摘要: The increase in the amount of carbon dioxide (CO2) emissions related to many anthropic activities is a persistent and growing problem. During last years, solutions have been set out, none them being ultimate one. Investigators agree on need synergic approach problem, terms complementary methods sequestration that, combined with reduction production, will be able decrease concentration CO2 atmosphere. In this work, we explore use green reaction trap into stable crystalline phase (weddellite) resorting multidisciplinary approach. reduced precipitated as calcium oxalate through vitamin C sacrificial reductant. Calcium crystals obtained show startling good quality that increases their already great stability over wide chemical physical conditions' range.
