Photocatalytic H2 production from aqueous methanol solutions using metal-co-catalysed Zn2SnO4 nanostructures

Silver nanoparticles-sensitized cobalt complex for highly-efficient photocatalytic activity

“…A similar tendency was observed for samples 1-5, whose quantum yields (˚) are summarized in Table 1 [11,51]. Sample 3 gives a stronger fluorescence.…”

“…2a. According to control experiments, no H 2 generation is observed at the present of either a catalyst or illumination [51,57]. When using pure Co-2TPABTz as the photocatalyst, the rate of H 2 evolution was only 0.46 mmol h −1 g −1 ( Table 2) [13].…”

“…A slight red shift of the emission peak compared with Co-2TPABTz was mainly ascribed to the wrapping with Ag NPs quenching the fluorescence from Co-2TPABTz, the energy of emission light is reductive than that of Co-2TPABTz, and the charge carrier transformation between Co-2TPABTz and Ag NPs [75]. The lowest PL intensity was observed for the composite 3, suggesting that the Ag NPs photosensitizer helps the transfer of charge carriers and slows down the recombination process [51].…”

A Facile Approach for the Synthesis of Zn2SnO4/BiOBr Hybrid Nanocomposites with Improved Visible-Light Photocatalytic Performance

“…Moreover, the photodegradation of rhodamine B (RhB) [ 6 ], methyl blue [ 7 , 8 ], methyl orange [ 9 ], and direct black 38 azo-dye [ 10 ] was successfully achieved over ZTO nanostructured photocatalysts under UV irradiation. Besides these examples, as reported in the previous literature [ 11 ], the photocatalytic H 2 production from methanol solution was successfully accomplished using a ZTO nanostructured material as a photocatalyst under UV irradiation. Despite of the merits mentioned above, ZTO has a wide bandgap (~3.6 eV), leading to the fact that it can only absorb a small portion of the total irradiated natural sunlight.…”

“…Nowadays, photocatalysis is considered to be an effective and sustainable approach for resolving the disturbing issue of the energy crisis and environmental pollution. Owing to the high electrical conductivity and electron mobility [ 1 , 2 , 3 , 4 ], Zn 2 SnO 4 (ZTO) has been confirmed the diversity in the photodegradation of organic contaminants [ 5 , 6 , 7 , 8 , 9 , 10 ], the evolution of hydrogen from ethanol solution [ 11 ], and the reduction of CO 2 to CH 4 [ 12 ]. For instance, Lou et al demonstrated the photodegradation of three water-soluble organic dyes, using ZTO nanocrystals as photocatalyst under UV irradiation [ 5 ].…”
