Biomass gasification is a promising strategy to address energy and environmental challenges. In this study, boron-doping biochar-based catalysts (Ni-B/FRC) were synthesized via one-step pyrolysis method and applied to biomass gasification for H2-rich syngas. The effects of the steam-to-biomass (S/B) ratio and boron doping ratio on the catalytic performance were investigated. A higher S/B ratio improved H2 yield but accelerated catalyst mass loss. Boron doping enhanced the structural stability of biochar catalysts by forming COB linkages and B2O3 active sites, and improved nickel nanoparticle dispersion for better catalytic performance. The Ni-3B/FRC exhibited the lowest mass loss (7.7 %) and achieved a high H2 yield of 23.7 mmol/g. After five cycles, the Ni-3B/FRC maintained superior catalytic stability and a stable biochar structure. Therefore, boron-doping biochar-based catalyst is a low-cost, efficient and stable catalyst for hydrogen production from biomass gasification.

Hydroboration-Oxidation of Alkenes
Regioselectivity and Stereochemistry of Hydroboration
Hydroboration proceeds in a concerted fashion with the attack of borane on the π bond, giving a cyclic four-centered transition state. The –BH2 group is bonded to the less substituted carbon and –H to the more substituted carbon. The concerted nature requires the simultaneous addition of –H and –BH2 across the same face of the alkene giving syn stereochemistry.
Preparation of Alcohols via Addition Reactions
The acid-catalyzed addition of water to the double bond of alkenes is a large-scale industrial method used to synthesize low-molecular-weight alcohols. An acidic atmosphere is required to allow the hydrogen in the water molecule to act as an electrophile and attack the double bond in an alkene. The addition of a proton to the double bond creates a carbocation intermediate. The proton preferentially bonds to the less substituted end of the double bond to create a more stable carbocation...
Alkynes to Aldehydes and Ketones: Hydroboration-Oxidation
One of the convenient methods for the preparation of aldehydes and ketones is via hydration of alkynes. Hydroboration-oxidation of alkynes is an indirect hydration reaction in which an alkyne is treated with borane followed by oxidation with alkaline peroxide to form an enol that rapidly converts into an aldehyde or a ketone. Terminal alkynes form aldehydes, whereas internal alkynes give ketones as the final product.
Reduction of Alkynes to cis-Alkenes: Catalytic Hydrogenation
Like alkenes, alkynes can be reduced to alkanes in the presence of transition metal catalysts such as Pt, Pd, or Ni. The reaction involves two sequential syn additions of hydrogen via a cis-alkene intermediate.
Reduction of Alkenes: Asymmetric Catalytic Hydrogenation
The metal catalyst used can be either heterogeneous or homogeneous. When hydrogenation of an alkene generates a chiral center, a pair of enantiomeric products is expected to form. However, an enantiomeric excess of one of the products can be facilitated using an enantioselective reaction or an...
