Cu-plated hollow glass microspheres for hydrogen production and degradation

Enhancement of hydrogen production of a Cu–TiO2nanocomposite photocatalyst combined with broad spectrum absorption sensitizer Erythrosin B

“…16 Incorporation of metals nanoparticles (NPs) as a co-catalyst is an effective method to improve photocatalytic activity. [17][18][19][20] It is reported that copper NPs have drawn much attention because they can enhance the photocatalytic activity by preventing photoexcited electron-hole recombination and surface plasmon resonance (SPR) effect of Cu NPs. [21][22][23][24][25] During past years, dye sensitization had been an effective method to convert long wavelength light to energy for photocatalyst in photocatalytic reaction.…”

Preparation and visible-light photocatalytic properties of the floating hollow glass microspheres – TiO2/Ag3PO4 composites

“…The main component of the hollow glass microspheres is soda lime borosilicate. 33 It can be clearly seen from Fig. 3 that the elements of HGMs-1 : 1.5 sample contained B, O, Na, Ca, Si originally contained in the HGMs.…”

Morphology‐controlled Electrodeposition of Copper Nanospheres onto FTO for Enhanced Photocatalytic Hydrogen Production

“…Photocatalytic hydrogen evolution of the obtained Cu/FTO samples was performed in a LabSolar III photocatalytic hydrogen evolution system (Perfectlight, Beijing) as our previous work. [28,31] A Xe lamp (300 W, PLS-SXE300CUV, Perfect Light Co. Ltd., Beijing) was applied as the light source. In a typical photocatalytic H 2 production experiment, Cu/FTO was immersed in an aqueous solution (70 mL) containing 60 mL of water and 10 mL of lactic acid as an electron sacrificial agent (pH＝6.40).…”

“…[30] Then, in order to prevent the aggregation, we loaded copper nanoparticles on the surface of HGMs by electroless plating technique to improve the photocatalytic efficiency. [31] Nevertheless, the amount, evenness and morphology of loaded nanoparticles are difficult to control by this method. Since the frequency of the surface plasmon absorption is highly dependent on the size and morphology of the metal nanostructures, the morphology-controlled synthesis of plasmonic metallic nanostructures with different shapes and sizes becomes very important.…”
