An organic photovoltaic catalyst (Y6CO) with a central steric-hindrance-free carbonyl group, achieves efficient Pt 0 in situ deposition through σ-π anchoring, leading to significantly enhanced utilization of the Pt cocatalyst and photocatalytic hydrogen evolution of Y6CO/Pt based nanoparticles under simulated solar light illumination.
Solar energy catalysis is a specific and “all-in-one” definition for the kind of catalytic reactions that utilize solar light as the energy input.
With a heterogeneous catalyst, one of the major problems in the design and scale-up of a solar photoreactor is achieving uniform distribution of sunlight inside the reactor, due to absorption, reflection, and scattering effects by the catalyst particles or the supporting material.
Based on the different conversion pathways, solar energy catalysis can be divided into photocatalysis, photothermal catalysis, solar cell powered catalysis, pyroelectric catalysis, and the combined effect of some of these processes. When it comes to using solar energy to promote catalytic reactions, photocatalysis technology is the first choice.
For membrane catalysts, a circular membrane catalyst with a diameter of 6.5 cm was cut to replace the inorganic particulate photocatalyst and fixed in the closed glass photoreactor to perform the HTH conversion, and the membrane catalyst was impregnated 0.3 cm below the liquid level in photocatalytic process.
Design of solar photocatalytic reactors for commercial use Any industrial application of a photocatalytic process requires a photoreactor, that is, a specific device which can efficiently bring solar photons and chemical reagents into contact with the photocatalyst.
