This book focuses on recent developments in the field of two-dimensional nanomaterials for environmental applications. Due to their high surface area and tunable surface chemistry, two-dimensional nanomaterials are currently garnering great interest for environmental remediation applications. This book compiles contributed chapters from active international researchers dealing with the development of state-of-the-art two-dimensional nanomaterials in environmental applications such as water and wastewater treatment, adsorption, photocatalysis, membrane separation, desalination, deionization, environmental pollutants sensing/detection, carbon-dioxide capture and catalytic conversion, microbial treatment, and electrochemical remediation.
Each chapter provides an essential and comprehensive overview of the recent advances in material development and application, giving special attention to preparation methods, tunning of physiochemical properties, surface and interface chemistry, structural porosity, assemblies integration for fabrication of devices, and their relationship with overall efficiency. It offers a valuable reference guide for environmental and materials scientists, engineers, and policymakers working towards environmental sustainability.
Dr Neeraj Kumar is a researcher at Council for Scientific and Industrial Research (CSIR), Pretoria, South Africa. He is also visiting researcher in the Department of Chemical Sciences at the University of Johannesburg. He obtained his Ph.D. degree in chemistry from the University of Johannesburg in 2017. His research interests are in the synthesis and processing of carbon and inorganic nanostructured materials and their nanocomposites for energy and environmental sustainability. His current research focuses on developing 2D nanomaterials such as graphene, transition metal dichalcogenides (viz. MoS2), MXenes, g-C3N4, h-BN and 2D MOFs for environmental applications, including water and wastewater treatments, adsorption, photocatalysis, electrocatalysis, clean fuels and CO2 capture and utilization.
Dr Rashi Gusain received her Ph.D. degree in Chemical Science from CSIR-Indian Institute of Petroleum, India. In 2016, she started her first Postdoc at the Indian Institute of Technology Madras, India and later, she joined the group of Prof. Oleg Antzutkin at Luleå University of Technology, Sweden. Currently, she is working with Prof. Suprakas Sinha Ray at the University of Johannesburg and also a visiting researcher at CSIR-Pretoria. Her expertise is in organic and inorganic synthesis, ionic liquids, nanomaterials, tribology, photocatalysis, CO2 capture and conversion and water purification. Her current research interest is the development of inorganic materials for photo-degradation of organic water contaminants and CO2 capture and conversion.
