The influence of the sacrificial agent nature on transformations of the Zn(OH)₂/Cd_0.3Zn_0.7S photocatalyst during hydrogen production under visible light

Abstract

The nature of the sacrificial agent affects the transformations of a Zn(OH)2 co-catalyst during photocatalytic hydrogen production.

Hydrogen Production from Water Splitting with 2,4,6-Triphenylpyrylium Modified on B-Doped N-Deficient Carbon Nitride Nanostructures

“…Raman spectra provide information about the skeleton structure of the samples. It is observed a broad band in the range of 1100–1750 cm –1 and three sharp signals at 707, 765, and 974 cm –1 , which are associated with C–N stacking vibrations, bending vibration of the C–NC linked heptazine linkages, and the symmetric N-breathing mode of the heptazine units, respectively (see Figure S1).…”

“…As illustrated in Figure D, the average lifetimes of the excited states of CN, BCN, and BCN-TPP are 2.48 ± 0.45, 2.31 ± 0.40, and 2.13 ± 0.38 ns, respectively. This reduction in a lifetime implies efficient photoinduced charge carriers and their fast transport and separation. , …”

Enhanced Charge Separation in a PAN/ZnO Nanocomposite for Promoted Photocatalytic Hydrogen Evolution

“…43,44 However, the research on photocatalytic hydrogen production by PAN is very limited, introducing a unique approach to the design of photocatalysts for efficient hydrogen generation. 45 In this work, a PAN/ZnO photocatalyst was synthesized by ultrasound-assisted agitation in DMF. The successful synthesis of the novel photocatalyst resulted in an enhanced photocatalytic performance through augmenting the efficiency of separating photogenerated electron−hole pairs while increasing the specific surface area.…”
