Although the microbial and the photochemical methylation and demethylation processes are well studied in recent years but the chemical methylation and demethylation processes have not been studied well. Herein, we report for the first time that the CuSe nanosheet has remarkable ability to activate the highly inert Hg\u2212C bonds of various MeHg<jats:sup>+<\/jats:sup> and Me<jats:sub>2<\/jats:sub>Hg compounds at room temperature (21\u2009\u00b0C). It facilitates the conversion of MeHg<jats:sup>+<\/jats:sup> into Me<jats:sub>2<\/jats:sub>Hg in the absence of any proton donors. Whereas, in the presence of any proton source, it has unique ability to degrade MeHg<jats:sup>+<\/jats:sup> into CH<jats:sub>4<\/jats:sub> and inorganic mercury (Hg<jats:sup>2+<\/jats:sup>). Detailed studies revealed that the relatively fast Hg\u2212C bond cleavage was observed in case of MeHgSPh or MeHgI in comparison to MeHgCl, indicating that the Hg\u2212C bond in MeHgCl is relatively inert in nature. On the other hand, the Hg\u2212C bond in Me<jats:sub>2<\/jats:sub>Hg is considered to be exceedingly inert and, thus, difficult to cleave at room temperature. However, CuSe nanosheets showed unique ability to degrade Me<jats:sub>2<\/jats:sub>Hg into CH<jats:sub>4<\/jats:sub> and Hg<jats:sup>2+<\/jats:sup>, via the formation of MeHg<jats:sup>+<\/jats:sup>, under acidic conditions at room temperature. DFT calculations revealed that the Hg\u2212C bond activation occurs through adsorption on the surface of (100)\u2010faceted CuSe nanosheets.<\/jats:p>","DOI":"10.1002\/asia.201901077","type":"journal-article","created":{"date-parts":[[2019,10,1]],"date-time":"2019-10-01T13:01:58Z","timestamp":1569934918000},"page":"4582-4587","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":10,"title":["Chemical
