One extremely promising approach for turning biomass into useful chemicals and fuels is hydrodeoxygenation (HDO). In the reaction of its platform chemicals, water can be used as a reactant or cocatalyst on one hand, thus significantly enhancing catalytic speed product selectivity. On other it green, nontoxic, inexpensive. Notably, also often reported destructive factor. Therefore, optimal functioning catalysts efficiently sustained by rationally utilizing physicochemical interaction between water. This study reviews regulation activity, selectivity, stability reactions using various (noble metal catalysts, transition etc.) in aqueous environment. The catalyst structure optimized adding particles, heteroatom doping modification, methods, which combine complementary effect to accomplish effect. further discussed, methods improve resistance deactivation are summarized. At last, perspectives put forth purpose advancing future development.

Hydrodeoxygenation (HDO) plays a crucial role in upgrading pyrolysis-oil derived from biomass. Here we describe method for fabricating carbon-encapsulated nickel metal-acid bifunctional catalyst (Ni@C/RCS-Al) supported on aluminum-doped radial channel silica (RCS-Al). This exhibits large surface area and highly dispersed accessible active sites, achieved through combination of salicylate- MOF-assisted strategies. The RCS-Al was prepared by one-pot salicylate-assisted hydrothermal an aqueous phase containing Al source, which is simple, has high yield, saves time. results show that Ni@C/RCS-Al displays well-defined pore structure with mesopore diameter 31.1 nm, can significantly increase the number sites accelerate mass transfer. strategy leads to formation smaller nanoparticle doping contributes adjustable acid demonstrating catalyst. Importantly, kinetics study revealed reaction constant constructed demonstrates remarkable performance HDO, achieving complete m-cresol conversion 100% selectivity target product methylcyclohexane within brief period 75 min. exceptional stems its optimization sites. thin carbon layer Ni superior stability water resistance, as verified experimental DFT calculations. work opens up new idea application silica-supported catalysts various reactions.
