In Situ Solid-State NMR Deciphering Dehydration Intermediates on TiO2 facets

Why does water inhibit alcohol dehydration rates more significantly on TiO2(001) than on TiO2(101)? 🧐Check out how in situ solid-state NMR deciphers this.#GlobalnmrOC2024 pic.twitter.com/AXyBKrOP4d

We used in situ 13𝐶-1𝐻 CP and 1𝐻 NMR to identify dehydration intermediates on TiO₂ facets. A water-isopropoxide complex on TiO₂(001) and a water-isopropanol complex on TiO₂(101) explain different dehydration rates, crucial for understanding biomass conversion mechanisms.
