PROGRAM TOPIC: CARBON MANAGEMENT USING THE LOW-RANK COAL AS PHOTOCATALYSTS FOR CONVERSION OF CO_2 TO METHANOL

摘要

Photo-catalytic reduction is an increasingly important approach for transformation and utilization of carbon dioxide in recent year. In our research, a kind of low-rank coal (Shenfu coal, from Shaanxi province, China) first act as photo-catalyst in CO_2 conversion. Its photo-catalytic properties were evaluated by photo-catalytic reduction of CO_2 in 0.1 mol/L Na_2SO_3 and 0.1 mol/L 250ml NaOH aqueous solutions. The results showed that methanol yield was 137.65umol/L on 1 g/L Shenfu coal after 14 hours' irradiation time while methanol yield was only 38.72umol/L on TiO_2 at the same reaction condition.
