Source<\/strong>-This post on Development of Goldene<\/strong> is based on the article “GOLDENE: A sheet of gold that is only one atom thick”<\/strong> <\/a>published in \u201cThe Indian Express<\/strong>\u201d on 6th May 2024.<\/p>\n

Why in the News?<\/h2>\n

For the first time, scientists have successfully developed a free-standing, single-atom-thick sheet of gold. This marks the first instance of a metal being transformed into a 2D sheet. This breakthrough paves the way for numerous exciting opportunities in the future.<\/p>\n

About Goldene<\/strong><\/td>\nGoldene\u00a0is a\u00a02-dimensional allotrope of gold<\/span>, which means it consists of a single layer of gold atoms arranged in a two-dimensional structure.<\/td>\n<\/tr>\n
Unique features<\/strong><\/td>\n\u00a0i) It exhibits semiconductor properties\u00a0when fabricated into this single-atom-thick layer<\/span>.\u00a0Typically, gold is known for its excellent conductivity, but it behaves differently in its goldene form.
\nii) These sheets of goldene are roughly 100 nanometres thick<\/span> (a nanometre is a billionth of a metre), approximately 400 times thinner than the thinnest commercially available gold leaf.<\/td>\n<\/tr>\n
How is it created?<\/strong><\/td>\ni) Goldene has been created by first placing a single layer of silicon between titanium carbide layers.<\/span>
\nii) Then gold is added which diffused into the structure and replaced the silicon, forming a <\/span>monolayer of gold.<\/span>
\niii) This was done with the help of an age-old Japanese technique using chemical popularly known as<\/span> <\/span>Murakami\u2019s reagent.<\/span> This chemical is also used to forge katanas and high-quality knives.<\/td>\n<\/tr>\n
Potential applications<\/strong><\/td>\ni) Electronics Industry Revolution:<\/strong> Goldene ultra-thin and lightweight properties could significantly reduce the amount of gold needed in electronics.<\/span><\/span>
\nii) Catalysis:<\/strong> As a catalyst, goldene offers economic benefits over traditional three-dimensional gold<\/span> due to its efficiency and reduced material usage.<\/span> This could be useful in various chemical processes.<\/span><\/span>
\niii) Extension to Other Metals:<\/strong> The technique developed to create goldene could also be adapted to produce two-dimensional sheets of other precious metals<\/span><\/span> like iridium and platinum, expanding the range of applications.
\niv) Special Properties for Advanced Applications: <\/strong>Goldene has a unique structure where each atom connects to six others, not twelve. This could lead to specific uses in turning carbon dioxide into other materials, producing hydrogen, and purifying water.<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n
