Direct Electrochemical Reduction of Bicarbonate to Formate Using Tin Catalyst

Nowadays, the self-accelerating increase in global temperatures strengthens idea that cutting of CO2 emissions will not be enough to avoid climate change, thus from atmosphere must removed. This gas can easily trapped by converting it bicarbonate using hydroxide solutions. However, converted into a more valuable product make this technology profitable. Several studies show great efficiency when reducing solutions saturated with pure formate. those approaches don’t have real application and our objective was obtain similar results without saturation. The method consists electroreduction solution bulk tin (Sn) as catalysts. Tin is relatively cheap material that, according previous performed solutions, shows selectivity towards 1H NMR analysis after gas, faradic around 18% but almost 50% for ones. formate obtained could used power formate/formic acid fuel cells obtaining battery-like system, greater energy density than common lithium batteries, needs improved them competitive.
