Photocatalytic Reduction of Carbonate Ions: Use of Safranine-O

Dr. Jyoti Bharadwaj, Dr. Paras Ram Teli

Abstract: Photochemical reduction of sodium carbonate was investigated in presence of safranine-O. The progress of the reaction was observed spectrophotometrically at dmax = 410 m. The effect of pH variation on the formation of formaldehyde and formic acid was investigated. Where two maxima were observed i. e. pH = 6.0 and 10.0. Effect of various other parameter like concentration of carbonate intensity of light etc. The rate of photocatalytic reduction was also studied. One of the most important and vital requirement of the society is energy since the ancient period. Here solar energy and photoreduction of carbonate ions entered the scene. Photocatalysis was number of application like solar energy conversion, synthesis of energy rich products etc. Recently in this field, Ortelli et al. Synthesized methanol and observed the reaction pathway for conversion CO and CO2 over a CuZr based catalyst while Nerlov et al. studied the influence of CO on the methanol synthesis from CO2 and H2 on Cu (100) catalyst. Shen et al.3 reported the impact of palladium precursors on the catalystic behaviour of Pd/CeO2 catalysts for the production of methanol from the hydrogenation of CO. Furuya and Hoide et al.4 studied the electrochemical reduction of CO2 using different metal electrode. Arakawa et al.5 used a RuS2/SiO2 photocatalyst. Calzaferri et al.6 also used volites as a porous carrier material Tryk et al.7 noted complete water splitting into H2 and O2 by using microheterogeneous semiconductor system in solar irradiation Kim et al.8 produced hydrogen from the decomposition of methane by domestic activated carbons. Liguras et al.9 reported that the production of hydrogen is possible during the partial oxidation of ethanol using R4 as a catalyst.
