“…The parameter estimation problem begins with typical values for the adsorption parameter values for organic compounds on a catalyst based on TiO 2 , , . For those parameters for which there is no information about adsorption parameters, the initial parameters are supposed to have a typical order of magnitude.…”

Reactions involved in photocatalytic hydrogen production through water splitting combined with a hole scavenger involve several stages that make kinetic analysis quite complicated. In the present work, a kinetic model for the photocatalytic production of hydrogen has been developed based on competitive adsorption, considering the photocatalytic decomposition of an organic molecule coupled to hydrolysis through photocatalytic water splitting. Parameter estimation is performed by using the Levenberg‐Marquardt method. Model validation results give an estimation of the strength of adsorption of acetol and the acetaldehyde.

“…Furthermore, the accumulation of organic compounds in the liquid phase can be followed by hydrogen formation by PR; produced organic compounds act as hole scavengers themselves in a PR reaction (Equation 9). This reaction is very likely to happen with methanol due to its reactivity compared to other C 1 compounds [105,106].…”

The development of sustainable yet efficient technologies to store solar light into high energy molecules, such as hydrocarbons and hydrogen, is a pivotal challenge in 21st century society. In the field of photocatalysis, a wide variety of chemical routes can be pursued to obtain solar fuels but the two most promising are carbon dioxide photoreduction and photoreforming of biomass-derived substrates. Despite their great potentialities, these technologies still need to be improved to represent a reliable alternative to traditional fuels, in terms of both catalyst design and photoreactor engineering. This review highlights the chemical fundamentals of different photocatalytic reactions for solar fuels production and provides a mechanistic insight on proposed reaction pathways. Also, possible cutting-edge strategies to obtain solar fuels are reported, focusing on how the chemical bases of the investigated reaction affect experimental choices.
