Sacrifice and valorization of biomass to realize energy exploitation and transformation in a photoelectrochemical way

Abstract

Photoelectrochemistry (PEC) transfers photoexcited electrons from the photocatalyst to the cathode through a wire, to avoid, to a considerable extent, the recombination of charge carriers in solitary photocatalysis. The moderate...

Rational Design of Photoanodes to Produce Value‐Added Chemicals Coupled with Hydrogen

“…However, some biomasses have a less positive oxidizing potential than water. [199] TiO 2 is a basic example of a suitable semiconductor for the PEC oxidation of biomass via * OH radical generation, but its insufficient light absorption limits its applications. [200,201] Figure 7 shows a schematic of the design of suitable photoanodes, considering their band positions for biomass oxidation or waste reforming via the PEC process.…”

Heterogeneous photocatalytic valorization of lignocellulose biomass for chemical and fuel production via reductive pathways

“…128,129 PEC techniques use light to create electron–hole pairs in semiconductors, driving reactions at the electrode surface that convert biomass into hydrogen and hydrocarbons using solar energy with high selectivity. 130,131 Photosonothermal techniques combine light, ultrasound, and thermal energy. Ultrasound's cavitation effect creates localized high temperatures and pressures, enhancing biomass degradation and catalytic processes for biofuel and chemical production.…”
