“…The catalytic conversion of renewable biomass resources into clean and high-value-added chemicals has become one of the fundamental research topics for building a sustainable chemistry community. − Sorbitol, as an important industrially accessible biomass-derived platform molecule, finds wide applications as a food additive, lubricant in cosmetics, pharmaceuticals, and a building block for various biobased valuable products, including alkanes and polymers. − The catalytic hydrogenation of glucose represents a direct and reliable protocol for sorbitol production in the industry, with an annual production volume nearing 2 million tons . In the traditional industrial production process, this transformation is predominantly driven by the Raney Ni catalysts owing to the low cost and high accessibility of the Ni element.…”

Catalytic hydrogenation of carbohydrates over the Raney Ni catalyst is an important industrial process to produce valuable polyols. However, this process generally encounters challenges such as harsh reaction conditions, low catalytic activity, and catalyst deactivation. In this contribution, metallic nickel-rich nickel borides (NiBO-nKH2PO4) were successfully constructed via a simple chemical reduction method with potassium dihydrogen phosphate (KH2PO4) as the buffering agent and sodium borohydride (NaBH4) as the reducing reagent. Especially, the obtained NiBO-10KH2PO4 afforded quantitative sorbitol yield from the catalytic hydrogenation of glucose under mild reaction conditions within 1 h (80 °C and 1 MPa H2). Compared with the reported literature for the production of sorbitol from glucose, the developed NiBO-10KH2PO4 catalyst circumvents the use of a high hydrogen pressure and reaction temperature while delivering excellent catalytic performance and stability. Moreover, the experimental analysis demonstrated that the obtained nickel borides, with the assistance of KH2PO4, possessed abundant metallic nickel species, which favored the adsorption and activation of hydrogen molecules and thus largely promoted the hydrogenation of glucose. This work provides new insights into the rational design of practical nickel-based catalysts for the efficient catalytic hydrogenation of carbohydrates.

Hydrodeoxygenation (HDO) is regarded as a promising technology for biomass upgrading to obtain sustainable and competitive chemicals and fuels. In fact, biomass HDO over heterogeneous solid catalysts is often accompanied by the phenomenon of hydrogen spillover, which further affects the catalytic performance. Thus, it is necessary to gain in‐depth understand the promoting effect of hydrogen spillover in the biomass HDO process to obtain desired conversion and selectivity. This Review summarized the extensive research on hydrogen spillover in biomass refining and discussed in detail the regulation mechanism of hydrogen spillover in biomass HDO process, mainly by regulating different active center sites on catalyst supports, such as metal sites, acid sites, surface functional groups, and defective sites, which exhibit independent and synergistic characteristics promoting catalyst activity, selectivity, and stability. Finally, the prospective of hydrogen spillover in biomass HDO applications was critically evaluated, and the key technical challenges in developing “hydrogen‐free” HDO and upgrading biofuels were highlighted. The presentation of hydrogen spillover‐enhanced catalytic biomass HDO in this Review will hopefully provide insight and guidance for further development of efficient catalysts and preparation of high‐value chemicals in the future.
