ENHANCEMENT EFFECT OF LASER ABLATION IN LIQUID ON HYDROGEN PRODUCTION USING TITANIUM(IV) OXIDE AND GRAPHITE SILICA

摘要

Photocatalytic hydrogen production from methanol solution containing mixture of TiO2 and graphite silica (GS) was enhanced by the laser ablation in liquid. Addition of TiO2 to lased GS increased the amount of hydrogen gas evolved two times as large as that of GS-TiO2 mixture. This may be attributed mainly to the aggregation of TiO2 and GS fined by the laser ablation.
