WebAug 19, 2024 · The influence of dye absorption, the photoelectron transfer reaction between IOPF and dyes and sample thickness on the curing systems of E51 were studied, and discussion for further understanding the structure–property relationship were also involved. There are still few 510-nm photosensitizers for photopolymerization. WebIn this study, a sulfur (S)-mediated photodeposition method is adopted to precisely modify NiS cocatalyst at photoelectron transfer sites of BiVO4. Specifically, photoelectrons enrich enough concentration of Ni2+ ions on the (010) facet of BiVO4, where the S molecules combine with them to in situ form NiS and deposit on its surface.
