Abstract
The adsorption attributes of methyl naphthalene and naphthalene molecules on P-Germanane sheets are explored based on the density functional theory method. The novel P-Germanane stability is established based on formation energy and phonon band spectrum. The stable P-Germanane exhibits a band gap of 3.944 eV. The calculated adsorption energy infers that methyl naphthalene and naphthalene are physisorbed on P-Germanane sheets. The charge transfer reveals that P-Germanane sheets behave as donors of electrons and target molecules behave as acceptors. The electronic attributes of P-Germanane sheets get altered owing to methyl naphthalene and naphthalene adsorption inferred from the band structure, PDOS spectrum, and electron density difference diagrams. We identified global minima position upon adsorption of 1-methylnaphthalene, and naphthalene on P-Germanane, which are named as bridge, octal, and tetra sites and adsorption attributes are explored in these sites. The adsorption energy and relative energy gap variation are noticed to be maximum for tetra site orientation of naphthalene on P-Germanane. The outcome exposes that P-Germanane sheets can be used as adsorption substrates for the detection of methyl naphthalene and naphthalene molecules.
期刊介绍:
Structural Chemistry is an international forum for the publication of peer-reviewed original research papers that cover the condensed and gaseous states of matter and involve numerous techniques for the determination of structure and energetics, their results, and the conclusions derived from these studies. The journal overcomes the unnatural separation in the current literature among the areas of structure determination, energetics, and applications, as well as builds a bridge to other chemical disciplines. Ist comprehensive coverage encompasses broad discussion of results, observation of relationships among various properties, and the description and application of structure and energy information in all domains of chemistry.
We welcome the broadest range of accounts of research in structural chemistry involving the discussion of methodologies and structures,experimental, theoretical, and computational, and their combinations. We encourage discussions of structural information collected for their chemicaland biological significance.
