| Summary: | Carbon nanomaterials confined with metallic single-atoms have shown great potential in electrocatalysis because of their unique physicochemical properties such as high-efficiency, high mass activity and maximum atom-utilization for reactions involved in electrochemical energy conversion and storage, such as oxygen reduction, oxygen evolution, and hydrogen evolution reactions. In principle, metal single-atoms dispersed on appropriate carbon support ideally possess tunable coordination environment and unique electronic properties that result in excellent activity and selectivity toward catalytic reactions as compared to nanoparticles/or bulk form of noble and non-noble metals. This article reviews the recent advances of metal single-atom confined carbon nanomaterials, following their rational design strategies and correlation between metal-support combinations for the electrocatalysis of oxygen reduction, oxygen evolution, and hydrogen evolution reactions, including bifunctional activities for metal-air batteries and water electrolysis. A perspective on emerging fields of single-atom catalysis is also provided in this study.
Recent advances of single-atom-based carbon nanomaterials for the ORR, OER, HER, and bifunctional electrocatalysis are covered in this review article. |

| Bibliography: | magna cum laude After spending eight months as a postdoctoral Max Planck Fellow at the Physics Department of the Technical University Munich, he returned to Brazil. Between 2005 and 2007 he worked as a Group Leader (Jovem Pesquisador FAPESP) at ICSC/USP, and in 2007 was appointed Assistant Professor in the Physical Chemistry Department of the same Institution. In 2012 he became Associate Professor and in 2017, he became a Full Professor of Physical Chemistry at ICSC/USP. From the scientific point of view, Dr. Varela is currently interested in the following topics: electrochemical energy conversion, electrocatalysis, and self-organization in physical-chemical systems. Dr. Varela helped to establish the Ertl Center for Electrochemistry and Catalysis, at the Gwangju Institute of Science and Technology (GIST, Gwangju, Republic of Korea), where he is also Adjunct Professor at the School of Earth Sciences and Environmental Engineering. Hamilton Varela (1973) obtained his Bachelors degree in Chemical Engineering at Universidade Federal do Rio Grande do Norte, Natal, in 1997, and obtained his Masters degree in Physical Chemistry at the Institute of Chemistry of São Carlos of the University of São Paulo (ICSC/USP), São Carlos, in 2000. From 2000 to 2003 he did his Ph.D. with Professor K. Krischer at the Physical Chemistry Department (headed by Prof. G. Ertl, Nobel Laureate in Chemistry, 2007) - Fritz Haber Institut der Max Planck Gesellschaft, Berlin. His thesis was entitled "Spatiotemporal Pattern Formation during Electrochemical Oxidation of Hydrogen on Platinum", and was presented in 2003 at the Freie Universität Berlin, and he obtained the final mark Prerna A. Bhardwaj received her M.Sc. honors (2008) and Ph.D. (2014) in Chemistry from Panjab University, India. She worked at the University of Hohenheim, Germany as a Research Assistant. Her research mainly focuses on conducting polymers and their sensor applications, along with carbon nanomaterials as superconductors. Mohd. Khalid obtained his Ph.D. in Applied Chemistry in 2010 from Aligarh Muslim University, India. In 2011, he was awarded the Dr. D. S. Kothari postdoctoral fellowship from UGC, Govt. of India, at Panjab University Chandigarh. Later he moved to the Federal University of Santa Catarina, Florianopolis, Brazil and Case Western Reserve University, Cleveland OH, USA, where he worked as a postdoctoral fellow. Currently, he is a postdoc at the Institute of Chemistry of São Carlos, University of São Paulo. His research interests focus on carbon nanostructured materials for energy conversion and storage. Ana M. B. Honorato obtained her Bachelor degree in Physics in 2011 and a Master degree in Mechanical Engineering in 2013 from the Federal University of Santa Catarina, Florianopolis, Brazil. Currently, she is a Ph.D. student at Case Western Reserve University, Cleveland OH, USA, and Federal University São Carlos, Brazil, under the research program of CWRU-CAPES. Her research interests are carbon-based nanomaterials and conducting polymers for energy conversion and storage. |
