PtNi Alloy Cocatalyst Modification of Eosin Y-Sensitized g-C3N4/GO Hybrid for Efficient Visible-Light Photocatalytic Hydrogen Evolution
An economic and effective Pt-based alloy cocatalyst has attracted considerable attention due to their excellent catalytic activity and reducing Pt usage. In this study, PtNi alloy cocatalyst was successfully decorated on the g-C3N4/GO hybrid photocatalyst via a facile chemical reduction method. The Eosin Y-sensitized g-C3N4/PtNi/GO-0.5% composite photocatalyst yields about 1.54 and 1178 times h...
متن کاملNanotitania composite assembled with Graphene oxide for Photocatalytic degradation of Eosin Yellow under Visible light
Visible light responsive Graphene oxide (GO) nanotitania composite was synthesized and its photocatalytic activity was investigated for the degradation of Eosin Yellow (EY). The nanocomposite was synthesized by organic solvent free-controlled hydrolysis of titanium tetrachloride (TiCl4) exfoliated with 10 wt. % (0.5 g) of the as prepared GO particles under ultrasonication through in-situ additi...
متن کاملPhotocatalytic hydrogen production from water under visible light irradiation using a dye-sensitized attapulgite nanocrystal photocatalyst.
Attapulgite (ATP), not only as a type of natural and low cost silicate clay mineral but also as a high quality nanosized material with large surface area, layered and lath-like structure, has been found to have a wide variety of industrial applications. The ideal composition of ATP is Mg5Si8O20(OH)2(OH2)4. However, according to previous reports from different countries in the world, it is very ...
متن کاملEosin Y-sensitized artificial photosynthesis by highly efficient visible-light-driven regeneration of nicotinamide cofactor.
Dye-sensitized photosynthesis: Eosin Y (EY), a dye photosensitizer, works efficiently as a molecular photoelectrode by catalyzing the visible-light-driven electron-transfer reaction for efficient regeneration of NADH through a photosensitizer-electron relay dyad. Injection of the photosensitized electron resulted in highly accelerated regeneration of NADH, which can be used by glutamate dehydro...
متن کاملEnhancement of photocatalytic H2 evolution of eosin Y-sensitized reduced graphene oxide through a simple photoreaction
A graphene oxide (GO) solution was irradiated by a Xenon lamp to form reduced graphene oxide (RGO). After irradiation, the epoxy, the carbonyl and the hydroxy groups are gradually removed from GO, resulting in an increase of sp(2) π-conjugated domains and defect carbons with holes for the formed RGO. The RGO conductivity increases due to the restoration of sp(2) π-conjugated domains. The photoc...
