Formic acid was employed for the nitrate reduction as a reductant in the presence of the alumina supported bimetallic Pd:Cu catalysts. Almost 100% nitrogen conversion of nitrate was due to the in situ buffering effect of CO2, which formed by the decomposition of formic acid on the surface of catalyst. To prevent formic acid from being left and to control the nitrate concentration below regulation at the same time, formic acid was used as a limiting reagent. The pH control by formic acid itself was not enough to ensure the maximum reduction efficacy of this system and additional pH control was necessary to achieve the goal. Our result shows that formic acid can convert the nitrate into nitrogen without producing the detectable amount of nitrite and ammonia and no formic acid remained after the treatment.
