As the natural-born photoelectrolyzer for oxygen delivery, photosystem II (PSII) is hardly replicated with man-made constructs. However, building on the “quantasome” hypothesis ( 17811607 Science 1964 144 1009 1011 ), PSII mimicry can be pared down to essentials by shaping a photocatalytic ensemble (from the Greek term ”soma” = body) where visible-light quanta trigger water oxidation. PSII-inspired quantasomes (QS) readily self-assemble into hierarchical photosynthetic nanostacks, made of bis-cationic perylenebisimides (PBI 2+ ) as chromophores and deca-anionic tetraruthenate polyoxometalates (Ru 4 POM) as water oxidation catalysts ( 30510216 Nat. Chem. 2019 11 146 153 ). A combined supramolecular and click-chemistry strategy is used herein to interlock the PBI-QS with tetraethylene glycol (TEG) cross-linkers, yielding QS-TEG lock with increased water solvation, controlled growth, and up to a 340% enhancement of the oxygenic photocurrent compared to the first generation QS, as probed on 3D-inverse opal indium tin oxide electrodes at 8.5 sun irradiance (λ > 450 nm, 1.28 V vs RHE applied bias, TOF max = 0.096 ± 0.005 s –1 , FE O2 > 95%). Action spectra, catalyst mass-activity, light-management, photoelectrochemical impedance spectroscopy (PEIS) together with Raman mapping of TEG-templated hydration shells point to a key role of the cross-linked PBI/Ru 4 POM nanoarrays, where the interplay of hydrophilic/hydrophobic domains is reminiscent of PSII-rich natural thylakoids.

Recently, the weather has experienced changes and these have affected our life style. Fossil fuels used by the human have contributed to climate change and today it is impossible to modify. Researchers have studied different kind of fuels that could use daily. Currently, hydrogen, from water splitting, is the best way to substitute the fossil fuels because water is present around the World. In photoelectrochemistry, the electrodes have a great importance. Behaviour of each semiconductor as , , , , , , , etc., give us individual efficiency respect to solar light. Also, the semiconductor chosen, type of crystallinity and superficial area are important points for achieve high in efficiency. This review shows that inverse opal has a greater contact compared to rod, cauliflower, nanotubes, etc. Different ways to deposit the polystyrene allows us gain more contact area and better photoelectrode efficiency. The main routes used to obtain binary oxides deposits, as electrophoretic, spin coating, vertical submersion, etc., help us to control polystyrene arrangement and obtain a uniform template. These techniques are discussed along this contribution. Resumen. Recientemente, el clima ha experimentado cambios que han afectado a nuestro estilo de vida. Los combustibles fósiles utilizados por el ser humano han contribuido al cambio climático y hoy es imposible modificarlo. Los investigadores estudian diferentes tipos de combustibles que podrían utilizarse diaria y actualmente, el hidrógeno, a partir de la ruptura de la molécula de agua, es la mejor manera de sustituir los combustibles fósiles porque el agua está presente en todo el mundo. En fotoelectroquímica, los electrodos tienen una gran importancia. El comportamiento de cada semiconductor como TiO2, Fe2O3, NiO, CuO, NiS, ZnO, Cu2O, etc., tiene cada uno una eficiencia individual respecto a la luz solar que reciben. Además, del semiconductor elegido, el tipo de cristalinidad y el área superficial de este son puntos determinantes para alcanzar un alto grado de eficiencia. La presente revisión muestra que el ópalo inverso tiene un mayor contacto y eficiencia en comparación con las varillas, la coliflor, los nanotubos, etc. Diferentes formas de depositar el poliestireno como molde nos permiten obtener mayor área de contacto y mejor eficiencia del fotoelectrodo semiconductor. Las principales vías utilizadas para obtener depósitos de óxidos binarios, como electroforesis vertical, etc., nos ayudan a controlar la disposición del poliestireno y obtener una capa uniforme. Estas técnicas se discuten a lo largo de esta contribución.

“…Even more importantly, it is observed that the enhancement is increased about 2-fold in comparison of the THG intensity by incorporation of the ITO nanocrystals. In addition to THG, it has been recently observed that the ITO has been found various applications in different areas such plasmon-enhanced infrared spectroscopy, nanowire network and optoelectronics [24][25][26].…”

Optical nanoantennas have attracted a lot of research interest over the last decade owing to their unique characteristics in concentrating far-field radiation into the sub-wavelength dimensions. Also, they have been recently utilized to enhance the functionality of nonlinear optical devices. By inserting a dielectric nanoparticle within the gap of a dipole nanoantenna, the third-harmonic generation (THG) emission can be boosted. In this study, we simulate dipole and bowtie nanoantennas and compare their THG output spectra with and without the presence of indium tin oxide (ITO) nanocrystal in the nanoantennas gap. The results show that with proper design of the nanoantenna and changing the geometry from the dipole to the bowtie shape as well as inserting the ITO nanocrystal, the THG efficiency can be enhanced by a factor of three, which is higher than the dipole counterpart reported in recent established works. Our work opens a new window to generate more efficient nonlinear phenomena at nanoscale devices.
