“…[246] However, the large-scale implementation of this two-step approach (liquefaction and hydrodeoxygenation) still presents major concerns regarding the efficiency and costs, making the one-pot hydroliquefaction (or catalytic reductive depolymerization) more attractive. [247][248][249] In this scenario, FA and alcohols as H-donors plays a crucial role and exhaustive recent review articles thoroughly discussed their potential in high-quality bio-oil production.

consumption combined with a resource efficient circular economy approach, with the final goal of minimizing the impact of health, safety, security and environment.In the design of a greener future, the replacement of depleting sources with renewable ones is at the center of a sustainable development. [2] Biomass is a natural, abundant, renewable, carbon-neutral source; its use represents a promising strategy to address the need for substituting fossil feedstock in the preparation of chemicals, fuels, and materials, besides energy production. [3][4][5][6][7][8][9][10][11][12][13][14] The major issues that limit the large-scale utilization of biomass in fuel production are the differences in cost and process efficiencies compared to those for fossil fuels. [15] After the Covid-19 crisis, this aspect has become even more evident, as reported by the International Agency of Energy, ultimately causing the first contraction in biofuel production over the past two decades. [16] The reduced transport fuel demand and the decreased petroleum-based fuel prices have transitorily lowered the economic interest for biofuel production. In this pandemic and emergency scenario, therefore, has emerged even more clearly the importance of developing efficient strategies for biomass conversion into fuels, making economically attractive the use of environmentally friendly renewable energy systems (Figure 1). [17] Among the plethora of biomass transformations, hydrogenation and hydrodeoxygenation reactions are widely used for decreasing the oxygen content of biomass-derived platforms to increase their potential as fuels. [18][19][20] In this context, as well as in the challenging goal of creating a decarbonized energy system, hydrogen plays a prominent role in the chemical industry. [21][22][23][24] It is important to notice that the vast majority of the worldwide hydrogen production (45-65 Mt/year) features a significant CO 2 footprint as a consequence of different hydrocarbon reforming processes (i.e., steam-reforming of fossil fuels, thermal cracking of natural gas, solar-thermal reforming of methane) or of coal gasification. [25] Several efforts have been directed during the past years toward the definition of possible effective approaches to a green H 2 production by water splitting. [26][27][28][29][30][31] To date, however, both water electrolysis and photo-driven water splitting are economically and energetically unfavorable, with a long way ahead to hold the promise of a zero-carbon energy system. Indeed, the associated energy demand as well as the low market prices of oxygen, inevitably co-produced from water electrolysis, hinder the shaping of a large-scale employment of this technology.Liquid organic hydrogen carriers (LOHCs) are attractive materials for their ability to generate in situ hydrogen that may be directly used to produce target biofuel precursors, fuels or fuel additives. Indeed, the replacement of fossil feedstock is an urgent necessity for shifting toward a carbon neutral energy economy. Several desired chemica...

“…Because of its low toxicity, high hydrogen storage capacity, and availability from renewable resources, FA has recently attracted significant attention for its potential applications as a chemical hydrogen storage medium. 3 − 9 Some promising methods were reported for the conversion of renewable biomass or carbon dioxide (CO 2 ) into FA, such as acid hydrolysis of biomass, wet oxidation of biomass, catalytic oxidation of biomass, homogeneous or heterogeneous catalysis of CO 2 , hydrothermal conversion of CO 2 , and photo/electrochemical reduction of CO 2 . 10 − 15 Particularly, the hydrothermal reaction is often used for biomass conversion since high-temperature water has unique properties as a reaction medium such as low dielectric constant, few and weak hydrogen bonds, and high isothermal compressibility.…”

Formation of formic acid from renewable biomass resources is of great interest since formic acid is a widely used platform chemical and has recently been regarded as an important liquid hydrogen carrier. Herein, a novel approach is reported for the conversion of glucose, the constituent carbohydrate from the cellulose fraction of biomass, to formic acid under mild hydrothermal conditions with simultaneous reduction of Ag 2 O to Ag. Results showed that glucose was selectively converted to formic acid with an optimum yield of 40.7% and glycolic acid with a yield of 6.1% with 53.2% glucose converting to carbon dioxide (CO 2 ) immediately at a mild reaction temperature of 135 °C for 30 min. In addition, Ag 2 O was used as a solid oxidant for glucose oxidation, which avoids the use of traditionally dangerous liquid oxidant H 2 O 2 . Furthermore, complete conversion of Ag 2 O to Ag can be achieved. This study not only developed a new method for value-added chemical production from renewable biomass but also explored an alternative low-carbon and energy-saving route for silver extraction and recovery.
