“…(Lukatskaya et al 2013;Naguib et al 2012b;Mashtalir et al 2013;Khazaei et al 2013). They have important application in the areas such as electrode materials for Liion batteries (Tang et al 2012;Shein and Ivanovskii 2012;Lin et al 2015;Naguib et al 2012a) or supercapacitors (Lukatskaya et al 2013), catalysts (Gao et al 2014), and lead adsorption materials (Peng et al 2014). Especially, our group theoretically predicted that MXenes are promising hydrogen storage materials (Hu et al 2013.…”

MXene‐Based Composites: Synthesis and Applications in Rechargeable Batteries and Supercapacitors

“…[159] Afterward, CNFs, originating from the carbonaceous gas, can be deposited on the Ti 3 C 2 T x surface by a CVD method using the Co catalysis. [71] The unique 3D network structure of the fiber material leads to the presence of a large number of voids. Both ends of a CNF link with two layers of the Ti 3 C 2 T x film so that the Ti 3 C 2 T x films can retain their open frameworks.…”

“…The CNFs contain numerous electron holes, which boosts the performance of Ti 3 C 2 T x films. [71] Alternating filtration [155] is the most straightforward method to synthesize the MXene-carbon nanoparticle composites. Moreover, the CNF can link with further Ti 3 C 2 T x film via its long chain lengths.…”
