COVID-19 through physical contact. There were 110 individuals who attended this on-line conference, represented many countries including China, Kuwait, Algeria, Italy and Malaysia.The International Conference on Energy Engineering, New Energy Materials and Devices (NEMD), is an annual conference hold each year. NEMD provides a premier interdisciplinary platform for researchers, practitioners and educators to present and discuss not only the most recent innovations, trends, and concerns but also practical challenges encountered and solutions adopted in the fields of Energy Engineering, New Energy Materials and Devices. There will be participation of renowned Speakers, oral presentations, posters sessions and technical conferences related to the topics in the scientific program.During the conference, the conference model was divided into three sessions, including oral presentations, keynote speeches, and online Q&A discussion. In the first part, some scholars, whose submissions were selected as the excellent papers, were given about 5-10 minutes to perform their oral presentations one by one. Then in the second part, keynote speakers were each allocated 30-45 minutes to hold their speeches. In the second part, we invited two professors as our keynote speakers. A.Prof. Weiyong Yuan, Zhejiang University, China, performed a speech: Self-assembled hematite-based core-shell heteronanostructured arrays for photoelectrochemical water splitting. And then we had Prof. Fanian Shi, Shenyang University of Technology, China. He delivered a speech: Research progress of metal complexes and metal oxides as new-generation anode materials of lithium-ion batteries. Their insightful speeches had triggered heated discussion in the third session of the conference. Every participant praised this conference for disseminating useful and insightful knowledge.List of Committee member are available in this pdf.
