Low-cost photoreactors for highly photon/energy-efficient solar-driven synthesis

Is There a Discernible Photochemical Effect Beyond Heating for Visible Photon-Mediated NH3 Decomposition over Ru/Al2O3?

“…However, photocatalytic processes have technological drawbacks in comparison to thermal catalytic processes, most notably the limited light penetration depth that often limits the "useful" reactor volume and results in a heterogeneous photon flux distribution throughout the reactor. 5,6 Furthermore, photons are a costly energy source compared to the heat provided by the combustion of fossil fuels. 7 Nevertheless, photon-driven catalytic processes on supported metal nanoparticles have demonstrated high quantum yields and energy efficiencies for industrially relevant chemical conversions.…”

“…There has been a surge of interest in the use of metal nanoparticles on insulating oxides as photocatalysts. − Metal nanoparticle photocatalysts offer certain advantages compared to semiconductor photocatalysts due to their wavelength-tunable photon absorption and surfaces with electronic structures that are well suited to drive chemical conversions with low activation barriers. However, photocatalytic processes have technological drawbacks in comparison to thermal catalytic processes, most notably the limited light penetration depth that often limits the “useful” reactor volume and results in a heterogeneous photon flux distribution throughout the reactor. , Furthermore, photons are a costly energy source compared to the heat provided by the combustion of fossil fuels …”

Design of interfacial dual Schottky junctions to modulate charge transfer for enhanced piezo-assisted photocatalytic degradation RhB performances

“…1,2 The photocatalytic efficiency is still unsatisfactory in comparison to a semiconductor material for the fast charge recombination. 3,4 Different protocols including interface engineering, heteroatom doping, and cocatalyst deposition have been developed to promote the electron-hole separation. As has been reported, the photogenerated charge migration within the semiconductor catalyst can be regulated by the built in electric eld.…”
