Dr. Wee-Jun ONG Publishes in Top Journal, Chem (Impact Factor >14)

2018-10-11

The Office of Research and Innovation congratulates Assistant Professor Dr. Wee-Jun ONG on his role as the joint first and corresponding author of a paper entitled “Surface and Heterointerface Engineering of 2D MXenes and Their Nanocomposites: Insights into Electro- and Photocatalysis.” The paper was published on 27th September 2018 in Chem, which is one of the world’s top-ranked multidisciplinary chemistry journals (rank: 9/171). Chem, that has the latest impact factor of 14.104, is a sister journal to Cell Press’s flagship journal, Cell.

The Editor-in-Chief of Chem, Dr Robert Eagling, has invited the research team – five (5) scientists affiliated with Xiamen University Malaysia and Wuhan University of Technology (China), to contribute this state-of-the-art research in the emerging field of catalysis. With the advancement of nanoscience and nanotechnology in the 21st century, catalysis is one of the key technologies to address some of the world’s pressing issues – increasingly severe environmental pollution and energy shortages.

2D MXenes for diverse applications such as hydrogen evolution reaction (HER), oxygen evolution reaction (OER), oxygen reduction reaction (ORR), nitrogen reduction reaction (N2RR), carbon dioxide reduction reaction (CO2RR) and pollutant degradation. (Chem 2018, DOI: 10.1016/j.chempr.2018.08.037)

Conventional catalysts have the disadvantages of low catalytic selectivity, poor stability and low efficiency. In view of that, the novel 2D transition metal carbides, nitrides and carbonitrides (MXenes) endow vast potential in the realm of energy and environmental science because of their intrinsic nanoscale layer structures, large specific surface area, tunable band structure, superb carrier mobility, good hydrophilicity and excellent electrical conductivity. This renders the engineering of MXene-based nanocomposites as a versatile approach to develop (photo)electrocatalysts for artificial photosynthesis and environmental remediation.

The research exemplifies how chemistry can help to achieve the Sustainable Development Goals identified by the United Nations. The research team aligns their work with “SDG7: Affordable and Clean Energy,” a goal to ensure access to affordable, reliable, sustainable and modern energy for all.

Dr Wee-Jun Ong reveals the future direction of the research:

 “Our research finding concludes with invigorating perspectives, outlooks, and formidable challenges in the future development of MXene-based materials for sustainable applications. The flourishing development and intense efforts from all disciplines will eventually bridge the gap between innovative catalyst development and practical use for commercialization in the years to come.”
