Fabrication and Characterization of Functional Two dimensional Materials for Electrochemical Energy Conversion and Storage

Abstract

Chapter 1: As an introductory part, we have discussed the overview of the global scenario of newlineenergy conditions, the role of nanotechnology and nanomaterials, and the different newlinedimensionalities of materials. In addition, we have provided an overview of the water splitting and newlinesupercapacitor applications along with basic electrochemical measurement techniques. newlineChapter 2: This chapter briefly presents the literature review on the progress of 2D materials, newlineuseful equations involved in application studies, and characterization techniques. In addition, the newlinechapter also reveals the properties of graphene, TMDCs, and MXenes materials along with their newlinerecent progress in water splitting and supercapacitor applications. newlineChapter 3: It deals with the study of NiFe2O4 and graphene material for OER application, which newlineis further divided into two sections 3.1 and 3.2. newlineSection 3.1 illustrates the performance of NiFe2O4 with different carbon-based materials such as newlineSWCNT, MWCNT, and graphene. The effect on the OER activity of these carbon-based materials newlineis briefly discussed. newlineSection 3.2 discusses the effect of metal concentration tuning with graphene and its affection on newlinethe morphology of hybrid and OER activity. newlineChapter 4: In this chapter, the performance of TMDCs-based hybrids investigated towards HER, newlineOER, and supercapacitor application, which is presented in two sections 4.1 and 4.2. newlineSection 4.1 reveal the well-controlled and facile preparation of MoS2/NiFe2O4 hybrid materials by newlinehydrothermal method and its application in HER, OER as well as a supercapacitor. newline newlineXXIX newlineSection 4.2 shows the high performance of VS2-based ternary VS2/ZnS/CdS hybrid electrocatalyst newlinefor HER. newlineChapter 5: In this chapter, we designed metal oxide and metal telluride decorated MXene newlinenanosheets and studied their performance in the water-splitting application. This chapter is divided newlineinto two sections as follows: newlineSection 5.1 present the facile hydrothermal approach to decorating Ti3C2Tx nanosheets with newlinesemimetallic 1T MoTe2 materials. The prepared MoTe2/Ti3C2Tx hybrids reveal high HER newlineperformance. newlineSection 5.2 shows the designing and decoration of NiFe2O4 nanoparticles on 2D Ti3C2Tx MXene newlinesheets via a facile one-pot hydrothermal method. The NiFe2O4/Ti3C2Tx composite showed high newlineperformance towards both OER and HER reactions as compared to pristine NiFe2O4 nanoparticles newlineand Ti3C2Tx sheets. newlineChapter 6: This chapter presents the overall conclusions of the work reported in the thesis and newlinealso comments on the future scope of this study. newline
