Ag quantum dots modified hierarchically porous and defective TiO2 nanoparticles for improved photocatalytic CO2 reduction

Role of Oil Palm Empty Fruit Bunch-Derived Cellulose in Improving the Sonocatalytic Activity of Silver-Doped Titanium Dioxide

“…It was reported that large BET surface area was beneficial for the dispersion of active species (i.e., low valance Ti species and oxygen vacancies) and allowed higher exposure to the organic dye adsorption followed by oxidation [ 49 ]. The larger mesopores would also accelerate the diffusion of reactants and products, which contributed to higher catalytic performance.…”

Solar fuels: research and development strategies to accelerate photocatalytic CO2 conversion into hydrocarbon fuels

“…These can act as electron traps that facilitate electron-hole separation and ultimately improve the photocatalytic activity of semiconductor materials. 120 In particular, noble-metal cocatalysts, such as copper (Cu), 121 gold (Au), 122 silver (Ag), 123 palladium (Pd), 124 and rhenium (Rh), 125 can enhance photocatalytic conversion. For example, Biswas and co-workers developed Pt-TiO 2 nanostructured films using a gas-phase deposition method and examined the correlation between the size of the Pt nanoparticles (NPs) and photocatalytic activity (Fig.…”

Light-driven carbon dioxide reduction over the Ag-decorated modified TS-1 zeolite

“…with localized surface plasmon resonance (SPR) effects show great potential in the reduction of CO 2 , 21,22 which greatly improves the light absorption performance and the separation efficiency of photogenerated charges of semiconductors. 12,[22][23][24][25] In particular, in metal oxide catalytic systems, semiconductors with wide bandgaps can be regarded as the hot hole collectors, leaving a large number of hot electrons on the surface of the metal for the reduction of CO 2 . Besides, the Schottky junction formed at the interface between the metal and semiconductor could capture photogenerated electrons, greatly promoting the separation of photoinduced carriers.…”
