“…The Si (2p) deconvoluted spectra contains bands with binding energy values corresponding to Si-OÀ Si (102.7 eV) and Si-OH (103.8 eV) for WCHA and SiÀ C (101.7 eV), Si-OÀ C (102.1 eV), Si-OÀ Si (102.9 eV) and Si-OH (103.7 eV) for WCHA-TG30. [57][58][59][60][61] The O (1 s) spectra of WCHA is characterized by various oxygen functionalities such as that in MgO (530.1 eV), 2À and aromatic π-π* interaction in graphene layers respectively. [56][57][58][59][60][61][62][63][64] Thus deconvoluted spectra of each element in the composite WCHA-TG30 confirmed the binding between graphene layers and CHA particles.…”

Herein we report an easy, scalable, cost‐effective and green synthesis of twisted graphene from bulk graphite by a ball milling technique with the in situ formation of novel coconut husk ash (CHA) ‐ twisted graphene nanocomposite and its catalytic application towards multicomponent Biginelli reaction. Here the ash derived from naturally available waste material (coconut husk) is effectively used as an exfoliating agent for the scissoring of graphene layers from bulk graphite for the first time. The elemental analysis data obtained by inductively coupled plasma atomic emission spectroscopy (ICP‐AES) provided useful information regarding the composition of CHA and the nanocomposites. The X‐ray diffraction (XRD) patterns confirmed the exfoliation of graphite into graphene layers. Raman spectroscopic analysis evaluated the quality and the nature of graphene layers in the composites. X‐ray photoelectron spectroscopy (XPS) analysis confirmed the bonding between the graphene layers and CHA particles. Transmission electron microscopy (TEM) images revealed the presence of few layered graphene as well as twisted graphene in the composites. The CHA – twisted graphene nanocomposite is found to be an excellent reusable catalyst for Biginelli reaction with a higher yield of 3,4‐dihydropyrimidinones within short duration of reaction.

“…(Dong et al, 2011;Tang et al, 2013;Zhang et al, 2014;Li et al, 2015). Specifically, clay minerals have been widely used as a supporting material for the development of hybrid nanomaterials, due to the quality of these silicates to assemble with different types of active species at nanoscale levels (Son et al, 2010;Burridge et al, 2011;Křišt'an et al, 2013;Cristina et al, 2014;Dutta and Dutta, 2014;Mart'ınez et al, 2015). Sepiolite possess large surface area and porosity as well as fibrous one-dimensional (1D) structure (Suarez et al, 2009).…”

“…Over the years, nanoparticles and high performance nanostructured materials have attracted growing interest from both fundamental and applied research communities (Burridge et al, 2011). This is due to nanoparticles having a much higher specific surface area (Zuber et al, 2010) and a higher concentration of atoms in interfacial locations than larger particles of similar composition (Baláž et al, 2004;Jeon and Baek, 2010).…”
