**Preface to "Nanocomposites for Environmental and Energy Applications"**

The exploration of various functional nanocomposite has offered vast opportunities in addressing global-scale environmental and energy issues. Over the last decade, tremendous efforts have been made in harnessing the potentials of nanocomposite through their novel synthesis and innovative applications. This Special Issue compiles a total of 9 review and research articles that deal with state-of-the-art development in nanocomposite materials for environmental and energy applications. The applications of nanocomposites in environmental remediation such as heavy metal removal and photocatalytic reaction as well as in energy applications such as supercapacitor and batteries are some of the highlights presented in this Special Issue.
