Simultaneous Production of CH4and H2from Photocatalytic Reforming of Glucose Aqueous Solution on Sulfated Pd-TiO2Catalysts

Abstract: -In this work, the simultaneous production of CH 4 and H 2 from photocatalytic reforming of glucose aqueous solution on Pd-TiO 2 catalysts under UV light irradiation by Light-Emitting Diodes (LED) was investigated. The Pd-TiO 2 catalysts were prepared by the photodeposition method. The Pd content was in the range 0.5-2 wt% and a photodeposition time in the range 15-120 min was used. Pd-TiO 2 powders were extensively characterized by X-Ray Diffraction (XRD), S BET , X-Ray Fluorescence spectrometry (XRF), UV-Vis… Show more

“…Biomass PR Beyond H 2 Generation Thel ow market value of H 2 renders alternative PR products desirable and, consequently,t he selective photocatalytic transformation of renewable feedstocks into valuable organic products is af ield of intense research. [56] The radical nature of glucose PR over M/TiO 2 gives rise to an umber of trace by-products such as CO, [12e,14] CH 4 , [14,19,22] formic acid [16] and others. [19] PR of cellulose or raw biomass over Pt/TiO 2 generated traces of C 2 H 6 ,e thanol and acetone.…”

“…When the load of catalyst was increased from to 12 g/L, the discoloration and the mineralization of the dye decreased. Possibly, the increase in the catalyst dosage over the optimum value resulted in a decreased light penetration through the solution because of the increased opacity of the aqueous suspension [22].…”
