Research progress on metal oxide oxygen carrier materials for two-step solar thermochemical cycles in the last five years

Light-assisted thermochemical reduction of CuFe2O4 within a photo-thermogravimetric analyser for solar fuel production

“…Wu et al [31] demonstrated the obvious impact of the quantity and quality of photo-induced V O s in V O -based reactions, and reported a two-step V O -based reaction on Ni/Cu-TiO 2 with H 2 yield of 27.01 µmol g −1 . Current photo-thermochemical cycles showcased the superiority of mild operating temperatures, but the solar fuel production remained low yield compared with conventional thermochemical cycles [34]. The effects of several key factors, such as temperature, light intensity and spectral ranges of light illumination, on non-thermal effects still need investigation [30].…”
