Recent experiments have shown that microporous gold can be obtained via the oxidative dealloying of Au(Ag)-tellurides such as calaverite (AuTe 2 ), krennerite (Au 3 AgTe 8 ), and sylvanite [(Au,Ag) 2 Te 4 ] under mild hydrothermal conditions. The same Au textures have been found in natural gold-tell...
