Cesium

During 2022, no primary cesium mine production was reported globally but cesium was thought to have been mined in China. Mine production of cesium from all countries, excluding China, ceased within the past two decades. Mining of cesium in Namibia ceased in the early 2000s. Potential extraction of cesium from pollucite mining at the Tanco

Herein, a non-etching activation strategy is demonstrated using cesium salts of low-cost carboxylic acids as the sole precursor in producing porous carbons with yields of up to 25% and SSAs reaching 3008 m 2 g −1. The pore size and oxygen content can be adjusted by tuning the synthesis temperature or changing the molecular precursor.
